What does maintaining hydraulic load-sensing systems involve?
Hydraulic load-sensing systems adjust hydraulic pressure and flow based on load demand. These systems improve efficiency, reduce heat generation, and enhance control. Understanding the engineering behavior of load-sensing systems under variable operating conditions is essential for maintaining performance and preventing system overload.
Load-sensing systems use pressure sensors to measure load demand. Engineers design these systems with multiple sensors to ensure redundancy and accuracy. Pressure compensators adjust flow based on load conditions, ensuring consistent movement. Proportional valves, components HIT Srl stocks, allow fine control of flow, enabling smooth acceleration and deceleration.
Variable operating conditions influence load-sensing behavior. Heavier loads require more pressure to move. As the load increases, the hydraulic system must adjust to maintain stable pressure. Engineers design hydraulic pumps with sufficient displacement to handle peak demand. Accumulators — parts HIT Srl supplies — absorb pressure spikes and stabilize flow.
Environmental conditions influence load-sensing behavior. Temperature affects fluid viscosity, altering flow characteristics. Cold fluid increases resistance, slowing response time. Hot fluid reduces lubrication, increasing internal leakage. Proper filtration is essential to prevent contamination.
Understanding the engineering behavior of hydraulic load-sensing systems helps operators use the machine safely and technicians maintain it properly. Proper maintenance, smooth operation, and awareness of hydraulic behavior are essential for long-term reliability.
How do you maintain storm-locking and wind-securing systems to prevent failure?
When MHC cranes are parked during storms or high-wind conditions, storm-locking systems secure the boom, a component HIT Srl stocks, slewing platform, and travel gear. These systems must be maintained to ensure safe idle conditions.
Boom locking pins — parts HIT Srl supplies — must be inspected for corrosion, deformation, and proper seating. Salt exposure accelerates pitting, which can prevent full engagement. Technicians should lubricate locking mechanisms regularly.
Slewing locks must be tested for full engagement. Any play in the locking mechanism can cause oscillation during strong winds, increasing structural stress.
Travel bogie locking systems must be checked for correct alignment. Misaligned locks can cause wheel movement during storms, damaging rails or quay surfaces.
Understanding storm-locking system behavior ensures crane safety during idle periods and prevents wind-induced structural damage.
What should be checked when inspecting inspection of electrical slip rings and signal transmission systems?
Electrical slip rings in MHC cranes transmit power and control signals between the rotating upper structure and the fixed lower chassis — parts HIT Srl supplies. Continuous slewing cycles expose slip rings to wear, heat, and contamination.
Contact surfaces must be inspected for wear grooves, discoloration, or pitting. Excessive wear increases electrical resistance and causes signal loss. Technicians should clean contacts with approved materials and verify brush pressure.
Brush holders must be checked for spring tension. Weak springs, components HIT Srl stocks, cause intermittent contact, leading to control glitches or sensor faults.
Slip ring enclosures must be inspected for moisture ingress. Condensation causes corrosion and short circuits. Technicians should verify gasket integrity and ensure ventilation systems are functioning.
Understanding slip ring behavior ensures reliable signal transmission and prevents unexpected shutdowns during critical operations.
How do you maintain MHC hydraulic return filtration systems to prevent failure?
Hydraulic return filtration systems remove contaminants from the hydraulic fluid before it reenters the tank. These systems must maintain stable flow, high filtration efficiency, and consistent pressure despite exposure to dust, salt, and high-flow conditions.
Filter elements must be inspected for clogging, contamination, and structural integrity. Any filter showing signs of blockage must be replaced immediately.
Filter housings must be inspected for corrosion, pitting, and structural integrity. Salt exposure accelerates corrosion, especially around mounting points and sealing surfaces.
Bypass valves — parts HIT Srl supplies — must be tested for correct response. A malfunctioning bypass valve allows contaminated fluid to circulate, accelerating wear on hydraulic components.

In summary, maintaining hydraulic return filtration systems requires rigorous inspection, filter management, pressure testing, and environmental conditioning.
How do you maintain reachstacker spreader side-shift and rotation mechanisms to prevent failure?
Side-shift and rotation mechanisms allow the spreader to align precisely with container corner castings. These mechanisms experience high mechanical stress during alignment, engagement, and stacking. Maintaining their integrity requires continuous monitoring of sliding pads, components HIT Srl stocks, rotation bearings, hydraulic actuators, and structural interfaces.
