Product Description

Coal Mining DWX Series Small Suspension Hydraulic Props for Sale
Characteristic Of Coal Mining DWX Series Small Suspension Hydraulic Props 
(1)Strong anti-bias load capacity and greater stability. 
Coal Mining DWX Series Small Suspension Hydraulic Props suspension using plunger technical principle, the hydraulic suspension force plunger directly through the lumen of the role of pillars on the top cover, so that the hydraulic suspension forces share the pillars around four-fifths of the working resistance, so that the shaft plunger upward force is only one-fifth of the working resistance, improved pillar of stability and security, but also greatly increased the height of the support pillars and carrying capacity;
(2)high reliability
Coal Mining DWX Series Small Suspension Hydraulic Props in the column is no longer the arc welding process which is not easy to guarantee the technics, but also improve the strength and reliability of the column, avoiding roof collapse and other accidents caused by the weld fracture, to ensure the safety of staff.
(3) Light weight
According to Pillar different specifications, the entire column is now at home and abroad with the weight ratio pillar reduce 15-30%, but the resistance of its work, the working stroke and stability safety factor was higher than the aluminum pillars.
(4)Long working stroke
Using a wide range of working stroke with DWX large pillars, expanding the scope of use, can also reduce the pillars specifications and varieties, especially the larger roof sinking face. DWX Series Small Suspension Hydraulic Props still meet the big drop at constant increasing resistance, not only prop convenient, but also improve the pillar recovery, reducing the pillar consumption, lower production costs.
(5)Convenient to use
Both at home and abroad hydraulic prop is to install three valves in the living column stigma welding, when the plunger is raised, the operator must follow its rise, especially for higher face, the operator is very convenient nor safe; while DWX series pillar three valves located on the handle body, when the injection fluid, three valves do not live with the column temperature increased, easy to operate, safe and reliable.
