DWB light single hydraulic prop

Profile

DWB light single hydraulic prop for foreign Note constantresistive temporary pillars, it is mainly used in coal mines to dig endstemporary support, can also be used for other mining and geotechnicalengineering applications require temporary shoring, the use of lightweightcomposite products material produced. Available coal hydrostatic water to makeit work, with a light weight corrosion-resistant and easy to operate and so on.

Applicationscope

DWB light single hydraulic prop for the temporarysupport equipment, is the coal industry for roadway excavation, roadwaymaintenance for advanced support and temporary support of the new equipment.The product is an emulsion or hydrostatic water as the working medium, as keyparts (plunger, cylinder, base, return spring, etc.) with a leadinganti-corrosion technology, there are certain acid and alkali resistance,suitable for different work environment for working resistance ≤ 30kN thetemporary support is brittle FRP materials should be used to avoid the impact,supporting the use of three valves.
