BOAT LIFT

摘要

A floating boat lift having flotation tanks positioned under sides of a frame of the boat lift. Water flow is regulated so that tanks fill from near the center of the boat lift. A preferred hingeable connection of the boat lift to a bulkhead, along with lateral stabilization, participates in maintaining a generally horizontal attitude for the boat lift. Water is accepted into or pumped from the flotation tanks, allowing the frame of the boat lift to fall or rise relative to the surface of the water. One or more catwalks along the sides of the boat lift and connected to the bulkhead may float, but at a level that is independent of the boat lift frame.

1. A boat lift, comprising:
a boat lift frame constructed and arranged to receive a boat hull on an upper surface thereof, the boat lift frame comprising;
a transverse flotation tank positioned under a first side of the boat lift frame;a first flotation tank that joins the transverse flotation tank at an end of the first flotation tank;a second flotation tank that joins the transverse floatation tank at an end of the second flotation tank and opposite the first flotation tank;a third flotation tank that joins the transverse floatation tank at an end of the third flotation tank; anda fourth flotation tank that joins the transverse floatation tank at an end of the fourth flotation tank and opposite the third flotation tank; wherein the first flotation tank is spaced apart from and is generally parallel with the third flotation tank; the transverse flotation tank being in hydraulic communication with the first flotation tank, the second flotation tank, the third flotation tank and the fourth flotation tank.
