Hydraulically controlled mobile warehousing machine - has retractable members in base to clear lifting forks, when in lowest position

摘要

The fork-lift truck, mounted on a wheeled frame, has a mast (4) against which a load carrying assembly, (5,6,7) can be raised and lowered. This is operated from a driving seat (3) behind the mast. When stationary, the lifting forks (6) of the load handling system can be used for shelf stacking. The part under the driving seat is mounted on wheels (2), and an extension at the front has a cross member (8) also mounted on wheels. For stacking operations, either of the side members (10,11), connecting the cross member to the rear part, can be released at one end and swung into a retraction position parallel to the cross member. Each side member incorporates a stepping motor (23) controlling this movement. The release system for these members includes a vertically sliding locking bar (21,22) for each.
