Abstract
A versatile mobile high lift loader characterized by an extendible telescopic boom carried by a longitudinally extendible transfer carriage. The transfer carriage travels on stepped fore and aft longitudinal transfer rails for greater operator visibility. The transfer rails are stepped laterally to provide for maximum width of the operator compartment and to permit the use of dual front wheels. The transfer carriage and boom extension travel on cam roller non-friction bearings for cycling demands of the fork lift transferring boom. The transfer rails include readily replaceable hardened wear surfaces on a unitized frame. The loader includes modular drive train fabrication for less expensive manufacturing cost and easier servicing. It is provided with drive line disc brakes and locking differential for easy servicing, non-power assist and positive braking with and without load. The telescoping boom includes a novel hose reel assembly for transfer of internal hosing within the boom. The telescoping boom segments travel on readily replaceable hardened rails that also serve to give outer fiber strength and buckling resistance. The boom may be fitted with a fork lift or crane hook or similar work performing means, dependent upon need. The load handling mechanism can be retracted behind the front wheels for close approach to buildings. Load transfer is by pure horizontal motion.
