LiftBar™ is the first boat lift to incorporate a screw jack-based lifting mechanism fully within an aluminum tube to deliver a hidden structure, no sway, higher speeds, increased reliability and enhanced submergibility. Because of its contained design, the lift is submersible which enables it to be installed out of sight at dock level and provides peace-of-mind in extreme environments. The powerful 6hp motor provides speeds multiple times faster than traditional 220v motor lifts with gearboxes and the inline motor with planetary gears delivers a much quieter lifting and lowering experience. The universal design attaches to pilings, fixed docks, and integrates into floating docks.
