DW10-400/110X Suspended Single Unit Hydraulic Support Manufacturer Shandong Single Unit Hydraulic Support

Description :

　　The DW10-400/110X suspended single hydraulic prop has the characteristics of high working resistance, light weight, long service life, large working stroke, low usage cost, low maintenance cost, easy operation and use, wide range of use, and good stability, and can meet the technical requirements of various working conditions.

　　DWX type pillars can be used for mining coal seam working faces with a height of 0.5 meters to 4.5 meters; It has cylinder diameters of 100, 90, 80, and 63 series, which can be flexibly and economically selected according to coal seam mining height and roof pressure. It is an excellent product to replace DZ type single hydraulic prop, micro, rapid, and increased resistance friction prop, and wooden prop.

　　Main features of DW10-400/110X suspended single hydraulic prop

　　(1) Has strong resistance to eccentric loads and significant stability.

　　The DWX type pillar adopts the principle of plunger suspension technology, which allows the hydraulic suspension force to directly act on the top cover through the inner cavity of the pillar's active column, sharing about four fifths of the pillar's working resistance with the hydraulic suspension force. This reduces the axial force on the active column to only one-fifth of the working resistance, improving the stability and safety of the pillar, and greatly increasing its support height and load-bearing capacity;

　　(2) High reliability

　　The DWX type pillar no longer has arc welds on the pillar that are difficult to guarantee by the process, which also improves the strength and reliability of the pillar, avoids potential accidents such as roof collapse caused by weld fracture, and ensures the safety of workers.

　　(3) Lightweight

　　According to the different specifications of the pillars, the weight of the entire pillar is reduced by more than 15-30% compared to the currently used pillars at home and abroad, but its working resistance, working stroke, and stability safety factor are higher than those of aluminum alloy pillars.

　　(4) The work schedule is long,

　　The DWX type pillar has a wide range of applications and a large working stroke, which expands its range of use and reduces the variety of pillar specifications, especially for working surfaces with large roof subsidence. The DWX type pillar can still meet the requirements of large constant increase resistance reduction distance, which not only facilitates the return of pillars, but also improves the recovery rate of pillars, reduces pillar consumption, and lowers production costs.

　　(5) Easy to use

　　At present, both domestic and foreign single hydraulic supports are welded with the head of the three-way valve installed on the active column. When the active column rises, the operator must follow suit, especially for higher working surfaces, which is inconvenient and unsafe for the operator; The DWX series pillar three-way valve is installed on the handle body. When injecting liquid, the three-way valve will not rise with the rise of the active column, making it easy to operate, safe and reliable. zmjt055
