Among the heavy load machines, the hoist or rig is one of the most used for suspended lifting and vertical displacement of material or materials to be mobilized with less effort than if we had to move the load by hand.


Featured hoist types

  • Manual
  • Electric
  • Cable
  • Chain
  • Lever
  • Factorial
  • Differential
  • Potential

What is the hoist?

The hoist or rig is a machine composed of a system of fixed and mobile pulleys that allow to lift a load exerting a smaller force to the weight that has to be moved. The use of the pulleys minimizes the effort required to move the load. They can have different sizes or lifting powers. The small ones are manipulated manually, and the larger ones have an electric motor incorporated to make them work. Depending on the load to be loaded or unloaded there are many types of hoists. Some are electric, others use manual force or levers to exert their power with chains, cables, branches, hooks, clamps, magnets and other accessories with similar characteristics.

Hoists perform mechanical work because it allows a force to act on a body to move it at a certain distance.

The term hoist has its origin in the Greek word “polys” which means “a lot” or “abundant” and grass which refers to the act of “pulling” or “pulling”.

What’s the hoist for?

Hoists are used in industries, workshops or construction areas to load and unload heavy materials to be placed in transport trucks, ships or fixed spaces.

The hoist enables this task to be carried out without difficulty, quickly and efficiently.

Its capacity to lift loads can vary depending on the number of branches used. For this reason, it is pertinent to verify the load weight that will be lifted and determine the most appropriate lifting equipment to hoist and move the load.

In some rescue cases, hoists are used to lift injured people who have fallen into cracks or deep spaces.

Types of hoists

In the market for loading machinery, there are many types of hoists. It is important to know the types and their characteristics in order to know which one is best suited to the task to be accomplished with this type of machine.

The hoists or rigs can be typified according to:

Below are different types of hoists or hoists.

Electric hoist

This type is designed according to the same operating principles as the hand hoist. In this case, an electric control replaces the chain drive. The electric control of this hoist allows lifting and lowering objects quickly or slowly.

Manual hoist

The chain hoist is manually operated, and its compact and lightweight design allows a load capacity of up to 2 tons. This tool is ideal for vertical lifting of the load to be moved.

The manuals are made up of a pulley system that allows the heavy load to be lifted with less vertical effort. In this type of hoists, the power to lift objects comes from the person who uses this device. Installation is usually very simple.


Allows the horizontal and vertical movement of heavy weights with precision and safety. It is used in many industries for deposit, storage or material transfer.

The hoist crane has a double structure in which two auto motors act allowing the sliding and railing process production.

This type is operated from a remote cabin.

By car

Trolley hoists can be manual or electric. In addition to the vertical lifting, they allow the horizontal displacement of the load.
