Mining Truck Motor Services
Over the past decade or so we have become involved with the repair and retrofitting of the Siemens 1,500 KW and 1,250 KW AC drive motors used in the colossal Liebherr and Euclid-Hitachi Mining Trucks. These are the largest dump trucks ever manufactured and are used around the world in a variety of mining operations. Each truck contains a diesel generator that supplies power to a pair of electric motors (one mounted on each rear wheel). These electric drive motors (not a diesel engine) propel these trucks up and down the mines in forward and reverse at varying speeds.

Because of the substantial capital investment it takes to purchase one of these trucks, they are expected to operate around-the-clock. It goes without saying that these mines are located in some of the world's harshest environments and therefore the motors must be designed and built to withstand these conditions. Even though the best materials and most innovative designs have been utilized in these motors, eventually the environment
wins out.
 

    These motors arrive at our facility from mines throughout the world and we meticulously repair them using coils, insulation and other parts supplied to us by Siemens AG. Our training has been alongside Siemens craftsmen in Germany who have taught us the proven methods they use when repairing these motors. Siemens AG (Automation & Drives Division) has chosen dahl-beck electric to be their official authorized partner in the United States for Large Drives & Traction Motors. We are truly honored to be partnered with such a fine organization.
