The term 'tilting truck' can be summarized as a dumper, which is a six-letter word. A tilting truck is a type of vehicle that is used to transport materials such as dirt, gravel, and other debris. It is designed with a tiltable bed that can be raised or lowered to allow the material to be dumped out. The truck is typically powered by an internal combustion engine and is equipped with a hydraulic system to control the tilt angle. Tilting trucks are commonly used in construction and mining operations.
