The lift winch is a device that drives the drum and winds the rope by manpower or mechanical power to complete the traction work. It can be lifted vertically, pulled horizontally or tilted to lift heavy objects.
It is widely used in material lifting or flat dragging in construction, water conservancy projects, forestry, mines, wharfs, etc. It can also be used as supporting equipment for modern electric control automatic operation lines.
The electrical winch can be used alone, or it can be combined with other cranes to form a large and complex hoisting machine. This machine has strong versatility. In addition to being widely used for hoisting in material lifting and large hoisting projects, it can also drag various materials and equipment on slopes or flat ground.
In addition to being widely used in construction sites, equipment installation, etc., lift winch is also widely used in metallurgy, mining, hydro-power, agriculture, military, chemical and transportation industries, such as the lifting of blast furnace bells and materials, the lifting of mine materials, the horizontal and inclined traction transportation, the dispatch of mine carts, the return of pillars, the lifting of anchor chains on ships, etc.
The lift winch mainly has the following uses
1. Lift heavy objects
A certain speed is required to increase productivity, and high safety is required to prevent falling.
2. Equipment installation
Generally speaking, the quality of the equipment is relatively large, which requires the hoist to have a large lifting capacity; in order to ensure the installation accuracy, its speed cannot be too high; in order to prevent falling, its safety requirements are higher.
3. Pull items
Because this work is generally carried out in the horizontal and inclined directions, in order to make the items move back and forth, it is required that the lift winch drum can work both forward and reverse.
4. Piling
After the electric winch is required to lift the heavy object to a certain height, it can make the heavy object fall into a free fall and realize the piling work, that is, the hoist is required to have the performance of slipping.
