Hydraulic prop, hydraulic prop suspension price, manufacturer of hydraulic prop, 2.5 m hydraulic prop glass and steel, hinged roof beams, suspended emulsion pump hydraulic prop is to have four national patents, 4 state-level science and technology awards, as well as 15 national patent offices authorized technology of high-tech products, and general hydraulic prop has the following advantages: implementing international law to strengthen the coal mine production safety roof support security management, combined with Guizhou, Yunnan, content material Chongqing, Sichuan, Liaoning and other provinces mine location of water, sulfur, fluorine, acids and other relatively high actual situation, developed a new type of corrosion-resistant hydraulic prop, namely suspension hydraulic prop [text] Product Overview suspension Prop is an outer single hydraulic prop, but the ratio of outer single hydraulic prop there is a significant advantage, and that is DWX plunger-type hydraulic prop suspension technique using the principle of suspension four-fifths of the work force reaches the resistance, the force is only one fifth column, DWX-type pillar with three valves located on the handle body, when liquid injection, three valves do not live with pillar column temperature increased easy to operate, safe and reliable. Product Features 1. With strong anti-bias load capacity and greater stability. 2. light weight, high reliability 3. 4. 5. Working stroke greatly ease of use intensity 6. 7. 8. repair and maintenance costs low with a neutral aquatic structure suspended from a hydraulic prop, cover 2, sealing cover assembly 3, plunger 4, the handle body 5, cylinder 6, the return spring 7, the base S, with three valves 8,14, O-rings 9, 13, 15, the stopper 10, the elastic cylindrical pin 11 , dust ring 12, Y-shaped ring 16, the connecting wire 17, 18, guide rings and other component parts.
