Mobile Harbour Crane (MHC) Spare Parts: Specialized Technical Sourcing
The complexity of Mobile Harbour Cranes demands a spare parts partner with genuine, hands-on knowledge. HIT SRL's expertise in MHC components is directly tied to the technical foundation laid at Fantuzzi Reggiane.
As the leader of the MHC technical development department at Fantuzzi Reggiane for many years, Paolo Soncini gained an intimate, practical understanding of every structural, mechanical, and electrical subsystem. This global experience, forged by travelling the world multiple times to commission and support these magnificent machines, enables HIT SRL to recognize and procure complex MHC spare parts with surgical precision, even when dealing with models long forgotten by standard suppliers.
The Anatomy of an MHC: Deep Technical Sourcing
Our supply chain covers every critical system of a Mobile Harbour Crane, ensuring we can support major overhauls and emergency repairs alike.
Axles & Steering Systems
The mobility of an MHC relies on complex multi-axle chassis systems designed to bear immense loads while offering precise maneuverability. We supply genuine components for the entire undercarriage.
- Kessler Axles: Complete axles, differentials, and planetary hubs for the industry-standard Kessler drive and steer axles.
- Steering Cylinders: Heavy-duty hydraulic cylinders for multi-mode steering (crab, circle, parallel).
- Suspension: Hydropneumatic suspension cylinders, accumulators, and leveling valves for chassis stability.
- Braking: Wet disc brake kits, calipers, and pneumatic brake valves.
- Tie Rods & Linkages: Precision steering arms and bushings to maintain alignment.
Stabilizers (Outriggers)
Safety begins with stability. We provide the robust components necessary to ensure your crane remains perfectly leveled and secure during lifting operations.
- Stabilizer Pads: Heavy-duty steel or composite pads for ground load distribution.
- Locking Valves: Safety check valves to prevent cylinder creep or failure under load.
- Hydraulic Cylinders: Vertical jacks and horizontal extension cylinders.
- Position Sensors: Linear transducers and proximity switches for auto-leveling systems.
Winches & Hoisting Gear
The heart of the lifting capability. We source components for main hoist and luffing winches, ensuring smooth and powerful vertical movement.
- Winch Drums: Grooved drums for precise rope spooling.
- Motors & Brakes: Hydraulic or electric motors and fail-safe disc brake calipers (Pintsch Bubenzer, Twiflex).
- Gearboxes: High-torque planetary reduction gears (Brevini, Siebenhaar, Zollern).
- Luffing Units: Components for the boom elevation mechanism.
Ropes, Sheaves & Pulleys
The critical interface between the crane and the load. We supply certified lifting media and wear parts to prevent premature failure.
- Steel Wire Ropes: High-performance, rotation-resistant ropes for main hoist and luffing (Casar, Teufelberger).
- Sheaves (Carrucole): Nylatron or Steel sheaves for boom heads and hook blocks.
- Bearings: Heavy-duty roller bearings for sheaves.
- Hook Blocks: Complete blocks, safety latches, and swivels.
- Rope Guides: Protection systems to prevent rope damage on the drum.
Cable Reels & Power Transfer
For electric-drive MHCs, the power and data link is vital. We supply complete reel systems and internal components.
- Cable Reels: Motorized reels for MV power and fiber optics (Conductix-Wampfler, Cavotec, Stemmann).
- Slip Rings: Collector bodies and carbon brushes for continuous rotation.
- Drive Motors: Torque motors for constant tension control on the reel.
- Cables: Specialized reeling cables resistant to UV, oil, and mechanical stress.
Gearboxes & Slewing Drives
Precision rotation requires high-quality gearing. We supply the reduction units that allow the crane to slew smoothly under load.
- Slewing Gearboxes: Planetary reduction units (Brevini, Dinamic Oil, Bonfiglioli).
- Pinions: Induction-hardened drive pinions.
- Slewing Rings (Ralle): Large diameter bearings for the interface between tower and chassis (Rothe Erde, Rollix).
- Seals & Gaskets: Maintenance kits to prevent oil leaks and contamination.
The Obsolete Electronics Challenge Solved by Expertise
Solving the Obsolete Electronics Crisis
Many older MHC models suffer from crippling downtime due to obsolete onboard electronics. We are experts in machines featuring legacy control systems, including:
- Black and white master control screens.
- Pulpits with 30-button consoles and "umbilical cord" control systems.
- Outdated input/output (I/O) slave boards present in panel enclosures.
- Carriage-side PLCs that are now virtually impossible to source through official channels.
Leveraging the deep knowledge gained during years in Reggiane's technical division, HIT SRL is uniquely positioned. We are aware of the existence of a few rare, reconditioned, and verified units of crucial electronic components: Master Controllers, I/O Slave Boards (Slave), Carriage PLCs (PLC carro), Anemometer Boards (schede anemometro), and Cabin Pulpits (pulpiti cabina). These are available to keep your classic MHCs operational.
Trust the technical lineage. Partner with HIT SRL to procure the precise, quality-assured MHC components your fleet demands.
