Proven reliability, durability, ease of maintenance, low operating costs and a range of safety features make our mechanical drive rigid dump trucks the trucks of choice for mining and quarrying applications across Brazil. With the highest horsepower and engine retardation in their class, they offer outstanding fuel efficiency. Advanced transmission systems, including Komatsu traction and automatic retard speed control, effectively govern downhill travel speeds on even the steepest of inclines under the weight of a full payload.
