Which of the following is a type of hoisting equipment?

An electric hoist is classified as a type of hoisting equipment because it is specifically designed to lift and lower heavy loads using electrical power. This equipment typically consists of a motor that drives a set of gears, which in turn moves a hook or lifting mechanism to raise or lower objects. Electric hoists are commonly used in construction, manufacturing, and warehousing to safely and efficiently manage heavy items, making them integral to various lifting operations.

In contrast, while pneumatic conveyors are used for moving materials, they operate through air pressure and are not designed for vertical lifting of heavy loads like hoists. Hand trucks are manual devices used for transporting materials over short distances, primarily in a horizontal orientation rather than lifting. Scissor lifts are a type of elevating platform that can move vertically but are not classified as hoisting equipment since they do not lift items individually in the same way a hoist does. Thus, the electric hoist is the only option that fits the category of dedicated hoisting equipment.
