Application:

● OFFSHORE CRANES

● TOWER CRANES

● FLOATING CRANES

● MINING SHAFTS

● WIND TURBINE INSTALLATION

Advantage:

● Hoist winch:

1.Function: vertical lifting/lowering of loads

2.Drive: Hydraulic motor A+ Dedicated gearbox A

● Lufting winch:

1.Function: Adjusting boom/jib angle（radius control).

2.Drive:Hydraulic Motor B+Dedicated gearbox B.

Hoist & luffing operate simultaneously without interference

● One motor/gearbox fails--Other maintains critical function

● Dual gearboxes share load torque,reducing individual component stress

● Synchoronized motors enable micro-adjustments(±1mm precision)

● Dual systems absorb/dissipate peak forces

● Hoist gearbox:high torque/low speed;Luffing:faster response

● Isolate/repair oe system without full shutdown

● Load-sensing HPU directs flow only to active winch;idle motor consumes zero
