摘要：
A combination ramp and cart device includes a main frame and a pair of wheel support frames mounted thereon. In a ramp configuration the wheel support frames extend upwardly from the main frame and support respective front and back ends of ramp frames, which are removably mounted on the main frame. In a cart configuration the wheel support frames depend downwardly from the main frame and a pair of legs are mounted on the main frame to support same. In a cart configuration of the device, the main frame also mounts a trailer hitch frame. In another aspect of the invention, a hitch-mounted ramp device includes a hitch frame adapted for mounting on a vehicle and a pair of ramps adapted for mounting on the hitch frame.
