Abstract
A watercraft lift system for effectively operating in shallow water. The watercraft lift system generally includes a base structure, a plurality of support legs pivotally connected to the base structure, a support platform connected to the support legs, a pair of lifting assemblies connected to the base structure and the support platform, and a pair of actuators connected to the base structure and the lifting assemblies.
Claims20
A watercraft lift, comprising:
- a base structure;
- a watercraft support structure pivotally connected to said base structure, wherein said watercraft support structure is positionable into a lowered position or a raised position, and wherein said watercraft support structure is adapted to receive and support a watercraft;
- a first lifting assembly, wherein said first lifting assembly is pivotally connected at a first pivot point to a first side of said base structure, and wherein said first lifting assembly is connected at a first connection point to said watercraft support structure;
- and
- a first actuator, wherein said first actuator is connected to said base structure and to said first lifting assembly, wherein said first actuator is connected to said first lifting assembly between said first pivot point and said first connection point.

A watercraft lift, comprising:
- a base structure;
- a watercraft support structure pivotally connected to said base structure, wherein said watercraft support structure is positionable into a lowered position or a raised position, and wherein said watercraft support structure is adapted to receive and support a watercraft;
- a first lifting assembly, wherein said first lifting assembly is pivotally connected at a first pivot point to a first side of said base structure, and wherein said first lifting assembly is connected at a first connection point to said watercraft support structure;
- a first actuator, wherein said first actuator is connected to said base structure and to said first lifting assembly, wherein said first actuator is connected to said first lifting assembly between said first pivot point and said first connection point, wherein said first actuator is attached to an outside of said first side of said base structure;
- a second lifting assembly, wherein said second lifting assembly is pivotally connected at a second pivot point to a second side of said base structure, and wherein said second lifting assembly is connected at a second connection point to said watercraft support structure;
- wherein said first lifting assembly and said second lifting assembly are each comprised of an inverted V-shaped structure when said watercraft support structure is in said lowered position;
- and
- a second actuator, wherein said second actuator is connected to said base structure and to said second lifting assembly, wherein said second actuator is connected to said second lifting assembly between said second pivot point and said second connection point, wherein said second actuator is attached to an outside of said second side of said base structure.
