Abstract: For transporting and indexing panel wall sections, a wheeled base chassis supports a lateral movable plate, in turn carrying three separate frames for performing the various orienting functions. The innermost frame is pivotally carried by the lateral plate to permit all three frames and the panel load to be tilted rearwardly over the chassis for transport. This frame carries the middle frame to permit it to be driven vertically relative to the innermost frame for fitting the panel into position, as a first portion of the wall or a continuing portion. The middle frame carries the outer frame with it and also mounts it for 45.degree. motion relative to the middle frame to remove the panel from its aligned or home position for the application of adhesive, with the machine returning it exactly for final bonding, the chassis being leveled or tilted by opposed levelers extendable against the floor.
