Kalmar ContChamp DRD-S: how is the hydraulic system laid out?
In two possible layouts, one with a common tank for all circuits and one with separate tanks for working hydraulics and brakes, according to the DRD-S technical handbook (2004 edition), as recorded by the HIT SRL technical desk. Both use two double variable pumps for lift, extension, servo, steering and attachment and a fixed vane pump for the brakes, the handbook states, as HIT SRL's technical desk reads it. The separate-tank version adds a vane pump and a radiator for the oil of the main tank, in the same handbook.

It has its own control unit, linked to the main control unit by a CAN bus, and a main valve fed by a variable pump, according to the DRD-S technical handbook (2004 edition), the HIT SRL technical desk notes. According to the handbook, length adjustment is by hydraulic motor and chain and the rotation brake is fully hydraulic, except on machines with a combi attachment or a pile-slope top lift, as set out in the HIT SRL technical cards. Its top-lift section gives the side shift as 800 mm with two cylinders and the length adjustment with two chains.

Kalmar ContChamp DRD-S: what are its brake accumulators like, and how are they checked?
Membrane-type accumulators pre-charged with nitrogen to 100 bar, with the pre-charge checked at least once a year, according to the DRD-S technical handbook (2004 edition), as recorded by the HIT SRL technical desk. In the handbook the check takes one accumulator at a time, with the other three disconnected and their connections plugged, and a 0-250 bar gauge on the charging valve, as HIT SRL's technical desk reads it. The DC handbooks give piston-type accumulators at 95 bar instead.

Kalmar ContChamp DRD-S: when are the parking brake linings changed after emergency braking?
It depends on the section: the DRD-S technical handbook (2004 edition) says to check and replace if necessary in some sections, after two emergency operations in another and after any emergency operation in a third, as recorded at HIT SRL. The check-and-replace rule stands in the safety regulations and in a transmission section, the two-operation rule in the parking brake description and the any-operation rule in the brake system service pages, as logged by the HIT SRL technical desk. The DC handbooks change the pads after two emergency operations, and the rule for a given truck is stated in the manual of the specific machine.

By magnetic powder or penetrant testing, with any crack, split or other visible damage meaning immediate replacement, according to the DRD-S technical handbook (2004 edition), as HIT SRL's technical desk reads it. The handbook places the first check after 5000 hours or 2 years, whichever comes first, then every year, and all lifting pins are replaced after 20,000 hours even if they look undamaged, as recorded by the HIT SRL technical desk. The lubrication chart of the top lift says to dismantle and check the twist-locks every 5000 hours, and the pin intervals for a given truck are those in the manual of the specific machine.

Stay in the cab gripping the steering wheel and never try to jump out, according to the DRD-S technical handbook (2004 edition), the HIT SRL technical desk notes. The handbook also asks for the seat belt to be worn where fitted, for a speed suited to load, visibility and ground, and for care near power lines and quay edges, as set out in the HIT SRL technical cards. Getting on and off is by the steps and handles only, and the rules for a given truck are those in the manual of the specific machine.

By pulling out the knob on the solenoid of the lift cylinder blocking valves and turning it a quarter turn, which lets the boom sink slowly, according to the DRD-S technical handbook (2004 edition), as recorded at HIT SRL. The handbook gives this lowering for an electrical fault that keeps the blocking valves closed, and only on an unloaded machine, as logged by the HIT SRL technical desk. An emergency lowering on a real truck follows the manual of each machine.

The operator, who must make sure the truck carries approved fire extinguishing equipment under the regulations in force, according to the DRD-S technical handbook (2004 edition), as HIT SRL's technical desk reads it. The handbook forbids operation if safety equipment such as mirrors, headlights or the optional reversing alarm does not work.

The accumulators are emptied into the tank with the evacuation valve, and the valve for emergency servo pressure is opened as well, according to the DRD-S technical handbook (2004 edition), as set out in the HIT SRL technical cards. The handbook also asks for the engine to be stopped at once if the charging pressure exceeds the values on the plate of the hydraulic system, the HIT SRL technical desk notes. The depressurising sequence for any truck in service is the one in its own maintenance manual.

With the wheel on the opposite side blocked and the blocks cribbed up, so that the jack cannot slip, according to the DRD-S technical handbook (2004 edition), as logged by the HIT SRL technical desk. The RS technical handbook (1996 edition) has the steered wheel end jacked up and blocked up safely before work on bearings and knuckle pins, as recorded at HIT SRL. Jacking points and blocks on a working truck are set by the manual of the individual machine.

Kalmar ContChamp DRD-S: how does the ECS signal a fault?
A red lamp blinks on the terminal and an error message appears, according to the DRD-S technical handbook (2004 edition), as recorded by the HIT SRL technical desk. Faults 01 to 08 belong to level 2 and need a repair before any reset, whereas the R key resets the other errors; an unrepaired fault makes the lamp blink again within 3 to 10 minutes, the handbook states, as HIT SRL's technical desk reads it. Most of errors 01 to 08 reduce the engine speed, and the handbook asks the operator to stop as soon as possible and call for service.

Kalmar ContChamp DRD-S: what do some ECS messages ask the operator to do?
To check and top up the level on low engine oil pressure, high coolant or gearbox temperature or low coolant level, according to the DRD-S technical handbook (2004 edition), the HIT SRL technical desk notes. On very low fuel the handbook asks for the tank to be filled to keep air out of the system, and on low brake pressure or an exceeded service interval it calls for service, as set out in the HIT SRL technical cards. When a twist-lock sensor signal lasts more than 60 s after unlocking, the contact pins are checked for free movement, as the handbook gives.

It is also heavier, 65,700 kg against 60,400 kg in service, and at load centre L2 the sheets give it 21,000 kg against 24,000 kg, as recorded by the HIT SRL technical desk. Its load chart drops to 8 t in the third row where the DC4160RS4 chart shows 11 t.

The 1995 manual fills axle, rotator reduction gear and top-lift motor gear with one API GL-5 SAE 80W-140 oil, as recorded at HIT SRL. In the 1996 handbook the rotator brake takes ordinary hydraulic fluid without additive and only its planetary gear GL-5 oil, and the 1995 manual gives 700 l for the hydraulic system.

On the steering axle, the 1990 technical handbook tightens the bearing nuts against a stop with no torque values, while the RS technical handbook (1996 edition) sets 500 Nm on the wheel bearing nuts and 1750 and 1500 Nm on the knuckle-pin nuts, as recorded by the HIT SRL technical desk. For the hydraulics, the 1990 handbook gives three gear-type pumps and the 1996 handbook four vane-type pumps, as HIT SRL's technical desk reads it. Both drive the pumps from take-offs on the torque converter, according to the two handbooks.
