Boat lift transport apparatus

A boat lift assembly, comprising:

• a base having sides;
• a boat support frame;
• a parallel linkage pivotally mounted to the base at first ends thereof and to the boat support frame at second ends thereof, and pivotable to move the boat support frame between a lowered position and a raised position spaced from the lowered position in a vertical direction;
• at least one float roller having an axle extending generally across said base;
• a pivoting mounting arm for supporting the boat support frame relative to the base;
• an actuator for moving said float roller comprising a pair of pulley members, one mountable on each of the sides of said base, a pair of cable portions, one cable portion on each side of the base supported on a respective pulley member, and a coupling to couple the cable portions to opposite ends of the axle of the at least one float roller, respectively, the cable portions being on the respective pulley member and being secured relative to the boat support frame and being of length such that as the boat support frame moves in a selected direction between the lowered and raised positions, the cable portions move through the pulleys and pull the axle and the at least one float roller downwardly to float the boat lift assembly;
• and
• an actuator for moving the boat support frame between its lowered and its raised positions.

A boat lift assembly, comprising:

• a base;
• a boat support frame having a length and a width and being configured to support a boat thereon;
• movable supports for mounting the boat support frame relative to the base for guiding movement of the boat support frame from a lowered position to a raised position spaced from the lowered position in a vertical direction;
• at least one float roller having an axle extending laterally across the width of the boat support frame;
• and
• the float roller and axle being selectively coupled to the boat lift assembly to move vertically downwardly to provide a floating support for the boat lift assembly as the boat support frame is moved from one of its positions to the other position.
