Winch types include construction winches and coaxial winches.
Key products include: JM series (electrically controlled, slow-speed, high-tonnage and standard models), JK series (electrically controlled, high-speed), JKL series (manually controlled, high-speed lowering), 2JKL series (manually controlled, dual-speed lowering), dual-mode (electric/manual) winches, JT series (variable-speed), and KDJ series (miniature winches). While designed for ground-based operation, they can be modified for marine use. Powered by an electric motor, the winch drives the drum via an elastic coupling, a three-stage enclosed gear reducer, and a jaw coupling; it utilizes an electromagnetic braking system.
These winches are characterized by high versatility, compact structure, small size, light weight, high lifting capacity, and ease of relocation. They are widely used for material lifting or horizontal hauling in construction, water conservancy projects, forestry, mining, and port operations, and can also serve as auxiliary equipment for modern, electrically controlled automated production lines. The JM series features gear-reducer transmission and is suitable for civil engineering and installation projects undertaken by construction companies, mining operations, and factories.
