Overhead hoists are increasing in popularity. The hoist unit hangs from a track that is securely attached to the ceiling. The client is suspended in a sling from the hoist unit and moved along the length of the track. Although the over head can only be used where there is track it is particularly useful in places where it would be awkward to wheel a mobile. Track configurations can be anything from a straight run, through complex arrangements with bends and turn tables, to the XY system which allows complete coverage of a room, such as a hospital ward.
