Lifting equipment – an indispensable tool for work associated with lifting different weight loads. One such device is a winch. It is a mechanism designed to move a variety of treasure, cargo, and other heavy things with the help of a movable flexible element, which may be a rope, chain or cable.

In the days of the slaves in Egypt and Rome used the winch. Through the mechanism of the Egyptians could quickly raise and move the necessary things, only the action of the winch was operated by the muscular or animal force. Today, winches for special equipment to function on a mechanical drive and is indispensable in the construction, installation and other works. The device can move loads in horizontal and vertical direction.

The types of winches.
The variety of mobile structures based on different types of actuators and gearboxes, which lead them into action. Structurally, the unit includes:

1. Body, it can also be frame;
2. The drum intended for winding cable or chain;
3. Reducer;
4. Brake;
5. Driving device.

The type of actuator designs are available with manual mechanism or electric. Manual involve the movement of goods with the use of physical force, but it has one important advantage – ability to work without access to mains power. It expands the sphere of its application. Units with electric drive are powered by an electric motor. It is more complicated mechanisms, but their use will depend on the availability of the power supply.

Mechanical hand winch are:

• Worm;
• Chain;
• Construction drum;
• The device lever.

The winch, which works off of the actuator, actuates a drum with the motor by means of reducer. The components of this unit are:

• Switchgear. It is used to protect and control motors.
  
• Switches and circuit breakers.
  
• Management button post.
  

The functions of winches.
Manual mechanisms and structures with electric actuator are widely used for transportation of different goods. Functionally they can be divided into several groups:

• Traction. They are used for movement and for lifting loads of varying severity;
• Shunting. Apply for displacement of the carriages located in the warehouses;
• Drilling rigs or support structures. Use for lifting equipment in drilling area. They also work with casing pipes;
• Scraper. Designed for the movement of parts of rocks to extract minerals.

Mechanical and manual hoist are indispensable during construction and installation works in other areas. It is easy to use, convenient, high load capacity, durability will serve for many years.
