MANUFACTURER DOCUMENTATION
Overview
Weili’s winch reducer drives a cable drum through a multistage planetary gear train. The manufacturer describes a compact construction, an integrated parking brake and compatibility with several variable- and fixed-displacement hydraulic motor series. Its ratio envelope is 26–420 and the published maximum-output-torque envelope is 7.5–325 kNm. Those maximum values must not be presented as continuous rated torque. A winch selection also needs the drum diameter, line pull, reeving arrangement, speed cycle and braking duty. Confirm the complete motor/reducer/brake assembly and the manufacturer’s load calculation before using it in lifting equipment.

Before you specify this gearbox
A planetary gearbox shares load across several planet gears. Confirm nominal and peak torque separately, together with ratio, input speed, backlash and mounting dimensions.
- Confirm continuous, peak and emergency-stop load limits separately.
- Match the motor flange, shaft, mounting orientation and lubrication requirements.
- Request the current drawing revision and selection calculation from the manufacturer.
