Alum-A-Vator is a traditional shafted beam boat lift, specifically engineered to withstand harsh conditions. Recognizable by its eight sided heavy-duty aluminum cast cover, Alum-A-Vator is the choice for the discriminating homeowner and for any marina or commercial installation where reliability and durability are a must. All structural parts are manufactured from high strength corrosion resistant 6061-T6 aluminum and the lift is driven by stainless steel motors. Bunks are fully carpeted.
