ABSTRACT:
A combined bumper and hoist for use on a vehicle has an elongate housing that mounts transversely across the end of the vehicle as a bumper. A hoist having a mast and a boom is pivotally mounted in the housing for movement between a stored position collapsed into the housing and a raised position with the mast upright and the boom projecting laterally from the mast. The raising of the hoist simultaneously lowers two legs from the bumper to support the bumper on the ground. All of the hoist functions, including raising the hoist to the use position, rotating the mast about its axis and raising and lowering the boom are performed hydraulically. The boom may be equipped with various accessories, including a chain hook and a jib carrying a cherry picker bucket.
