Abstract:
The objective of the present invention is to provide a boat lift capable of lifting and lowering a boat even with fewer power sources, thereby having high price competitiveness, and the present invention relates to a boat lift for lifting and lowering a boat between a lifted state in which the boat is spaced upward from a water surface and a lowered state in which the boat is lowered therefrom, the boat lift comprising: a pair of buoyancy units arranged in parallel with a predetermined boat space interposed therebetween; a plurality of cross bars connected to each other across the boat space so as to support the boat from the lower part thereof; lifting and lowering pulleys provided at the cross bars; fixed pulleys provided at the buoyancy units; a weight; a linear link member, which has a fixed end fixed to the buoyancy unit and a lifting and lowering end from which the weight is hung, and passes through the lifting and lowering pulleys and the fixed pulleys from the fixed end so as to be connected to the lifting and lowering end; and a driving part for lifting and lowering the cross bars. Therefore, a large weight can be lifted and lowered even with fewer power sources by means of a combination of the lifting and lowering pulleys, the fixed pulleys, and the weight.
