Abstract
A portable low-profile tipper for dumping the contents from a trailer containing a dumpable material, includes a towable elongated and angled frame having a portion resting on the ground during dumping for greater stability. A deck is pivotally attached at an elevated position to the frame back end. The deck has a backstop for positioning the trailer during dumping. Actuators raise and lower the deck to dump the trailer contents. The tipper has a chute with fixed and pivoting components cooperating to guide the dumpable material from the trailer past the frame back end. Front and back stabilizers extend outwardly from the frame. The front stabilizers lift and lower the frame front end between a low-profile dumping position and a raised towing position. A method of successively removing the contents from a plurality of trailers using the tipper is also provided.
