Shandong Jining Machinery Co., Ltd. is the same hydraulic prop manufacturers, hydraulic prop suspension parts, Inner Mongolia hydraulic prop manufacturers, hydraulic prop suspension, fiberglass hydraulic prop model price, three valves, hinged roof beams DWX suspension Note the difference between the pillar and the other pillars of the inner and outer injection advantage pillars: 1) eliminating the pillar caused due to internal leakage virtual roof, off the top, smothered wounding accidents; 2) large hydraulic work schedule, expanding the scope of use, improving the recovery rate of coal resources; 3) In the case of the pillars supporting the high-pressure, and the greater the pressure seal more tightly; 4) the use of a plunger (suspension) technical principles, higher pillar of stability and security; 5) column higher strength and reliability, to avoid seam roof collapse, etc. due to fatigue fracture caused by accidents; 6) sliding seal point compensation and sealed with a seal swelling technical principles. Improve the safety performance of the sliding seals and seal point reduction in the seal replacement rate; 7) greatly reduces the labor intensity of the miners; 8) suspension Prop working medium groundwater, avoiding mine working environment and groundwater pollution; 9) liquid column play a very good cushioning effect and improve the safety of the coal face; 10) using a special hardening treatment process, increase column strength, greatly improving safety; 11) DWX Series suspended Prop extremely low failure rates. 100 Bore Mine suspension hydraulic prop Product Specifications Model maximum height (mm) minimum height (mm) Working stroke (mm) working resistance Weight (kg) pillars of the scope of work (mm) Rated pressure (MPa) DW06-300 / 100X 630 410 220 300 21 410-630 41.4 DW08-300 / 100X 800 500 300 24 500-800 DW10-300 / 100X 1000 605 395 27.5 605-1000 DW12-300 / 100X 1200 710 490 30.5 710-1200 DW14-300 / 100X 1400 820 580 34 820-1400 DW14-300 / 100X suspension Prop manufacturers, single pillar model, DN hydraulic prop within the injection, liquid injection gun, three valves, 0.8 m hinged roof beams, DJB800 / 300 hinged top beam price DW14-300 / 100X suspension Prop manufacturers, single pillar model, DN hydraulic prop within the injection, liquid injection gun, three valves, 0.8 m hinged roof beams, DJB800 / 300 hinged roof beams price
