Introduction of DW31.5-200/100X Suspension Hydraulic Single Prop

DW31.5-200/100X Suspension Hydraulic Single Prop is an externally-resisting constant-resistance temporary pillar. It is mainly used for temporary support of coal mine excavation end, and can also be used for occasions where temporary support is needed in other mines and geotechnical projects. The product is made of lightweight composite materials. It can work with coal mine static pressure water, and has the characteristics of light weight, corrosion resistance and easy operation.

DW31.5-200/100X Suspension Hydraulic Single Prop is a temporary support equipment. It is a new type of equipment for coal mine industry to carry out roadway excavation and roadway maintenance for advanced support and temporary support. The product uses emulsion or static pressure water as the working medium. Because the key components (live column, cylinder, base, return spring, etc.) adopt the leading anti-corrosion technology, it has certain acid and alkali resistance and is suitable for different work. The environment is suitable for the temporary support FRP with working resistance ≤30kN as brittle material. When using, avoid impact and use three-purpose valve.
