K series hardened gear reducer it features smooth operation and low noise, providing enhanced durability and reliability.
Mechanical height limiter the upper and lower limits can be flexibly set according to requirements, effectively controlling the working range of the winch, thereby reducing the risk of accidents.
This servo-driven double drum electric winch is designed for applications where two drums must move in precise coordination. With closed-loop servo control, encoder feedback and PLC/HMI integration, it delivers accurate, repeatable lifting and pulling for industrial lines, test benches, long-travel positioning and special equipment. Drums, steel wire rope, level-wind, control cabinet and HMI can all be customized to match your project.
Key Features & Benefits
True synchronized motion: Two drums run in precise sync with encoder feedback. Configurable for equal speed, equal length or ratio-based electronic gearing.
Closed-loop accuracy: Servo drive + encoder maintain speed and position even under changing loads, ideal for labs, endurance lines and delicate fixtures.
Constant speed / constant tension modes: Switchable control logic lets you hold a target line speed or maintain a defined tension window when your process requires.
Safety-first design: Electromagnetic or fail-safe brakes, torque limits, upper/lower travel limits, over-travel protection and integration into your emergency-stop chain.
Industrial PLC/HMI control: Touch-screen HMI for setpoints, recipes and diagnostics, with PLC/SCADA connectivity via digital/analog I/O and common fieldbus protocols.
OEM/ODM flexibility: Drum groove pattern, level-wind, rope diameter, gear ratio, protection rating, finish and language can all be tailored to your site and standards.

What is the weight of the product
2000 KG
How precise is the synchronization between the drums?
With dual encoders and servo control, the controller keeps the commanded relationship between drums very tight. For equal-length mode we calibrate encoder counts to the rope circumference; for ratio mode we apply electronic gearing between drums to maintain the set ratio.
Can the winch maintain a target tension instead of a fixed speed?
Yes. When equipped with load cells, the tension loop can be closed in the controller. The system then modulates torque and speed to keep the rope tension within the defined band, which is useful for test benches and delicate pulling processes.
What happens during an emergency stop or power failure?
In an emergency stop, the drives execute a controlled stop and the brakes engage according to the safety sequence. In case of power failure, the brakes close to hold the load, and optional backup power can keep the controller alive for an orderly stop and data recording.
Can this winch be integrated with our existing PLC/SCADA system?
Yes. We provide digital and analog I/O and can support mainstream industrial protocols such as Modbus, Profinet or Ethernet-based networks according to your project. Setpoints, recipes and status tags can be mapped to your line PLC, DCS or MES for unified control and monitoring.
Do you offer stainless-steel or special-environment versions?
For harsh, marine or wash-down environments we can supply stainless-steel cabinets and hardware, sealed bearings, enhanced coatings and heaters. Protection grades and materials are selected according to your site conditions and specifications.
