The GFT330W3 hydraulic winch drive is designed for winch systems that require planetary gear reduction and a hydraulic motor input. It combines a high-torque reduction gearbox with a compatible hydraulic motor and braking configuration to support controlled winch operation.
The listed configuration provides a maximum output torque of 275,000 N·m, four reduction ratios and multiple hydraulic motor options. Selection should be based on the required drum torque, rope speed, hydraulic supply, braking requirements and installation dimensions of the complete winch system.
A hydraulic winch drive converts hydraulic power into mechanical rotation to turn the winch drum. The complete system typically includes a hydraulic power source, hydraulic motor, planetary reduction gearbox, braking components and control valves.
Hydraulic power source: A hydraulic pump supplies pressurized oil through the machine's hydraulic circuit.
Hydraulic motor: The motor converts hydraulic energy into rotational mechanical power.
Planetary reduction gearbox: The gearbox reduces input speed and transmits torque to the winch mechanism.
Winch drum and brake: The output drives the winch drum, while the specified braking system provides the required stopping and holding function.
Hydraulic control valves: The control circuit regulates the operating direction and speed and coordinates brake operation according to the system design.
The hydraulic motor, reduction gearbox, brake and control circuit must be selected as a compatible system. Safe operation depends on the ratings and installation of the complete winch assembly, not on the drive unit alone.
The planetary reduction gearbox transfers motor output to the winch mechanism. The required gear ratio should be selected according to the target drum speed, required pulling force and operating load.
The supplied technical data lists A2FE160, A2FE180, A2FE250 and A2FE355 motors, together with A6VE160, A6VE250, A6VM200 and A6VM355 options. The final motor selection depends on displacement, hydraulic pressure, oil flow, input speed and interface compatibility.
The listed ratios are 169, 210, 252 and 302. Each ratio produces a different relationship between motor speed and gearbox output speed, so the ratio should be matched to the required winch performance.
The GFT330W3 specification lists a maximum braking torque of 2,500 N·m and a brake pressure range of 1.8–5 MPa. Confirm the brake configuration and its suitability for the actual load, duty cycle and winch safety requirements.
Gearbox mounting dimensions, input motor interfaces, output connections and brake requirements should be checked against the winch design and the host equipment drawings before installation.

Hydraulic winch drives can be considered for compatible marine and offshore winch systems, including selected mooring and anchor-handling applications. Suitability depends on the required load rating, environmental protection, braking arrangement and applicable project requirements.
For construction machinery and crane-related systems, the drive ratio, drum torque, hydraulic motor and braking components must match the machine's lifting or pulling requirements.
Selected mining and drilling applications use hydraulic winch systems for pulling and positioning operations. The drive unit must be matched to the operating duty, load conditions and hydraulic circuit.
Hydraulic winch systems can be used for suitable timber-pulling and cable-handling equipment. Selection should account for the rope arrangement, line pull, operating conditions and required control functions.
Winch drives may also be evaluated for recovery and special-purpose pulling equipment when the mechanical interfaces, braking requirements and operating limits meet the application specifications.
A suitable winch drive should be selected by reviewing the mechanical, hydraulic and braking requirements of the complete system. Before requesting a quotation, prepare the following information where available:
