Patented design (U.S. Patent 6,470,816) allows the motors to be placed on the shore side for easy maintenance and leveling from bow to stern for easy draining. GatorVator™ Lift Capacity 2,000 lbs 4,000 lbs 7,000 lbs 10,000 lbs 14,000 lbs 16,000 lbs 20,000 lbs 24,000 lbs 30,000 lbs The 2,000 lbs and 4,000 lbs capacity lifts are a one motor, 3 piling lift setup with no upper beams. The 7,000 lbs, 10,000 lbs and 14,000 lbs capacity lifts are 2 motors and are either a 3 piling or a 4 piling configuration. This is the best boat lift design for many reasons:The GatorVator™ lift requires only two drive spools. They are 3-1/2″ diameter and grooved for the longest cable life possible; the cables never wrap over the top of each other. These lifts have less cable than all other lifts with or without top beams; no electric wires run under the water and the lifting speed is 33% faster. This design has eliminated the common objections of the top beam of a lift being unsightly and boarding a difficulty. This clean look and easy maintenance makes it a sure winner. It is adaptable to boat houses, existing pilings, and other structures. The GatorVator™ is user and installer friendly!
