The wide-body mining dump trucks have developed rapidly in China in recent years. With its advantages of large load capacity, high transportation efficiency and strong profitability, it has gradually become the main equipment for mining operations.
Since 2008, China National Heavy Duty Truck Power Research Institute has designed and developed special engines for WD615, D12 and natural gas for the special conditions of mining dump trucks, which are widely welcomed by many users. In 2012, China National Heavy Duty Truck Mine Card is expected to be used for personal use. The total number of engines and engines supporting the outside of the Group exceeds 6,000 units, and the market share in the segment exceeds 50%, which has become the mainstream power for China's mining dump trucks.
The heavy-duty Mining Dump Truck exclusive engine exclusively uses a double-wall reinforced wide-body to significantly increase the rigidity and strength of the engine body. According to a large amount of practice for a long time, the specific power of the CNHTC Mining Dump Truck is fully adapted to the rough and uneven road conditions, the large number of corners, and the vibration of the vehicle, which effectively overcomes the tendency of the narrow-body engine's prone to tearing the timing gear chamber. Batch failure.
For the long-distance uphill or downhill running conditions of the mining dump trucks, the EVB is standard on the CNHTC Mining Dump Truck engines, which significantly increases the braking performance of the vehicle and reduces the driver's work intensity while reducing The wear of the entire vehicle brake system also improves the safety of the vehicle's operation.
In view of the features of the mine dump truck engine operating at around 2000 rpm for a long time, CNHTC optimizes the matching between the air intake system and the fuel supply system so that the engine can reduce the high-speed operating conditions while ensuring the starting performance. Fuel consumption.
In order to ensure the effective supply of engine oil when working on steep slopes, the CNHTC dump truck engine is equipped with a dual-stage oil pump as standard to ensure effective lubrication of the engine and reduce wear. In addition, the application of automatic tensioner and multi-ribbed belt drive can increase the service life of the engine belt and reduce the workload of the driver; the application of the electric preheating device ensures that the engine can start normally in cold weather; the use of internationally renowned brands MANN+HUMMEL's fuel filtration system can effectively improve the filtration efficiency, reduce the filtration resistance, and have the oil-water separation function. In response to the harsh operating conditions of mining dump trucks, the dedicated power has also strengthened and optimized key internal engine parts such as pistons, connecting rods, cylinder liners, bearing bushes, intake and exhaust valves, etc., to make the whole machine resistant to thermal shock and The mechanical impact capability has been greatly improved.
Cnhtc Engine's advantage lies not only in the product itself, and timely and satisfactory after-sales service is also a key factor in attracting users. China National Heavy Duty Truck Group Hangzhou Engine Sales Co., Ltd. is a wholly-owned subsidiary of China National Heavy Duty Truck Group responsible for engine sales and services. In areas around China's important mining areas and with large product retention areas, there are accessories center warehouses and service stations to ensure the timely and adequate supply of accessories and ensure the timely removal of faults, thus ensuring the high attendance rate of the entire vehicle.
