An air hoist is a type of lifting equipment that uses compressed air to lift and move heavy loads. It consists of a motor, which is powered by compressed air, and a chain or cable attached to a lifting hook or other load-bearing attachment. The air hoist is typically mounted on an overhead crane or other support structure, and can be controlled manually or through a remote control device. Air hoists are used in a variety of industrial and commercial applications, including manufacturing, construction, and transportation, where heavy loads need to be lifted and moved quickly and efficiently. They are known for their high lifting capacity, precise control, and reliability, and are often preferred over other types of hoists because they do not produce sparks or generate heat, making them safer to use in hazardous environments.
