发明名称 Length-adjustable chain mount and storage apparatus
摘要 A length-adjustable chain mount and storage box apparatus is mounted to a vertically-movable support structure of a vehicle and arranged so that only a selected outer end length portion of a lift chain need to be pulled from the confines of a storage box whereupon the lift chain is supportingly secured at the selected extended length for connection of its free end to a load to be lifted by operation of the vertically movable structure of the vehicle. When the lifting operation is completed and the lift chain disconnected from the load, the extended portion of the lift chain is simply trained back into the storage box where it is stored without any interference to the normal operation of the vehicle and ready for immediate use when another lifting operation is required.
