WEIGHT DISTRIBUTING HITCH ASSEMBLY |
摘要 |
A weight distributing hitch assembly includes a shank, hitch head, spring ba r and lift assembly. The lift assembly is preferably removable mountable to the frame members of a trailer frame while the spring bar extends below the frame members relative to the ground. The lift assembly mounts a hanger assembly which engages a cantilevered segment of the spring bar to drive the spring bar from a free state to a loaded state to distribute the hitch load to a towing vehicle as well as to the trailer. A lever assembly mounts the hanger assembly to the lift assembly and supplies mechanical advantage to assist a user during tensioning of the spring bar. By moving the lever assembly, the cam rotates about a pivot. As the hanger assembly is engaged with the cam, the hanger assembly is driven from a disengaged position to an engaged position which moves the spring bar from its free state to its loaded state with a minimum of user effort.
