With the continuous and reliable operation of the Pangxiang PX40 ATCA2 automatic mining dump truck equipped with the Allison 4500 ORS automatic transmission in the lime mine in Saraburi, Thailand, the Allison automatic transmission is considered as its The best configuration in the truck powertrain. These automatic dumper dump trucks have the advantages of uninterrupted power, smooth braking, convenient operation, and reduced maintenance, which have improved the operational efficiency of the fleet and have been highly recognized by Thai users and vehicle manufacturers.
Allison Transmission
Saraburi is an important cement production center in Thailand with numerous mines and cement plants. Phatub needs a mining dump truck capable of transporting 40 tons of limestone to transport the ore through a rugged, steep road to the Yamashita gravel yard. This requires the mine car must have a strong horsepower, continuous climbing ability and precise handling.
Therefore, after Pengxiang and Thai technicians jointly analyzed the operating conditions in the mining area, the vehicle was equipped with an Allison 4500 ORS fully automatic six-speed transmission and a 420-hp FAW Xichai engine with a maximum output torque of 1,900 Nm. This specially designed powertrain enables the vehicle to produce 244,500 Newtons of maximum traction on a 41.4% steep slope, which fully satisfies the power requirements for heavy-duty transportation of mine vehicles and improves the efficiency and productivity of mining trucks.
Li Hailiang, director of the mining car factory of Pengxiang Automobile Co., Ltd., said: “Allison Continuous Power TechnologyTM provides uninterrupted power to the vehicle during shifting and acceleration. At the same time, Allison automatic transmission integrated hydraulic retarder provides smooth braking for the vehicle and avoids brake failure.
In addition to safety advantages, effective damping in the transmission process reduces the failure rate of the drive system. Chaveng Sakarin, Drive Systems Manager of Anglo-Thai Ltd. added: "The application of the retarder reduces the heat transfer from the brake drum to the wheels and prolongs the service life of the tires and the drive system. Therefore, the breakdown time and maintenance cost of the automatic car Less than manual vehicles."
Since 2012, Pengxiang and other Chinese mining dump truck manufacturers have entered the Thai market, and excellent after-sales service is one of the keys to success. Relying on Allison's powerful global seamless service network, Anglis-Thai Co., Ltd., an agent of Allison Transmission in Thailand, provides timely and reliable after-sales service and technical support to help Pengxiang Thailand Service Station better serve its customers.
Li Hailiang is very satisfied with this: "Allison Transmission Co., Ltd. is the world's largest manufacturer of automatic transmissions for heavy-duty commercial vehicles. It has advanced technology, reliable quality, and convenient after-sales maintenance. This is why we have always favored Allison."