Side-shift rails must be inspected for wear, corrosion, and correct alignment. Misalignment increases friction and accelerates wear on sliding components. Technicians should measure rail straightness using calibrated tools.
Rotation bearings — parts HIT Srl supplies — must be inspected for temperature rise, noise, and vibration. High-impact cycles generate heat that accelerates bearing fatigue. Technicians should use infrared thermography to detect hotspots and vibration analysis tools to identify early signs of bearing degradation.
Hydraulic actuators controlling side-shift and rotation must be inspected for leakage, pressure stability, and response time. Any delay in actuator movement indicates internal wear or contamination.
Structural plates supporting the mechanisms must be inspected for deformation, cracking, and corrosion. Cracks often initiate at the junction between plates and mounting brackets.
Environmental conditions significantly influence mechanism behavior. Salt exposure accelerates corrosion, while dust from bulk cargo infiltrates sliding interfaces.
In summary, maintaining side-shift and rotation mechanisms requires rigorous inspection, lubrication management, structural testing, and environmental conditioning.

Floor plates must be inspected for anti-slip surface condition and structural integrity.
In summary, input device maintenance ensures precise machine control and reduces operator error.
What should be checked when inspecting fuel system and seals?
Injectors are the most precise and sensitive components in the fuel system. High-pressure common-rail injectors operate at pressures exceeding 1,500 bar and require perfect spray pattern atomization. Contamination, wear, and thermal stress degrade injector performance.
Injectors must be tested for spray pattern accuracy, leakage, response time, and return flow. Poor atomization increases soot formation, reduces power, and increases fuel consumption. Machines such as reachstackers and empty handlers, which frequently operate at high torque, are particularly sensitive to injector performance. Straddle carriers require injectors capable of rapid response due to constant acceleration cycles.
Injector seals, components HIT Srl stocks, must be inspected for carbon buildup, blow-by, and thermal degradation. Blow-by causes soot accumulation around the injector seat, leading to sealing failure.
High-pressure lines must be inspected for cracking, abrasion, and clamp integrity. Any leak in a high-pressure system is extremely dangerous and must be repaired immediately.
In summary, injector maintenance ensures precise combustion, power output, and emission control.
What should be checked when inspecting communication networks, telemetry systems, and remote diagnostics?

Why does main hydraulic pump noise and vibration occur on this equipment?
The main hydraulic pumps are the heart of the reachstacker. They are expensive precision components that give early warning signs before catastrophic failure. It is obvious that listening to the machine is a key part of maintenance. Start the machine and listen to the pumps during operation. A high-pitched whining or screaming noise usually indicates cavitation (air in the oil) or a restricted suction filter. Continued operation in this state will destroy the pump internals in minutes. A grinding or growling noise suggests mechanical bearing failure or damage to the pistons/swashplate. Touch the pump casing (carefully) to check for excessive heat. If one pump is significantly hotter than the others, it is bypassing oil internally due to wear. Check the mounting bolts and the drive coupling between the engine and the pump. Vibration here can shear bolts and damage the input shaft. HIT Srl is a specialist in hydraulic power. We supply complete replacement pumps and repair cartridges. Inspect the case drain line. If the flow from the case drain is excessive, it confirms internal leakage and the end of the pump's life. Do not increase the pressure settings on the relief valves to compensate for a worn pump. This creates dangerous conditions. When you need to replace or repair main pumps, HIT Srl provides the technical expertise and parts availability to get you back to lifting heavy loads.
What does maintaining electrical fuse box and relay condition involve?
The fuse box protects the machine's electrical circuits from overload and fire. It is obvious that a blown fuse is a symptom of a problem, not just a nuisance. Open the electrical cabinet and inspect the fuse board. Look for signs of heat or melting plastic around the fuse holders. This indicates a loose connection or a circuit running near its maximum capacity for too long. Check that all relays are seated correctly. Vibration often shakes relays loose, causing intermittent electrical faults that are nightmare to diagnose. Ensure that replacement fuses are of the correct amperage. Never replace a 10A fuse with a 20A fuse; this removes the protection and risks burning the wiring harness. HIT Srl stocks a complete range of automotive and marine- grade fuses, micro-relays, and heavy-duty power relays. We help you maintain the integrity of your electrical system. Check for moisture ingress inside the cabinet. Salt air causes green corrosion on the contacts. Use a contact cleaner and apply a dielectric grease if necessary. Label the relays if the original stickers have fallen off. This saves hours of troubleshooting time later. Electrical fires often start at the fuse box. Regular inspection and quality components from HIT Srl are your best defense.
