Title: Dump trailer
Inventor: STEWART LARRY L
IPC: B60P1/30
Filed: 2011-02-25
Abstract: A towable dump trailer is provided. The towable dump trailer comprises a first, second and third frame. The first frame comprises one or more sets of wheels. The second frame is attached to the tow vehicle and can be displaced horizontally relative to the first frame by the towing vehicle moving rearward or forward.
