DWX suspension type single hydraulic prop introduction

High working resistance, light weight, long service life, large working stroke, use cost low, easy maintenance, low maintenance cost, operation, wide using range and stability is good wait for a characteristic, and can satisfy the requirements of the various working conditions.

Can be used in the coal seam working face mining height are broken 0.5 meters to 4.5 meters; Its diameter, 100, 90, 80, 90 series, according to the coal mining height are broken, roof pressure can be flexible and economical choice, taking place of DZ single hydraulic prop, micro pillar, urgent, increases the resistance of friction and wooden pillars of good products.

DWX suspension type single hydraulic prop feature

1) strong ability of partial load resistance and greater stability.

DWX pillar adopt plunger type suspension technology principle, make the hydraulic lift force directly through the role of the inner chamber pillar live column on the roof, make the hydraulic lift force split the about four 5 of the support working resistance, make live column in the stress of the shaft up only about one 5 of the working resistance, improve the stability and security of the pillar, also greatly improved the pillar support height and carrying capacity;

(2) High Reliability

DWX pillar on the pillar type no longer sets of arc weld process difficult to guarantee, also raised the pillar of strength and reliability, avoids because of weld fracture caused by roof caving accident hidden danger, ensure the safety of staff.

(3) light weight

Pillar according to the different specifications, the whole column weight than the current pillar at home and abroad to reduce 1 5-30%, but the working resistance, working stroke and stability safety factor is higher than that of aluminum alloy pillar.

(4) Long work schedule, Using a wide range

 DWX pillar type work schedule, enlarged the use scope, can also reduce the mainstay of specifications varieties, especially working face with large Numbers of roof subsidence. DWX pillar type can still meet the big drop from the constant increase of resistance, prop-pulling not only convenient, but also improved the pillar recovery, reduce the pillar consumption, reduces the production cost.

(5) convenient to use

Individual hydraulic prop are left three at home and abroad with valve head welding on the live column, when live column increases, operators must over its rise, especially for high working face, the operator is not very convenient nor safe; And DWX pillar type series of three use valve in hand on the body, when the filler, three valve can't be with live column rises, convenient operation, safe and reliable.