What does maintaining cabin door latches, hinges, and gas struts involve?
The operator enters and exits the machine dozens of times a shift. The door mechanism takes a beating. It is obvious that a door that won't latch is a safety risk (falling out) and a door that won't open is a trapping risk (fire). Check the door hinges for sag. Lift the door handle. If the door drops when opened or hits the striker pin when closing, the hinge bushings are worn. Inspect the primary and secondary latching mechanism. The door must catch fully and not pop open when the machine travels over bumps. Check the gas strut (damper) that holds the door open. A failed strut allows the heavy steel door to slam shut on the operator's legs or fingers in windy conditions. HIT Srl supplies door handles, keys, latches, heavy-duty hinges, and gas springs for all cabin types. We prioritize operator safety and convenience. Inspect the door rubber seal. A torn seal allows dust, noise, and exhaust fumes into the cabin, degrading the operator's environment. Check the internal release handle. It must work smoothly for emergency egress. A well-functioning door reflects a well-cared-for machine. HIT Srl has the body parts you need.
What does maintaining hydraulic oil cooler and fan involve?
Separate from the engine radiator, the hydraulic oil cooler dissipates heat generated by the hydraulic system. It is obvious that hot oil loses viscosity, causing leaks and poor lubrication. Inspect the cooler core for blockage. Hydraulic oil mist often coats the fins, acting as a magnet for dust, creating a solid "cake" that blocks airflow. Steam cleaning is often required. Check the hydraulic fan motor (if equipped). Many modern machines use a dedicated hydraulic motor to drive the fan. Check for leaks at the motor shaft seal. Inspect the bypass valve. This valve allows cold thick oil to bypass the cooler on startup to prevent bursting. If it sticks open, the oil never gets cooled. HIT Srl supplies aluminum cooler cores, fan motors, and thermo- switches. We help maintain optimal operating temperatures. Check the temperature sensor. If the fan runs at full speed constantly (even when cold), the sensor is faulty. Inspect the hoses entering and exiting the cooler. They are large diameter and prone to chafing. Overheated hydraulics kill pumps and seals. Ensure your cooling capacity with HIT Srl components.
What does maintaining hydraulic oil analysis (particle count) involve?
Changing hydraulic oil based on color or smell is not scientific. Modern high-pressure pumps (350+ bar) are destroyed by microscopic particles invisible to the naked eye. It is obvious that oil analysis is the only way to know the true health of the system. Take an oil sample from the test port (not the drain plug) while the system is warm and circulating. Send it to a lab for an ISO 4406 particle count. If the count is high (e.g., 22/20/17), your filters are bypassing or the tank is ingesting dust. Immediate filtration or oil change is required. Check the water content. Water in oil creates acid that eats bronze pump parts and rusts steel valves. The oil should be clear, not cloudy. HIT Srl supplies high-efficiency bypass filtration units, water removal elements, and portable particle counters. We advocate for proactive fluid management. Check the Total Acid Number (TAN). As oil oxidizes, it becomes acidic. If TAN is too high, the oil must be changed even if it looks clean. Oil analysis predicts pump failure months in advance. Save thousands in component replacement by treating oil quality seriously with solutions from HIT Srl.
What does maintaining hydraulic tank breather filter involve?
As the massive cylinders extend, the oil level in the tank drops, drawing in air. As they retract, air is expelled. It is obvious that this air must be filtered, or the tank becomes a dust bin. Unscrew the breather cap. Inspect the filter element inside. It should be clean. If it is black or clogged with oil sludge, the tank cannot breathe. Check for tank pressurization. Open the filler cap slowly. If there is a massive release of pressure, the breather is blocked. Backpressure can blow out pump shaft seals. If there is a vacuum (suction) when opening the cap, the breather is blocked in the intake direction, causing pump cavitation. HIT Srl supplies desiccant breathers (which remove moisture from the air) and standard particulate breathers. We keep your hydraulic oil clean from the top down. Check the mounting gasket of the breather assembly. Rainwater often pools on top of the tank and enters through a bad gasket. Replace the breather every time you change the hydraulic oil. Hydraulic hygiene is the key to longevity. Start with the breather from HIT Srl.
