Kipper
A tipper truck, known also as a dumping truck, dump trailer, dump lorry or dumper lorry or a dumper for short, is used for transporting materials.
A typical tipper 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.
