The cooling system for the model DX800LC-7 offers larger cooling capacity with lowered ventilator speed and necessary performance for the cooling ventilator. A reversible cooling ventilator is installed by default. It can be used in the opposite direction to blow out dust from the radiator, which saves time and effort on maintenance and ensures that the DX800LC-7 model is the ideal choice in difficult applications.

The DX800LC-7 model, apart from bringing excellent performance in its class, has also been designed for maximum operability on the workplace thanks to time-proven, first-rate and durable components such as the Bosch Rexroth MCV system and the system of the main pump, the rotating Doosan Mottrol device, and a very robust Berco chassis.

The DX800LC-7 excavator by default contains also the ETP (electric pump for fuel transmission). Thanks to ETP the operator can easily press a button and start refilling the fuel in the machine. It saves time and effort on maintenance.
