DWX-type hydraulic prop 
 DZ-type conventional piston new piston hanging pillar DW DW new pillar of the new pillar Features: 
 A stability factor of 2-2.5 pressure cylinder 5 is more than safe, reliable DWX-type hydraulic prop 
 2 leaking fluid leakage within the fuel tank between the columns and live, is not easy to detect in the internal pillars. Leak in the living column, but saw no direct internal leakage. Column down to avoid the phenomenon, no need to pressure test a full-time member of mine can be detected directly within the eye. Saving time, effort, safe and reliable. DWX-type hydraulic prop 
 3 Type trip DZ28 minimum height of 2000 mm DWX28 pillar pillar-type minimum height over 600 mm lines of code 200 mm. Large variety of alternative specifications trip meters, stroke 800 mm. DWX-type hydraulic prop 
 Column 4 column strength for the three live connection (welded) structure. Column length as one live without welding. No welds, high strength, easy to break. DWX-type hydraulic prop 
 5 with the valve operating performance of three columns with the increase of living increase, with the live column decreases. Three in hand with the valve body, when the three workers and the valve does not move up or down to avoid the use of live-time workers climb higher column operation, safe and reliable. 
 6 corrosion resistance of the liquid working media need to float the surface of the fuel tank as long as there is slight corrosion will result in seal failure, the need to immediately overhaul 
 Working medium can be used underground water, the surface once the fuel tank corrosion, as long as the meet location requirements, the main pillars of the same performance parts for French homes Stanishev processing, corrosion, wear, corrosion, Artillery collapse. DWX-type hydraulic prop 
 7 does not seal swelling due to structural reasons and the ability to compensate. With swelling and the ability to compensate. Seal is more reliable and reasonable 
 8 does not require repair once a year overhaul overhaul overhaul to reduce costs, users do not need to invest in building pillar repair shop. 
 9 rated working pressure DZ-25-type 250KN DW-25-type 300KN pressure in the column of 80% of live 
 On the stability, bearing capacity.
