When you see a cylinder wrapped around the line on the construction site, do you know what it is? It is called a winch and is an important tool in construction engineering. It helps people solve many weight problems. Today, we will learn more about the winch.Winch definition
The winch is a lightweight lifting device. Winding a wire rope or chain with a reel to lift or pull heavy objects. The winch is a component that can be used alone or as a component in lifting, road construction and mine lifting. It is widely used because of its simple operation, large rope winding and convenient displacement. It is mainly used for lifting or flattening of materials in construction, water conservancy projects, forestry, mines, docks, etc.
According to the power, the winch is divided into three categories: pneumatic, manual, electric and hydraulic.
According to the function, the winch can be divided into: marine winch, engineering winch, mining winch, cable winch and so on.
Today we mainly introduce the following types of winches:
Electric winches are widely used in places where work is heavy and where traction is required. The motor of the single-roller electric winch drives the reel through the reducer, and a brake is arranged between the motor and the input shaft of the reducer. In order to meet the needs of lifting, traction and turning operations, there are also winches for double reels and multi-roll units.
Example of winch designed for wakeboarding. These winches consist of a small four-cycle gasoline engine, clutch, and spool all housed inside of a steel frame. A rider is towed rapidly toward the winch as the rope winds around the spool.This is a vertical spool with a ratchet mechanism similar to a conventional winch, but with no crank handle or other form of drive. They are used on small sailing boats and dinghies to control sheets and other lines, and in larger applications to supplement and relieve tension on the primary winch mechanisms.
Wakeskate winching is a growing hobby for many water sports enthusiasts. The winch consists of an engine, spool, rope, handle, frame, and some sort of simple transmission. When the winch is engaged, it pulls the boarder usually between 15 to 25 miles per hour . The winch may be mounted on the trailer hitch of a vehicle, set into the ground by stakes, or tied to a tree. These winches have been modified for use by skiers and snowboarders in cities.
An air winch, sometimes known as an air hoist or air tugger, is an air-powered version of a winch. It is commonly used for the lifting and the suspension of materials. In the oil and gas, construction, and maritime industries, air winches are frequently preferred to electric, diesel, and hydraulic winches because of their durability, versatility, and safety.
