Recently, the Quanzhou Municipal Science and Technology Plan project "JGM915 Crawler Hydraulic Excavator," undertaken by Fujian Jingong Machinery Co., Ltd., successfully passed the review by the Quanzhou Science and Technology Bureau. The project's comprehensive technology has reached the domestic leading level.

　　The "JGM915 Crawler Hydraulic Excavator" project adopts a multi-way valve with a confluence function, improving the overall working efficiency of the machine; an electronic control system has been developed, featuring multiple power settings. By collecting signals of engine speed and hydraulic system pressure and flow, it adjusts and controls the engine's output power, reducing fuel consumption with good energy-saving effects; the developed multi-function instrument panel is easy to adjust and offers a good human-machine interface; it adopts the company's proprietary patented technology "Return Oil Cooling Mechanism of Loader Dual-Pump Confluence Hydraulic System," improving the excavator's working reliability in high-temperature environments. The project products have been well received by users, delivering good economic and social benefits and broad market prospects.