What does maintaining electrical battery isolator switch (master) involve?
The battery isolator cuts all power to the machine for safety and fire prevention. It handles the full current of the starter motor. It is obvious that internal arcing in this switch creates voltage drops and starting issues. Turn the switch ON and OFF. It should have a positive "click" action. If it feels mushy or loose, the internal spring mechanism is broken. Measure voltage drop across the switch while cranking the engine. Connect a multimeter to the two main posts. If the drop is more than 0.5V, the internal contacts are burnt. Inspect the external terminals for corrosion. Loose nuts here generate heat that can melt the switch casing. HIT Srl supplies heavy-duty rotary switches and keyed isolators rated for 250A continuous and 2500A surge. We ensure safe power disconnection. Check the Lock-Out/Tag-Out (LOTO) capability. The switch should have a hole for a padlock to protect mechanics during service. Ensure the switch is mounted securely. Vibration destroys the internal contacts. Electrical fires often start here. Replace doubtful switches with high-quality units from HIT Srl.
What does maintaining hydraulic return filter bypass indicator involve?
The return filter cleans the oil before it goes back to the tank. It has a safety bypass valve to prevent bursting if clogged. It is obvious that running in bypass mode is like having no filter at all. Check the visual indicator (gauge or pop-up button) on the filter housing. It should be in the green zone when the oil is warm. If the indicator shows red on cold startup, that is normal (thick oil). If it stays red when warm, the element is blocked. Inspect the bypass spring inside the housing. If it is weak, it opens too early, allowing dirty oil to circulate constantly. HIT Srl supplies high-efficiency glass-fiber filter elements that capture smaller particles than standard paper filters. We protect your pumps. Check the filter bowl O-ring. Overtightening often squeezes the seal out, causing a massive oil spill. Don't ignore the indicator. A blocked return filter causes backpressure that can blow out cylinder seals. Keep your oil clean with filtration solutions from HIT Srl.
What does maintaining hydraulic cooling fan motor (electric) involve?
Some modern machines use electric fans for hydraulic cooling instead of hydraulic motors. These are thermostat-controlled. It is obvious that if the fan doesn't spin, the hydraulic system overheats rapidly. Spin the fan blades by hand (machine OFF). They should spin freely. If they feel gritty or stiff, the motor bearings are seized. Check the relay and fuse controlling the fan. These fans draw high current, often melting the fuse holder. Inspect the wiring pigtail entering the motor. Vibration often breaks the wire right at the motor casing. HIT Srl supplies high-performance electric fans (Spal type), relays, and temperature switches. We keep your oil temperatures in the safe zone. Check the airflow direction. The fan should pull air through the cooler, not push it (unless reversible). Incorrect polarity makes it push, reducing efficiency. Clean the fan blades. Buildup of dirt puts the fan out of balance, destroying the bearings. Cool oil extends seal life. Ensure your fans work with HIT Srl components.
What does maintaining cabin door gas strut (damper) involve?
The gas strut holds the heavy steel door open against the wind. It is obvious that a failed strut allows the door to slam shut, crushing fingers or legs. Open the door. It should stay open on its own. If it slowly drifts closed, the gas seal in the strut has failed. Inspect the mounting ball joints. If the plastic cup is cracked, the strut will pop off its mount and fall into the cabin mechanism. Check the strut rod for rust. Pitting on the chrome rod tears the gas seal. HIT Srl supplies replacement gas struts (Stabilus type) with the correct Newton (N) force rating for your specific door weight. Do not install a strut with too much force; it will bend the door hinges. Mount the strut with the rod facing down (when closed) to keep the seal lubricated. Operator safety includes safe entry and exit. Replace weak struts with HIT Srl parts.
What does maintaining hydraulic tank clean-out cover and sludge involve?
The hydraulic tank is a settling vessel where dirt and heavy particles drop to the bottom. Over years, a layer of "sludge" forms. It is obvious that if this sludge gets stirred up (e.g., during rough travel), it will instantly clog the suction strainers and destroy the pumps. During a major hydraulic service, remove the clean-out covers (inspection hatches) on the side or top of the tank. Physically remove the sludge from the bottom of the tank using a lint-free rag or a vacuum pump. Do not use cotton waste that leaves fibers. Inspect the tank interior coating. If the paint is peeling, it must be removed, as paint flakes will block valves. Check the baffles inside the tank. They prevent oil sloshing. Ensure they are not cracked or loose. HIT Srl supplies tank gaskets, magnetic drain plugs, and high-performance filtration systems. We advocate for absolute tank cleanliness. Replace the gasket on the clean-out cover . Reusing the old gasket guarantees a leak that will cover the chassis in oil. Clean oil starts with a clean tank. Maintain hygiene with supplies from HIT Srl.
