Air-hoists function using air pressure to provide the force necessary to lift a load. While electric hoists depend on the power of an electric motor to move the load from one place to another, air hoists use differentiating air pressure to produce enough lift to move heavy objects.
How does a hoist work?
A chain hoist is operated by hand. An operator will pull down on one of the chain loops on one side of the chain. This will turn a pulley mechanism inside the chain hoist housing. When this pulley turns, it will lift up the end of the other chain which usually has a hook on the end.
What are the different types of hoists?

What is the difference between a hoist and a lift in construction? … In simple terms, a hoist is a construction device that typically uses a pulley system to raise objects upward while a construction lift typically includes an aerial platform maintained by a specific form of extension and fitted on a vehicle.
Which motor is used in hoist?
While PMDC motors are used in hoist, reel and winch applications up to 10 HP, wound field DC motors 14 are commonly used in industrial applications above this range and up to several hundred horsepower (HP), in both the standard and explosion proof types.
What is the difference between a hoist and a winch?
A winch is designed to pull a heavy load horizontally over a slightly inclined or level surface, and a hoist is designed to lift a load vertically over steeper inclines that are greater than 45 degrees. Both tools can make heavy lifting tasks easier.
Can you use a hoist without training?
never use a hoist that they have not been trained to use. always ensure that the right hoist is being used for the job — if in doubt, staff should be trained not to use the hoist but to reassess the handling operation. never exceed the safe working load of the hoist.
Why is it unsafe for only 1 person to use a mobile hoist?
Some hoist systems actually require two people to use them because of the way that they operate – this is particularly common for older equipment. In this case, these hoists are moved manually and therefore require somebody to operate the hoist, as well as somebody to actually help the patient move.
What can go wrong when hoisting a person?
