Abstract

An vehicle body framing apparatus and method for use in assembling vehicle body structures of varying vehicle types in a framing station positioned along an assembly line. The apparatus includes an overhead bridge frame that is connected to two pairs of vertical pillars positioned at a build station. One pair of the pillars is moveable to accommodate different lengths of vehicle bodies. The spaced pillars and overhead bridge provide substantially unobstructed access openings to the body sides of the vehicle to increase efficiency and quality of build. The device and method may include a bridge frame storage and transport system for remotely storing the different bridge frames not in use and then transporting a selected bridge frame to the build station for use.
