MWC7.8/0.32L Mining Hydraulic Excavator (Diesel)

MWC7.8/0.32L is a flameproof diesel-powered mining hydraulic excavator manufactured by Jiangsu Tianmei Electromechanical Technology Co., Ltd., a national high-tech enterprise based in Xuzhou, Jiangsu, China. It is powered by a flameproof diesel engine with 80 kW rated power for strong, reliable operation, and exhaust emissions meet China Stage III standards. It is widely used for roadway floor dinting, ditch cutting, floating coal cleaning, floor leveling, rock breaking and loading, and auxiliary excavation in level and inclined roadways. Its compact lightweight, low-center-of-gravity structure and small swing radius suit narrow underground spaces. A load-sensing hydraulic system with pilot control delivers smooth, shock-free operation, while the three-section boom with a 90-degree rotating middle arm, combined with 360-degree machine rotation, enables full-space excavation and breaking without obstacles. A front dozer blade levels roadways and stabilizes the machine during reverse-slope operation. Quick-change attachments including bucket, breaker, hydraulic shear and milling head make the machine multi-functional, and wireless remote control allows operator-free operation for safer underground work. Key specifications include operating weight 7800 kg, bucket capacity 0.32 m3, maximum digging force 50 kN, digging radius 5100 mm, digging depth 2350 mm, digging height 5180 mm, dumping height 2450 mm, minimum swing radius 1600 mm, travel speed 0-58 m/min and ground clearance 225 mm.
