Abstract

Abstract This disclosure relates to a worktable for use in supporting damaged automobile body parts while they are being repaired in an automobile body shop. The worktable includes parallel workpiece support arms which are disposed above a frame having horizontal upper and lower platforms separated by vertical spacing members. Various automobile body parts may be clamped to the support arms, thereby permitting a workman access to the entire workpiece. The frame is mounted on caster means which permit the worktable to be moved about the body shop. In order to provide a rigid workbench, the frame member has adjustable legs and a ratchet mechanism to selectively raise and lower the worktable frame so that the castor means can be disengaged from the shop floor when desired.
