On July 6, the Longgong L856TGH hybrid 5-ton loader equipped with Yuchai's flywheel range extender system successfully completed all tests and verification procedures and was officially delivered, injecting new momentum into the new energy sector of local construction machinery.
Fitted with Yuchai's YCF36+75kW flywheel range extender system, this model adopts the technical solution of "small-capacity battery + high-efficiency range-extended power generation". Eliminating the traditional configuration of high-power diesel engines and large-capacity power batteries, it retains the core advantages of electric equipment including zero emissions and low operating noise. Furthermore, it thoroughly resolves the inherent drawbacks of pure electric construction machinery such as insufficient cruising range and operational downtime for charging, enabling round-the-clock uninterrupted and stable operation. It is widely applicable to high-intensity heavy-duty working scenarios including sand and gravel yards, coal mines, steel mills and ports.
Yuchai's flywheel range-extended hybrid technology provides targeted solutions to the core industry bottlenecks restricting the electrification transformation of construction machinery - the high procurement cost and limited cruising capability of pure electric equipment, as well as the high fuel consumption and high emission levels of traditional diesel-powered models.
Featuring constant high-efficiency power generation by the range extender, direct drive operation via electric motor, and intelligent recovery of braking potential energy by the small-capacity battery, this system achieves a fuel saving rate of over 30% under heavy-duty operating conditions. It offers a high-quality solution for construction machinery to achieve low-carbon operation, cost reduction and high-efficiency sustainable operation.
