The 8,500 lb. Advanced Flat Plate Boat Lift Hoist combines a 1 1/2 HP wired motor and an 8,500 lb. gear plate assembly to create a boat hoist. The hoist features no steel-on-steel moving parts. The hoist uses bronze-on-steel gearing. A 96-tooth bronze worm gear on a hardened steel worm. The hoist uses a solid aluminum extended block housing that strengthens and supports the backplate. This reduces heat build-up caused by friction and keeps the worm gear greased and aligned. It allows for a more economical and lighter weight 1/4 in. backplate. The hoist includes actual true backplate bearings, innovative and easy-to-reach zerk grease fittings, enclosed worm housings, aluminum dual belt drive pulleys, dual drive belts, and extended support blocks. Features a dual pulley and drive belt system.
