Abstract
A system and method of raising and lowering a ball hitch for coupling to a gooseneck trailer coupler are provided. A combination of hydraulic pump and hydraulic piston are employed to raise and lower the ball hitch. Both custom and off the shelf parts combine to create a user friendly system to couple and uncouple a gooseneck trailer to the truck. The system described herein replaces the need to raise and lower a gooseneck trailer by hand crank and gear box. A non-rotating free end hydraulic piston device extends and retracts to raise and lower the ball hitch in both coupling and uncoupling of the trailer.
Claims41
A hydraulic flatbed ball hitch lift device, the device comprising:
- a cylinder mounting ring;
- a hydraulic cylinder secured to the cylinder mounting ring;
