Hoists are very necessary in the world of construction and mining. In construction, hoists are used to lift personnel, materials, and equipment to a higher level.
Without this device, the construction of high-rise buildings will be difficult! In mining, hoists are used for transporting up and down mining shafts.
The important thing to know here is that hoists are made in two forms: package units and special built-up units. The package unit, as indicated by the name, is made as an integral package. This is not versatile, but can handle relatively heavier loads.
Special units, on the other hand, are made of a number of individual parts that can be put together as and if needed. It was originally known to have smaller load capabilities, but the latest models have been made to carry a heavier load too.
