What is a hoist?
- A hoist is a mechanical device, manually, electrically powered, that is used for vertical lifting, lowering or moving an object along a horizontal path.
- Lifting is accomplished when a wire rope or chain winds or unwinds as the hoist drum rotates.
- Hoists are controlled by an overhead crane operator via an attached electrical push button pendant device or can be radio controlled, remotely.
- A wide variety of industries use hoists in their daily business operations, such as Aerospace, Agriculture, Automotive, Computer, Construction, Chemical, Food, Logging, Marine,
- Manufacturing, Medical, Mining, Telecommunication, Transportation, Hospitals, Health care, Entertainment and many others.
There are different types of hoists that come with a variety of options such as lift weight, length of chain, lift speed and its configuration is usually defined by the lifting medium, operation and suspension.
types of hoist:
