  • Patent number: 7707955
    Abstract: A lifting apparatus includes a lift arm for carrying a platform or cradle and is pivotally attached to a base for movement between lowered and raised positions. A crank arm is pivotal with the base and a connector arm is pivotal with the lift arm. The crank arm and connector arm are pivotally connected to each other for rotation about a common pivot axis. Rotation of the crank arm by an actuator moves the crank arm and connector arm combination through a top dead center alignment a lowered over center alignment with the lift arm movable from the lowered position to the raised position during operating positions of the apparatus, and to a raised over center alignments with limited movement of the lift arm in the raised position for providing a locking position of the apparatus thus eliminating a need for typical additional locking mechanism.

  • Patent number: 7637690
    Abstract: A programmable boatlift system having a cable extending up from one end of a boatlift cradle, across through a shaft attached to a motor, and down to an opposite end of the boatlift cradle. A position sensor having an idler sheave is placed on the cable, or a position sensor having a collar is placed on the shaft. The motor turns the shaft to cause the cable to move across the roller sheave, or to cause the collar to rotate, to raise or lower the boatlift cradle. The position sensor produces an output signal proportional to the distance the cable travels over the idler sheave or proportional to the number of rotations of the collar. An electronic control circuit uses the output signal to infer the vertical position of the boatlift cradle and to position the boatlift cradle as desired.

  • Patent number: 7618223
    Abstract: A personal transfer device for transferring a boater from a dock to a boat moored in a boat lift adjacent the dock, and back again. A cantilevered support is secured to an upper part of the boat lift frame, the support's free end extending out over the dock at a height that does not interfere with normal use of the dock. A hoist carriage, for example a monorail trolley hoist, is movably secured on the cantilever support, and is connected to a transport chair that can be located over the dock at a convenient height for a handicapped boater to seat and/or secure himself. A controller is accessible to the boater seated in the transport chair to raise himself off the dock to a height sufficient to clear any intervening boat lift structures or frame members, and to then transport himself horizontally along the support through the boat lift structure to the boat, where he then lowers himself onto the boat using the controller.

  • Patent number: 7536965
    Abstract: An attachment for use with a boat lift that both lifts the watercraft out of the water and allows horizontal movement of the watercraft to a position over a dock. The apparatus provides a vertical extension to the central mast of the lift apparatus. A horizontal arm attached to the distal end of the vertical extension provides an attachment point for a cable, which may be connected to the watercraft while still afloat. Raising the mast raises the suspended watercraft above the water while a cradle assembly upon which the hull of the watercraft normally rests is disposed a predetermined distance below the hull. Once the hull is raised above the dock, the vertical mast rotates to position the watercraft over the dock. The cradle is positioned underneath the dock. The watercraft may be lowered onto the dock with no intermediate structure between the hull and the dock surface.
