The GWL4 Hydraulic Crane Winch is a hydraulic winch designed for lifting, pulling and load-handling applications on cranes and other heavy-duty equipment. The GWL4 series is available in configurations covering approximately 5–6 ton load capacity, with different rope, motor and planetary reducer combinations.
Depending on the configuration, the GWL4 provides a first-layer pulling force of 50–60 kN, rope speeds up to 40 m/min, and wire rope capacities of 90–100 m for the listed models.
Crawler cranes
Truck-mounted cranes
Pipe lifting and handling equipment
Drilling and grab equipment
Construction machinery
Heavy-duty lifting and pulling systems
The GWL4 uses a hydraulic motor and planetary reduction system to transmit power to the winch drum for controlled lifting and pulling operations.
The GWL4 product range covers approximately 5–6 tons, with detailed configurations providing 50 kN or 60 kN first-layer pulling force.
The listed GWL4 configurations provide a rope speed range of 0–40 m/min. Actual operating speed depends on the hydraulic system, motor configuration and winch working conditions.
The GWL4 configurations include specified brake and clutch opening pressure ranges to support controlled winch operation. Selection should be matched to the hydraulic circuit and machine requirements.
The winch integrates a planetary reducer to provide torque multiplication and the required output speed for lifting and pulling applications.

A clutch is used in some hydraulic winch configurations to control the connection between the drum and the drive system. Depending on the winch design, the clutch can assist with drum engagement and disengagement during setup, rope handling or specific operating conditions.
The clutch and brake configuration should be selected according to the winch design, load requirements and hydraulic control system. Actual operating procedures should follow the manufacturer's technical documentation.
Before selecting a GWL4 configuration, confirm the required pulling force, rope diameter, rope capacity, operating speed, hydraulic pressure, motor displacement and installation space.
Required pull: Select the configuration according to the required first-layer pulling force.
Rope specification: Confirm rope diameter and required rope storage capacity.
Hydraulic system: Match motor displacement and working pressure with the machine hydraulic circuit.
Installation: Confirm drum, mounting and connection dimensions before ordering.
Payment: 30% deposit and 70% before shipment for regular orders. Customized orders may use different payment terms according to the project.
Delivery: 35–40 days after receipt of payment.
