"A dump truck, known also as a dumper truck or tipper truck, is used for transporting materials (such as sand, gravel, or demolition waste) for construction as well as coal. A typical dump truck is equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited ("dumped") on the ground behind the truck at the site of delivery. In the UK, Australia, South Africa and India the term applies to off-road construction plant only, and the road vehicle is known as a tipper lorry (UK, India), tip-truck, tip-trailer, tipper truck, or tipper (Australia, New Zealand, South Africa)." - (en.wikipedia.org 13.05.2021)
