Electric winches are motorized pulling machines for moving heavy loads or towing vehicles with less effort than manual winches. Designed for intermittent use, they have a line that attaches to the load and a motor that rotates a drum to wind in the line and draw the load toward the winch. Industry safety standards call for a minimum of five wraps of line around the drum during pulls. Winches maintain their load capacity with up to two full layers of line wrapped on the drum, but capacity decreases with each additional layer. Electric winches rated for pulling are used for horizontal pulling or towing of loads. Electric winches rated for pulling and lifting can pull loads horizontally or lift and lower them vertically. DC winches are typically powered by a vehicle battery. AC winches plug into an electrical outlet for power.
An electric winch, a light and small lifting device that is used to wind or wind a wire rope or chain to lift or pull heavy objects, also known as a winch. The hoist can lift, level or tilt the weight vertically. The winch is divided into three types: manual winch, electric winch and hydraulic winch. Nowadays, the electric winch is the main one. It can be used alone or as a component in machinery such as lifting, road construction and mine lifting. It is widely used due to its simple operation, large rope winding and convenient displacement. It is mainly used for lifting or flattening of materials such as construction, water conservancy projects, forestry, mines, and docks.
1. The diameter is reduced; the diameter wear exceeds 40% should be scrapped, and no more than 40% should be used to reduce the coefficient.
2. Surface corrosion; when the surface of the whole wire rope is corroded to the naked eye, the wire rope cannot be used.
3. structural damage; wire rope breakage should be scrapped, wire rope with broken wire should be used to reduce the coefficient.
4. overload; overloaded wire ropes must not be used.
