Hengli is providing both hydraulic solutions and a whole set of hydraulic products for main domestic and international tunnel boring machine and mining roadheader manufacturers.
Boom-type roadheader consists of a travelling mechanism, a working mechanism, a loading & transportation mechanism and a transfer mechanism. As the travelling mechanism moves forward, the cutter of the working mechanism continually breaks the rock and transports the broken rock away. As the coal industry gradually develops towards high efficiency and safety, the reliability requirements for the roadheader are gradually improved, and the corresponding reliability requirements for the hydraulic components used are becoming stricter.
Hengli mainly supplies hydraulic components such as main pump, main valve and hydraulic control joysticks for the hydraulic system of the roadheader. The V30E series and V30D series high pressure heavy duty piston pumps of Hawe InLine, a company Hengli acquired in year 2015, have more than 20 years of successful application experience for the roadheader industry. With features of long service life and high anti-contamination ability, the combination of Hawe InLine piston pump and HVSP15 series load sensing multi-way control valve can perfectly serve the hydraulic system of the roadheader. HVSP15 load-sensing multi-way valve adopts cast iron valve body with smooth flow path, simple structure and convenient maintenance. It has higher anti-contamination ability and higher reliability than machined valve body; and explosion-proof valve cover of HVSP15 multi-way control valve can fully meet the coal mining explosion-proof requirements. In addition, Hengli also provides hydraulic pilot joysticks for multi-way valves with three-point positioning and friction positioning structure to make the operation more convenient and reliable.
