Hydraulic Prop

Introduction of DWXA Mining Single Hydraulic Supporting Prop DWXA Mining Single Hydraulic Supporting Prop is improved based on DW mine single hydraulic prop product. The product with advantages of good stability, outstanding technical performance is widely used in the production of its traditional wooden pillars supporting metal friction compared with high recovery, supporting safe and reliable, working resistance constant, setting load is high, the use of flexible benefits.

Advantages of DWX Suspension Single Hydraulic Prop Acrow Jack DWX Suspension Single Hydraulic Prop Acrow Jack is a high grade mechanized mining face of the equipment, but also the longwall face end support equipment. DWX Suspension Single Hydraulic Prop Acrow Jack applies to coal mining face of the roof support, mechanized mining face of the end plate supporting the head, ahead of tunneling support. Because of its carrying capacity, anti-bias load capacity, large working

Application of DWB 28 Mining Light Single Hydraulic Acrw Prop DWB 28 Mining Light Single Hydraulic Acrw Prop is an emulsion or hydrostatic water as the working medium, as key parts (plunger, cylinder, base, return spring, etc.) with a leading anti-corrosion technology, there are certain acid and alkali resistance, suitable for different work environment for working resistance ≤ 30kN, the temporary support is brittle FRP materials which should be used to avoid the impact,

Introduction of DWB FRP Fiber Reinforced Plastics Single Hydraulic Prop DWB FRP Fiber Reinforced Plastics Single Hydraulic Prop for foreign Note constant resistive temporary pillars, it is mainly used in coal mines to dig ends temporary support, can also be used for other mining and geotechnical engineering applications require temporary shoring, the use of lightweight composite products material produced. Available coal hydrostatic water to make it work, with a light weight

Introduction of DWS25 Double Telescopic Suspension Hydraulic Acrow Prop DWS25 Double Telescopic Suspension Hydraulic Acrow Prop using mine (suspension) technical principles, pillars suspension force to achieve four-fifths of the working resistance, the column is only one fifth of the force. Thus greatly improving the pillars of stability and security, improve the supporting pillar height, carrying capacity and anti-bias load capability. Application of DWS25 Double Telescopic

Introduction of DW35 Underground Coal Mine Supporting Acrow Prop DW35 Underground Coal Mine Supporting Acrow Prop as an element of individual mining support system, are used for reinforcing double timber of headings – as support of simple wall splits, independent support in headings at risk of ground tremors, as an reinforcing element for other type of support systems in longwall roof supports. Model Specification DWDW35-150/100 D- single hydraulic prop W-out injection type

Introduction of DW Outer Injection Coal Mining Single Hydraulic Prop DW Outer Injection Coal Mining Single Hydraulic Prop increasingly widely used in the production of its traditional wooden pillars supporting metal friction compared with high recovery, supporting safe and reliable, working resistance constant, setting load is high, the use of flexible benefits. Outer single hydraulic prop can be used alone or in combination with metal hinged roof beams supporting the use,
