Abstract:
1. A watercraft vehicle lift, comprising: a pivoting hinge configured to rotate around a fixed axis; a hydraulic lift configured to extend and contract an arm to apply force at an acute angle, wherein the acute angle is based on a floor of a body of water; a scissor hinge with a plurality of pivoting points configured to extend and contract, a first of the plurality of pivoting points being positioned below a water level, and the first of the plurality of pivoting points being configured to receive the applied force from the arm of the hydraulic lift at the acute angle below the water level, wherein responsive to the arm being contracted the arm decreases in length and directly pulls the first of the plurality of pivoting points, wherein a second one of the plurality of pivoting points is coupled to a base of the watercraft vehicle lift, wherein the base extends from a point below the pivoting hinge to the second one of the plurality of pivoting points; a bunk beam coupled with the scissor hinge at a first portion via a third of the plurality of pivoting points and coupled with the pivoting hinge at a second portion, wherein responsive to the scissor hinge receiving the force from the arm of the hydraulic lift at the acute angle a first side of the bunk beam is configured to be raised or lowered, and responsive to the arm being contracted and decreasing in length directly pulling the first of the plurality of pivoting points the bunk beam is configured to be lowered to be positioned in a downward angle, wherein when the arm of the hydraulic lift is contracted then the first of the plurality of pivoting points is positioned between the hydraulic lift and the second and third of the plurality of pivoting points.
