Boat lift |
摘要 |
The pontoon boat lift system comprises a plurality of lifts. Each lift is comprised of a channel that mounts to deck support members of the boat. A leg is pivotally mounted to one end of the channel. A screw supported in the channel is turned by a connection to an electric motor. A threaded follower on the screw travels along the screw when it is rotated by the motor. A fulcrum arm connects between the threaded follower and the leg to transmit a longitudinal movement of the follower into a pivotal movement of the leg. The leg is thus moveable between a raised and a lowered position. The operation of the lifts is coordinated to raise the pontoon boat above the surface of the water at desired shoreline locations.
