LiuGong Mining Trucks with rugged Allison Transmissions head to Colombia
Allison Transmission, a leading designer and manufacturer of conventional and electrified vehicle propulsion solutions and the largest global manufacturer of medium- and heavy-duty fully automatic transmissions for commercial and defense vehicles, has announced that its long-term partner LiuGong (Changzhou) Mining Machinery Co., Ltd., a subsidiary of global construction machinery enterprise Guangxi LiuGong Heavy Machinery Co., Ltd, has shipped wide body mining dump (WBMD) trucks equipped with Allison 4800 Off Road Series™ (ORS) fully automatic transmissions to Colombia.
This award represents another milestone in Allison’s pursuit to capture market share in the global wide body mining dump truck market. In China, this initiative includes both domestic and export opportunities, supporting more than $50 million annually in incremental revenue potential for Allison’s Outside North America On-Highway end market.
“We have been working with Allison Transmission for more than a decade to integrate their transmissions into several of our vehicle segments,” said Zhou Changqi, the head of R&D Center of LiuGong. “Our wide body mining dump trucks equipped with Allison fully automatic transmissions are well received at home and abroad as they can face severe duty-cycles and any harsh environment without compromising productivity and efficiency. Allison’s deep understanding of the global market, and their ability to manufacture transmissions that provide unrivalled performance, quality, durability and reliability support our company’s development strategies,” said Zhou.
“In addition, Allison automatics are easy to operate, which significantly reduces stress for the drivers. The Allison 4800 ORS requires only periodic fluid and filter changes to maintain peak performance, resulting in more vehicle uptime and lower maintenance costs.”
As the largest coal producer in South America, Colombia’s rich coal deposits require extremely powerful and reliable heavy-duty trucks. Not only do the country’s mining trucks have to haul massive loads, they also have to withstand heavy start-stop duty-cycles and day-after-day use without breaking down.
With two shifts a day, the total operation time will be around 20 hours per day.
Designed to carry a max payload of 60 tonnes with body capacity rated at 32 cubic meters, the new mining truck is powered by a 382kW Yuchai diesel engine and an Allison 4800 ORS fully automatic transmission with an output rated at 2400 Nm torque.
Equipped with an engine-driven Power Take-Off™ (PTO) and a hydraulic retarder for enhanced braking, the Allison 4800 ORS transmission ensures optimum drivability for off-road heavy duty-cycle operations. The 4800 ORS is equipped with Allison’s 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.
While a manual or automated manual transmission (AMT) loses power with every shift, an Allison smoothly shifts between gears without power interruption. This results in faster acceleration, increased performance and greater operational flexibility.
