Abstract
A device which is easily attached to the side of a scaffold for lifting objects up the side of the scaffold. The device consists of a carriage which has a rectangular frame having guide members with wheels attached at each corner for engaging the pipes of the scaffold frame. The wheels are attached such that the carriage can ride up and down on the scaffold without interference with the scaffold frame supports and cross members. The carriage has a motor attached to it which is connected to a chain drive. There is a chain which runs through the chain drive and attaches to the top of the scaffold frame. The motor and chain drive act on the chain to drive the carriage up and down the scaffold. The chain drive preferably has a brake for use when the carriage is stopped. The carriage frame has a means of attaching a pair of forks. The width of the forks are adjustable on the carriage frame.
