Electric Winch

Heavy Duty Electric Winch Machine is the core hoisting mechanism of the crane, mainly used for wire rope winding and releasing, so as to realize the vertical lifting, horizontal, or inclined dragging of heavy loads. Usually used in conjunction with gantry cranes, bridge cranes, tower cranes, etc. Industrial Winch Machine is characterized by high versatility, compact structure, small volume, light weight, heavy lifting, and convenient transfer. Widely used in construction, water conservancy projects, forestry, mining, dock, and other materials lifting or flat towing, is the modernization of electronically controlled automatic work line supporting equipment.

It is mainly composed of an electric motor/hydraulic motor, a reducer, a wire rope reel, a brake, a control system, etc. The following are the characteristics of each part:

Electric motor/hydraulic motor: provides power (electric or hydraulic drive).

Reducer: reduces the speed, increases the torque, and smooths lifting.

Reel: Wrap the wire rope to control the lifting and lowering.

Brake: Emergency brake to prevent heavy objects from falling.

Wire rope: connecting the hook or grab, carrying the load.

Control system: Adjust the speed and direction to realize precise operation.

• Low-speed & high-torque transmission: Multi-stage hard tooth gear reducer, stable low-speed running, micro-adjust positioning for heavy installation.
• Dual safety braking system: Main electromagnetic brake + auxiliary safety brake for heavy tonnage models, double anti-slip protection.
• Thickened integral steel drum, CNC machined rope groove, neat wire rope arrangement, extend wire rope service life.
• Sturdy welded base frame, high structural rigidity, stable operation without vibration under full load.
• Multiple control modes: On-site button cabinet, wired pendant control, wireless remote control optional.
• Wide power compatibility: 380V/400V/415V/690V, 50/60Hz, meet domestic and export market standards.
• Complete protective design: IP54 motor, F-class insulation, dustproof sealed gearbox, marine anti-corrosion coating for coastal projects.
• Large rope capacity design: Drum can store 20–3600m steel wire rope, fit long-distance traction and lifting demands.

• Ultra-high safety factor, slow running speed effectively reduce impact and collision risk during heavy component hoisting.
• Strong overload resistance, stable continuous M4/M5 working class, support long-time heavy-duty operation.
• Simple mechanical structure, easy disassembly and daily maintenance, spare parts low procurement cost.
• Flexible installation: Fixed on ground, platform, ship deck or matched with crane trolley as lifting mechanism.
• Low noise gear transmission, little vibration, suitable for precision equipment assembly and bridge prefabrication.
• High cost performance compared with imported open winch, ideal choice for infrastructure and heavy industry projects.
• Customizable upgrade: Variable frequency control, automatic rope arranging device, load weighing sensor, marine waterproof version available.

• Construction engineering: High-rise building material lifting, formwork and steel structure installation & disassembly.
• Bridge & road projects: Prefabricated beam hoisting, bridge pier construction, cable tension traction, tunnel material transportation.
• Metallurgy & steel mills: Steel coil, steel ingot, heavy plate horizontal dragging and vertical lifting.
• Mining industry: Underground raw ore hauling, mine equipment installation and derrick lifting.
• Port & dock terminals: Cargo ship mooring, heavy machinery loading/unloading, floating platform positioning traction.
• Shipyard & marine engineering: Hull block hoisting, ship repair equipment traction, offshore platform module assembly.
• Factory heavy installation: Large machine tools, transformers, generator unit hoisting and positioning.
