Slow Speed Electric Winch Features
- Precise Speed Control: The electric control slow winch achieves accurate adjustment of drum speed through an electronic control system. With a typically slow lifting speed (generally 8–15 m/min), it provides higher precision and stability, making it suitable for applications requiring extremely smooth lifting—such as the installation and commissioning of large equipment and the handling of precision instruments.
- Convenient and Safe Operation: Using an electric control system, operators can control the winch’s start, stop, acceleration, and deceleration through control buttons or a remote device, eliminating the need for close-range operation and improving safety and convenience. It is also equipped with multiple safety features, such as brakes and limit switches, ensuring safe operation throughout the working process.
- Compact and Reliable Structure: Usually driven by a gear reducer, the winch features a compact structure with small size and light weight, making it easy to install and move. Some models adopt an integrated design that incorporates the motor, reducer, brake, and drum into one frame, reducing the required footprint and simplifying installation.

The function of the winch’s hand-controlled lowering device is to manually achieve smooth lowering of the wire rope or load, effectively preventing rapid slippage or loss of control and ensuring a smoother, safer, and more controlled lowering process.
Equipped with two drums, it can wind wire ropes simultaneously or independently, providing double pulling capacity or enabling different operating modes. It is suitable for applications requiring high traction force or the simultaneous handling of multiple loads.
Some models can also adopt an integrated design that combines the motor, reducer, brake, and drum into a single frame, reducing the footprint and simplifying installation.
Customized Applications of Slow Speed Electric Winch
Bridge Erection
The hoisting winch used in bridge erection is primarily responsible for lifting, lowering, and precisely positioning bridge segments or girders, serving as a key power unit of the bridge erection machine. By winding and unwinding the wire rope, the winch enables smooth and safe lifting operations while providing reliable braking and protection functions to ensure stability during heavy-duty hoisting.
Girder Lifting in Beam Fabrication Yard
The main function of a winch is to perform vertical lifting, smooth lowering, and precise positioning of girders, providing core power support for beam fabrication, storage, and transportation processes. By winding and unwinding the wire rope to drive the lifting gear, the winch enables the safe and efficient handling of heavy girders. It is also equipped with brakes, limit switches, and overload protection devices to ensure stable and reliable operation.
Dam Gate Opening and Closing in Hydraulic Engineering
Winches for hydraulic engineering are primarily used in the gate hoist rooms at the top of hydropower stations, depending on the arrangement and layout of the units. By synchronously connecting multiple electric slow-speed winches in series, they enable the simultaneous opening and closing of multiple gates.