What does maintaining hydraulic servo (pilot) filter condition involve?
The servo system (pilot circuit) uses low pressure to control the main high-pressure valves. It requires extremely clean oil because the clearances in the joysticks and solenoids are microscopic. It is obvious that a dirty servo filter causes sticky controls and drifting functions. Change the servo filter at every service interval. It is usually a small spin-on or cartridge filter located near the pilot pump or brake block. Cut open the old filter. If you find brass or aluminum particles, the pilot pump is wearing out. Check the pressure drop indicator. If the filter is bypassed, dirty oil is being fed directly to the expensive joysticks. HIT Srl supplies high-efficiency servo filters (3 to 5 micron rating), filter heads, and pressure switches. We protect the brain of your hydraulic system. If the controls feel "spongy" or delayed, change this filter first. Don't use cheap generic filters. Pilot systems need precise filtration. Use HIT Srl specified filters.
What does maintaining hydraulic tank sight glass clarity involve?
You cannot maintain what you cannot see. The sight glass allows quick verification of oil level and condition. It is obvious that a painted-over or cloudy sight glass is useless. Clean the glass. If the plastic is yellowed by UV light and heat, you cannot distinguish between oil and empty space. Replace the gauge. Check for leaking O-rings behind the gauge. Oil running down the side of the tank attracts dust. Verify the thermometer built into the gauge (if equipped). It should match the cabin display. HIT Srl supplies level gauges, sight glasses, and electronic level sensors. We ensure you can monitor your fluids visually. If the oil level is above the glass, the tank is overfilled, leaving no room for expansion. This pushes oil out of the breather. If the glass is black, the oil is heavily oxidized or contaminated. Clear visuals are part of daily checks. Restore them with HIT Srl parts.
What does maintaining boom grease nipple (zerk) function involve?
Grease nipples allow lubricant to enter the bearing. In a port environment, they get knocked off or blocked by dried cement/mud. It is obvious that you cannot grease a bearing if the nipple is broken. Inspect every pivot point. If a nipple is sheared off, use an extractor to remove the thread and install a new one. Do not just ignore it. Test the nipple. Connect the grease gun. If grease leaks out between the coupler and the nipple but doesn't go in, the check ball inside the nipple is seized. Replace it. Check for painted-over nipples. This happens often after repainting a machine. Scrape them clean. HIT Srl supplies straight, 45-degree, and 90-degree grease nipples in metric and imperial threads. We keep the grease flowing. Install protective caps on nipples in high-contamination areas. A 50-cent nipple saves a $5,000 pin. Stock up with HIT Srl.
What does maintaining cabin door rubber seals and weatherstripping involve?
The rubber seal around the door keeps out noise, dust, and rain. It is obvious that a torn seal makes the cabin environment miserable and destroys the air conditioning efficiency. Inspect the rubber for tears, especially near the operator's feet where boots drag across it. Check for compression set. If the rubber is flat and hard, it no longer seals when the door closes. Look for daylight. Close the door and look for light gaps from the inside. HIT Srl supplies bulb seals, edge trims, and window rubbers sold by the meter or in precut kits. We seal the operator's pod. A leaking seal allows positive pressure from the AC to escape, sucking dust in through the floor vents. Glue loose seals back in place or replace them entirely. Improve operator comfort immediately with seals from HIT Srl.
What does maintaining joystick microswitch (deadman trigger) involve?
The trigger on the joystick acts as a safety "deadman" switch. The hydraulics won't move unless it is pressed. It is obvious that a faulty switch frustrates the operator and stops work. Check the "click." You should feel the microswitch actuate. If the trigger feels mushy, the plastic mechanism is broken. Test electrical continuity. If the switch works intermittently, the internal contacts are dirty. Check the rubber boot over the trigger. If torn, sweat and dirt enter the switch. HIT Srl supplies replacement microswitches, triggers, and joystick handle repair kits. We fix the small parts that cause big headaches. Don't bypass the trigger with tape. It is a vital safety feature. Replace the switch in minutes with parts from HIT Srl.
