In the summer in Chinese mines in Xinjiang, high heat conditions of over 40°C and sandstorms are frequent which represent a major test to equipment along with high altitude; with temperatures in the winter dropping to an average of -20°C in January. Even in these conditions, Xugong-headquartered global mining equipment major XCMG says it has been successful in deploying a large fleet of XKT136 wide body extended range methanol powered mining trucks, part of the OEM’s push to use new and greener energy resources.

XCMG states: “​​​Methanol has the characteristics of a high octane rating but with very low emissions. It can reduce hydrocarbon emissions by 40% in the complete combustion state, and greatly clean carbon deposits in the engine and oil scaling in pipes. Compared with the equivalent traditional diesel fuel vehicle, the XKT136 truck can also save more than 35% in energy consumption, representing more than 400,000 yuan [US$55,000] a year.​​​​”

The XKT136 has a dual-motor extended range power generation module and dual-motor drive system allowing it to achieve around-the-clock operation. It has a maximum output power of 1,088 hp, so that the gearbox can operate efficiently without interrupting the automatic shift of power under full working conditions.

The methanol tank capacity is 1,200 L which XCMG says is the largest in the industry​ and can last for over 12 hours. At the same time, it is equipped with an efficient and intelligent energy recovery system, which can maximise the cruising range of the vehicle. XCMG says it is part of a “historic leap” in achieving green mining from standard emissions to near zero emissions and finally zero emissions.

XCMG says despite the climatic extremes, the new methanol mining trucks have achieved excellent performance since deployment in January 2023.​​ ​​​”This truck has performed very well at the operation, with over 95% availability and high transportation efficiency. If it is extended to the whole of Xinjiang, the emission reduction benefits will be obvious.” To date more than 350 units have been deployed.

The OEM adds: “Green intelligence, safety and efficiency have become the requirements of these times for the sustainable development of the mining industry. XCMG will continue to innovate with green development concepts, upgrading of technical solutions, provision of green mining equipment, and striving to make resource extraction more efficient.​”
