ABSTRACT:
A portable work station suitable for use in a vehicle spray paint booth, the station includes a platform member supported on each end by an open frame end support member. The end members pivot about the end of the platform and can be adjusted so as to change the height of the platform above the work surface. A leg of each end support member is wedged between pin, a stop stud fixed to the end of the platform and a locking pin is pivoted into engagement with the leg to prevent walking motion of the work station while in use. The work station can be provided with a railing along the platform edge, a tool hanger, and can be provided with an air supply stanchion to facilitate the spray paint operation.
