Abstract

A device is disclosed for raising, lowering and positioning a pintle eye style detachable gooseneck hitch assembly of a trailer. The gooseneck hitch assembly is connected at its forward end to a pintle hook positioned at the rearward end of the truck. A hydraulic cylinder is pivotally connected at its rearward end to the gooseneck hitch assembly and has a pair of chains secured to its forward rod end with the chains extending forwardly and outwardly therefrom for connection to the rearward end of the truck laterally and above the pintle eye-pintle hook connection. Extension of the rod of the hydraulic cylinder causes the rearward end of the hitch assembly to be lowered relative to the ground. Conversely, retraction of the rod of the hydraulic cylinder causes the rearward end of the hitch assembly to be raised. The hydraulic cylinder permits the hitch assembly to be maneuvered or positioned relative to the trailer when the hitch assembly is being detached from the trailer or being connected thereto.
