KEY TECHNICAL FEATURES

Internal Motor & Gearbox Structure

Features an axial piston motor and reduction gear built directly inside the drum, significantly reducing overall dimensions and installation space.

Counterbalance Safety Valve

Integrated counterbalance valve prevents load dropping and ensures smooth, controlled lowering even under dynamic load variations.

Internal Multi-Disc Parking Brake

Spring-applied, hydraulically released multi-disc wet brake provides dynamic holding security and emergency braking reliability.

High-Strength Structural Frame

Heavy-duty welded steel frame and reinforced drum built to withstand severe torsional and bending stress during maximum pull.

High-Efficiency Piston Motor

Delivers smooth starting torque, low noise operation, and high volumetric efficiency across full working pressure range().

Optional Rigidity Steel Wire Rope

Available with high-tensile, rotation-resistant steel wire rope tailored for specialized lifting requirements.

Frequently Asked Questions

What is a compact hydraulic winch?

A compact hydraulic winch is a winching device powered by a hydraulic motor. The WEITAI CHW Series integrates an axial piston motor and reduction gear directly inside the drum to provide a compact configuration for towing and lifting applications.

What models are available in the WEITAI CHW Series?

The CHW Series includes seven models: CHW-02, CHW-05, CHW-08, CHW-10, CHW-15, CHW-20 and CHW-30. Each model has different hydraulic and dimensional specifications.

What is the maximum working pressure of the CHW Series?

According to the product brochure, the maximum working pressure is 27 MPa for CHW-02, CHW-05 and CHW-08, and 30 MPa for CHW-10, CHW-15, CHW-20 and CHW-30. Confirm the operating conditions and hydraulic system compatibility before selection.

Does the CHW Series include a braking system?

Yes. The product brochure specifies a multi-disc parking brake and a counterbalance valve as standard features across all models. The complete system must be designed and configured for the intended application.

Can the compact hydraulic winch be installed inside equipment?

Yes. The brochure states that the winches can be installed directly within equipment or at another desired location. The final mounting arrangement must be verified against the applicable dimensions, interface and installation requirements.

Is steel wire rope included?

Steel wire rope is listed as an optional feature. Confirm rope specifications, supply scope and termination requirements when requesting a quotation.

How do I choose the right hydraulic winch model?

Start with the required line pull, rope speed, hydraulic working pressure, available flow, duty cycle, rope diameter, rope length and installation space. Provide these details to WEITAI for technical review and model selection.

How can I request a quotation for the CHW Series?

Submit your preferred model, equipment application, hydraulic parameters, estimated quantity and target delivery location through the inquiry form. If you are unsure which model to select, submit your equipment details for a technical consultation.