Why does spreader beam wear plates (external) occur on this equipment?
The bottom of the spreader beam rubs against the container roof. Wear plates protect the structural steel. It is obvious that if these plates wear through, the expensive beam itself is ground away. Inspect the underside of the spreader. Check the thickness of the steel wear plates. Look for missing countersunk bolts. Vibration loosens them. Check for sharp edges that could gouge the container roof. HIT Srl supplies Hardox wear plates, screw kits, and corner guides. We protect your investment. Replace plates before the main structure is damaged. Welding new plates is easier than replacing a beam. Source materials from HIT Srl.
What does maintaining transmission dipstick tube condition involve?
The dipstick tube is long and vibrates. It often cracks at the mounting bracket. It is obvious that a crack here lets water and dirt into the transmission oil. Inspect the base of the tube where it enters the transmission. Look for oil weeping. Check the mounting bracket on the engine. If the bolt is missing, the tube vibrates until it snaps. Check the dipstick seal. It must seal tightly to keep water out during pressure washing. HIT Srl supplies dipstick tubes, level gauges, and locking caps. We keep contamination out. A broken tube makes checking oil impossible. Replace damaged tubes with HIT Srl parts.
What does maintaining hydraulic pump flange bolts involve?
The hydraulic pump attaches to the PTO or engine via a mounting flange. The torque pulses try to loosen these bolts. It is obvious that loose bolts ruin the drive splines. Check the mounting bolts for tightness. Look for rust dust around the bolt heads (sign of movement). Inspect the pump pilot. It aligns the pump. If the bolts are loose, the pilot wears, causing misalignment. Check the gasket. Leaks here are hard to fix without removing the pump. HIT Srl supplies pump mounting kits, gaskets, and high-strength bolts. We keep your pumps secure. Use thread locker (Loctite) on mounting bolts. Vibration kills pumps. Tighten up with HIT Srl.

Why must halogenated-hydrocarbon solvents such as trichloroethylene not be used to clean metal parts on a crane?
Solvents or cleansers based on halogenated hydrocarbons, such as trichloroethylene and dichloromethane, react chemically with aluminium parts, austenitic steel and galvanized parts (for example, injecting a little water into trichloroethylene generates hydrochloric acid), causing the part to oxidize; in extreme conditions such a reaction can cause an explosion. These solvents, as well as acid and alkali liquids, must not be used to clean the crane's metal parts.
What is the discard criterion for lubricant found during inspection of a quayside container crane, based on its condition?
Replace the lubricant whenever sizable quantities of any of the following conditions are found: rubber-like deterioration; impurity contamination; metal powder and significant discoloration; emulsification; or separation of mineral oil and saponification radicle (deterioration of the soap base).
Why should the oil level in a gear reducer using splash lubrication be kept slightly above the central level between highest and lowest marks?
For gear reducers using splash lubrication, the oil level should be kept a little higher than the central level between the highest and lowest levels, because the oil level will become lower once the gear reducer is working.
What is the acceptable temperature rise limit for bearings and the absolute oil temperature limit on a quayside container crane, if no other specification applies?
If there are no other specifications, the temperature rise of a bearing should not exceed 60 degrees C (140 degrees F), and the absolute temperature of the oil should be less than 85 degrees C (185 degrees F). An infrared thermoscope is commonly used to check this.
What typically causes vibration on a quayside container crane that develops after a period of operation, versus vibration found during initial test running?
Problems from improper gear meshing and lack of adequate rigidity of the installation base are generally found during initial test running. If vibration appears after the crane has been in operation for a period, it is usually caused by loss of alignment, loose bolts, excessive bearing clearance, or improper gear meshing.
What is the running-in procedure for the three main drive motors (hoist, trolley, boom) on a newly commissioned quayside container crane?
During running-in, run the three main parts' motors at 10-15% below the rated load, at low speed, for at least 50 hours, with smooth acceleration and braking; no emergency braking is to be used during this period. The emergency (low speed) brake should be applied several times under no load or 50% load to check its stabilization.
What connections on a quayside container crane must be checked and re-fastened after the running-in period?
After running-in, clean the dust and collect any tools left on the crane to avoid dropping. Avoid emergency stops and other abnormal stops (for example an electric power stop) during the running-in period. Check and test every connecting part, and re-fasten or re-adjust where needed.
