Hoists are tools that enable the lifting of heavy loads. Hoists are devices used for raising or lowering a load either by a drum or other lifting device around which the chain or rope is wrapped. In some cases it can use either wire or rope as its lifting material and can be manually operated, either pneumatically or electrically driven. Hoists are used in a wide variety of industrial applications from the automotive industry to the building trade to forklifts. There are many different types of hoists and the type that you require will depend on the application.
Chain hoists are used when the task needs to lift a load directly off the ground, either to work on it or move it along. A common use for this type of lifting capacity is on forklifts. There are several different types of chain hoists available depending on their design. The kind of lifting capacity they can handle will also depend on the chain length and the cross section. The longer the chain and the straighter the configuration, the lower the lifting capacity will be.
Hooked hoists can be fitted onto forks to lift loads that have been lowered by the forklifts' hydraulic system. They are operated via an electric motor and there is a control switch that lets the operator to decide how high to raise the hoist. In some cases a forklift can move the load using only its own power, but this requires manual operation because it has to support the weight of the load and the angle of the lift. Some hooked hoists are operated electronically. This is a good design because it is less expensive to build and requires less maintenance.
Overhead hydraulic hoists, also known as scissor lifts are a type of mechanical lifting that enables the user to raise floors or ceilings using only the power of the crane. Unlike the vertical and forklift versions, overhead hydraulic hoists have a limited lifting capacity. However, many buildings need to be raised using them, mainly because they cannot be fitted with counterweights. This type of hoists has a hydraulic cylinder that is mounted on a metal frame.

All these types of hoists use mechanical action to raise or lower a load. Sometimes the lifting action is provided by counterweights, and sometimes by counter-weights and chains. Hoists that use counterweights are usually more stable than ones that use chains. However, you need to make sure that the hoists you consider having sufficient capacity for your load.
Another important consideration is whether the building needs a power source to operate the hoists. There are three main types of powered hoists: electric chain hoists, gas powered ones and line material powered hoists. If the building does not have a power source, then the last option available is line material powered hoists.
