Abstract
A battery-powered lift assembly includes a lift and a cam mounted to a vehicle hitch. The cam defines a substantially vertical finger notch and an angled finger notch. A biased folding bracket is pivotally coupled with the cam. A pallet is pivotally coupled with the lift and a cam follower is mounted to the pallet in a position to cooperatively interact with the folding bracket. When a load is on the pallet, the folding bracket yields to the cam follower permitting it to enter the substantially vertical finger notch and the pallet remains in a substantially horizontal position as the fill moves from a lowered position to a raised position. Without a load, the folding bracket directs the cam follower into the angled finger notch, which caused the pallet to pivot into a substantially vertical position. In this position, the cam may he tilted away from the vehicle hitch.
