Mining dump trucks with Allison ORS transmission
Heishan Fleet (Xinjiang Tiantuo Jiye Mechanic Engineering Co., Ltd.), a mining and infrastructure company based in Xinjiang, northwest China, has placed an order for over 100 units of Tonly wide body mining dump (WBMD) trucks equipped with Allison 4800 Off Road Series (ORS) transmissions. This award, worth in excess of $50 million of annual revenue, represents a milestone in Allison’s pursuit to capture market share in the global wide body mining dump truck market.
“Since we began operating WBMD trucks equipped with Allison transmissions over six months ago, there has been a significant increase in productivity on our job sites,” said Jin Hongxin, Vice General Manager of Heishan Fleet. “Our fleet of WBMD trucks mainly operate in open coal-mining pits, separating coal from rocks, which is a harsh environment requiring long shifts from our trucks. The Allison-equipped vehicles can carry more loads per day due to powerful performance, faster acceleration and ease of operation. The new WMBD trucks have an estimated 10% increase in productivity compared to trucks with manual transmissions.
“In addition, the new trucks have significantly reduced our maintenance costs,” Jin continued. “Aside from periodic oil and filter changes, repairs are not often needed, which also reduces vehicle downtime and further enhances productivity. When the 4800 ORS transmissions do need maintenance, Allison’s leading service network provides a fast response. We look forward to continuing our partnership with Allison Transmission.”
Purchased from Shaanxi Tonly Heavy Industries Co., Ltd., a company in China’s mining dump truck industry, the Tonly 96-ton mining truck is powered by a 390kW Weichai engine rated at 2,300Nm torque and Allison’s 4800 ORS equipped with an engine-driven Power Take-Off (PTO) and a hydraulic retarder for enhanced braking, enabling optimised driving performance for off-road heavy duty-cycle operations. The Allison 4800 ORS offers several benefits to Heishan Fleet operators including increased productivity, enhanced driver control and lower total cost of ownership.
Designed to increase efficiency and reliability for medium- and heavy-duty vehicles in a wide variety of applications, Allison fully automatic transmissions are known for their patented Continuous Power Technology, featuring a hydraulic torque converter which smoothly multiplies peak engine torque, delivering more power to the wheels than other transmission technology.
Allison’s 4800 ORS transmissions are specifically designed for the severe duty-cycles trucks face in mining environments. Rigid, wide-body and articulated dump trucks outfitted with Allison Automatics accelerate quickly and smoothly on all kinds of terrain including gravel roads, loose soil, mud or steep grades.
“Allison has made my job much easier. The heavy-loaded truck is more powerful when going up hills, reducing rollback,” said Zhang Wenlong, an experienced driver who drove a manual WBMD truck for five years and has driven an Allison Automatic-equipped truck for six months. “I can concentrate on driving the truck without having to worry about selecting the correct gear or being distracted in dangerous situations. Now I make more rounds carrying coal and ore without feeling exhausted at the end of the shift.”
