The drive systems will support the company's 360 short ton (327t) mining truck contract with Yancoal in Australia. They will help Yancoal's mining fleet achieve increased productivity and speed on grade performance, as well as help to reduce fuel costs and equipment wear.

Bappa Banerjee, general manager of mining equipment at Wabtec, said: "We are proud to partner with NHL and support their growth. These integrated electric drive systems will improve the performance of their mining trucks by reducing fuel costs and increasing reliability, giving their customers a distinct sustainable cost advantage over the service lifetime of their trucks."

Wu Qingfeng, general manager of NHL, commented: "By combining NHL's strong manufacturing capabilities with Wabtec's domain expertise in electric drive systems, we are well positioned to improve capacity and efficiency for our customers." 

Wabtec's integrated electric drive systems enable 1.4Mlb (635t) mining trucks to carry a payload of up to 400 short tons (363t), the equivalent of 27 North American school buses. The systems can help the trucks to achieve increased productivity and speed on grade performance and help to reduce fuel costs and equipment wear.

"Wabtec continues to work with our mining customers to improved performance, reliability and lower costs, which is critical to efficient and profitable operations throughout business cycles," said Banerjee. "Our electric drive systems help mines get mineral and energy resources out to the market safer, quicker and cheaper, in a sustainable way."

The drive systems will be delivered over the next three years with an initial three units shipping to Australia in 2020.
