Présentation du produit

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.

Types of Electric Winch Machines

(1) According to the driving method

Electric winches: driven by electric motors, suitable for fixed or mobile cranes (such as tower cranes, bridge cranes).
Hydraulic winches: driven by hydraulic motors, strong impact resistance, suitable for heavy cranes (such as crawler cranes, ship cranes).
Manual winches: manually operated, used for small lifting or rescue scenarios.

(2) According to the purpose

Main hoisting winches: responsible for the main lifting operations (such as the lifting and lowering of the spreader of the container shore bridge).
Secondary hoisting winches: auxiliary lifting (e.g., secondary hook control of double hook cranes).
Luffing winch: to adjust the crane boom angle (such as a gantry crane luffing mechanism).
Traction winches: for horizontal pulling (such as cable cranes, running car towing).

(3) According to the structure

Single drum winch: single rope winding, suitable for light lifting.
Double drum winch: double rope synchronization or independent control, to improve stability (such as large tower cranes).

Composition of the Electric Winch Machine

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.

Application

A winch is a device for lifting and hauling heavy loads by winding wire rope or chain, which is widely used in many industries such as construction, mining and shipbuilding.

Cable Laying: In cable laying, heavy duty electric winch machines are used to drag cables through underground pipes or trenches.
Slipway Winch: A slipway winch is a piece of equipment designed to help launch a vessel into and out of the water. It is usually fixed to a ramp and attached to the ship's hull using strong steel cables, which are pulled by a winch to enable the ship to move smoothly along the slipway.
Hydro Power Station: In hydro power stations, electric winch machines are used for maintenance and overhaul work, such as opening and closing heavy gates or lifting turbine components.
Construction: On construction sites, electric winch machines are often used to vertically transport building materials such as bricks, concrete, etc., as well as to assist tower cranes in the assembly of large components.
Pile Driver: A heavy duty electric winch can be used in conjunction with a pile hammer to drive piles into the ground by lifting and releasing the hammer.
Mining Area: In mining areas, electric winches are used for lifting ore and waste rock due to their powerful hauling capacity, or as auxiliary equipment to help move other heavy machinery into position.
Shipyard: In the shipbuilding process, winche machines are used to assemble large ship segments, to adjust the position of components and to take part in the preparatory work before and after the launching of the ship.
Port: In port logistics, electric winches are used in conjunction with container gates for stacking and transferring containers, helping to improve cargo handling efficiency.
