Abstract
This invention relates to a retention device (30) for releasably maintaining a load engaging member (24) at a transport position (28) which eliminates the problems of supporting and simultaneously locking the load engaging member (24) at the transport position (28), failure of the lock device due to the weight of the load engaging member acting thereon, and alignment of the load engaging member (24) with the locking device. The retention device (30) has a stop (66) connected to the load engaging member (24) and a flange (40) engageable by the stop (66) at the transport portion of the load engaging member (24), to support the load engaging member (24) and the weight thereof at the transport position (28). The retention device (30) also has an engaging device (74) which engages the stop (66) and prevents pivotal movement of the load engaging member (24) from the transport position (28) to a load carrying position (26). Thus the problems of failure, alignment and support of the load engaging member (24) are eliminated. The retention device (30) is particularly suited for retaining the fork (24) of a carriage assembly (20) of a lift mast (12) at the transport position (28).
