Lift truck load-handling attachment having vertically-slidable quick- disconnect hook

摘要

A lift truck load handling attachment having a quick- disconnect hook assembly for quick mounting or demounting of the attachment on a lift truck carriage. The hook assembly comprises a hook mounting member fastened to the rearwardly-facing surface of the frame of the load- handling attachment, slideably mounting an upwardly-facing hook for vertical reciprocation of the hook relative to the mounting member. The hook and mounting member respectively have elongate, vertically- oriented interlocking slides for permitting such vertical reciprocation while preventing rearward movement of the hook relative to the mounting member. A locking pin is selectively insertable transversely to limit downward movement of the hook relative to the mounting member, and the vertical slides and pin are located below the engagement surface of the hook when in its engaged position so as to permit direct abutment between the front of the lift truck carriage and rear of the attachment frame. The hook is further selectively lockable by the pin so as to limit upward movement of the hook in a lower position so that the hook can serve as a pedestal. The hook mounting member is adjustable for permitting variation of the height of both the hook and the mounting member relative to the attachment frame.
