Using the principle of plunger suspension technology, the suspension force reaches four-fifths of the working resistance, and the body is only one-fifth. The stability and safety of the single pillars
Contact Us Product CenterUsing the principle of plunger suspension technology, the suspension force reaches four-fifths of the working resistance, and the body is only one-fifth. The stability and safety of the single pillars are greatly improved, and the support height, load bearing capacity and load resistance of the pillars are also improved. Moreover, the arc welding method is no longer used on the movable column, which avoids accidents such as the emergence of the top due to the fracture of the weld seam, and ensures the life safety of the miner.
There is no piston in the cylinder, and there is no problem of internal leakage. According to different pillar specifications, the overall weight of the suspension hydraulic prop is reduced by more than 15-13% than that of the piston hydraulic prop, even lighter than the alloy pillar, and the bearing capacity is improved. 25%, the use range has been expanded by 200%, the minimum height of the pillars is greatly shortened, and transportation is convenient.
