Single Hydraulic Prop, Light Single Hydraulic Prop, DWB Light Single Hydraulic Prop
Profile
DWB light 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 corrosion-resistant and easy to operate and so on.
Application scope
DWB light single hydraulic prop for the temporary support equipment, is the coal industry for roadway excavation, roadway maintenance for advanced support and temporary support of the new equipment. The product 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 should be used to avoid the impact, supporting the use of three valves.
