The GWL5 free fall hydraulic winch is designed for lifting and controlled or free-fall lowering applications where high pulling capacity, compact planetary transmission and reliable load handling are required. Available configurations cover 5–10 ton load capacity, with customized hydraulic and rope configurations for different machines.
GWL5 free fall hydraulic winches are suitable for heavy-duty machinery requiring lifting, lowering and high-capacity rope handling. Typical applications include:
High-capacity hoisting and lowering operations on crawler crane systems.
Hydraulic lifting and lowering systems for truck-mounted and vehicle crane applications.
Winch systems for pipe-laying machinery requiring reliable load lowering and positioning.
High-speed lowering and lifting applications where free-fall capability is specified.
Hydraulic winch systems for selected crushing and material-handling equipment.
Customized configurations for OEM machinery with specific lowering and pulling requirements.
Depending on the specific configuration, a free-fall winch can use a hydraulic clutch and brake arrangement to allow rapid load lowering. Different designs may provide emergency free fall, controlled free fall, or both.
The winch combines hydraulic drive with planetary reduction to convert motor speed into the torque and rope speed required by the application. This architecture is widely used in compact heavy-duty winch systems. :contentReference[oaicite:2]{index=2}
Free-fall winch architectures can include multi-disc or wet brakes, hydraulic clutches and control valves to manage lifting, holding and lowering functions. The exact control method depends on the selected configuration. :contentReference[oaicite:3]{index=3}
Hydraulic motor, planetary gearbox, brake and clutch components can be integrated into a compact winch package to support installations where available space is limited.
A free-fall or free-lowering function is not identical across all hydraulic winches. Depending on the design, the function can be created by a clutch and brake arrangement or by a hydraulic control system designed specifically for high-speed lowering. Therefore, operators should use only the operating mode specified for the actual winch model. :contentReference[oaicite:4]{index=4}
01. Hoisting
Hydraulic power drives the motor and transmission to rotate the drum and raise the load.
A model-specific clutch, brake or hydraulic control system enables the specified lowering mode.
Controlled free-fall systems may regulate lowering speed and provide stopping capability according to the winch design.
Before operating a free-fall hydraulic winch, confirm that the winch configuration, load and machine installation are suitable for the intended duty.
Confirm whether the winch provides emergency free fall, controlled free fall, or another specified lowering mode.
Verify the load against the applicable capacity and make sure the rope, hook and rigging are in suitable condition before operation.
Keep personnel outside the designated exclusion area and make sure the lowering path is clear.
Operate the clutch, brake and hydraulic controls exactly as specified for the selected winch. Do not assume that a generic free-fall procedure applies to every model.
| Model | 1st Layer Pull | Rope Speed | Brake / Clutch Opening Pressure | Displacement | Working Pressure Difference | Rope Diameter | Rope Capacity | Hydraulic Motor | Planetary Reducer |
|---|---|---|---|---|---|---|---|---|---|
| GWL5-80-120-24-ZP | 50 kN | 0–40 m/min | 2.5–3.0 / 5.0–7.0 | 9,977 ml/r | 14.8 MPa | 24 mm | 120 m | NAM16-1800D240101 | C5D |
| GWL5-100-100-28-ZP | 100 kN | 0–40 m/min | 2.5–3.0 / 5.0–7.0 | 12,468 ml/r | 14.2 MPa | 28 mm | 100 m | NAM16-2400D240101 | C5D |
Final configuration and operating limits should be confirmed against the approved technical drawing and winch specification.
A typical free-fall hydraulic winch can integrate a hydraulic motor, planetary gearbox, brake, clutch, drum and frame. Exact component architecture varies by model and application. :contentReference[oaicite:5]{index=5}

The winch is prepared for international shipment according to the confirmed order and packaging requirements.
The main information includes required line pull, rope speed, rope capacity, lifting or lowering direction, working environment, hydraulic pressure and flow, and the intended machine application.
Yes. Custom configurations can be evaluated according to required line pull, rope capacity, rope speed, mounting arrangement, hydraulic motor and planetary gearbox configuration.
Free-fall systems and controlled free-fall systems use different mechanisms and control strategies. Some systems allow rapid lowering, while controlled designs regulate the lowering speed and may provide stopping control. The exact function depends on the winch configuration. :contentReference[oaicite:6]{index=6}
Typical applications include crawler cranes, vehicle cranes, pipe-laying machines, grab-bucket cranes and selected crushing equipment. :contentReference[oaicite:7]{index=7}
OEM and customized configurations can be evaluated according to the required pull, rope speed, rope capacity, hydraulic system, installation space and machine application.
