<p>The dumper has a dump body (80), and a heating circuit (100) for heating a base surface of the dump body and comprising a heat transfer medium such as liquid carrier medium e.g. mixture of water and glycol, and hydraulic oil. The heating circuit comprises a central heat generator and is coupled with a liquid circuit (110) that cools a drive unit (10) i.e. diesel engine. The heating circuit comprises a motor-driven circulating pump (60) to circulate the liquid carrier medium, and a shut-off element (30), which is mechanically actuated by an actuator to shut off the heating circuit.</p> |
