The room housing the electric controls on the bucket wheel is fitted with air-conditioning. The machine has four large electric motors that drive the hydraulic pumps at 335 KW. The hydraulic solenoid valves are controlled by a 24-volt system. The conveyor belts for the loading belt and unloading belt are electrically driven. All other components are hydraulic. The cable drum with approx. 450m cable is located at the back of the machine between the two crawlers. The cable drum works automatically when the machine moves. |
