Tippers

Dump Semi-trailers 

Dump Semi-trailers ("British" Tippers) are trailers in which one end can be raised to allow the cargo (often building materials or Agricultural produce) to slide out the other end. Commonly, they are hinged at the rear and raised at the front, but side-unloading dump trailers also are used.

The key advantage of a semi end dump is a large payload. A key disadvantage is that they are very unstable when raised in the dumping position limiting their use in many applications where the dumping location is uneven or off level.
