2015DWL single hydraulic prop latest price

The single hydraulic prop is a new environmentally friendly support equipment. It has the advantages of small size, high support height, reliable support, convenient use and maintenance, and low overall cost. It can be used with metal hinged roof beams for high-end general mining and blasting working face support roofs and fully mechanized mining working face support ends. It can also be used as a separate point column or other temporary support. It can be applied to inclined coal seam mining working faces where the coal seam inclination angle is less than degrees. The coal seam roof and floor conditions that the single hydraulic prop is adapted to are: The backwardness of the roof does not affect the recovery of the prop. The bottom plate should not be too soft. The depth of the prop pressing into the bottom plate does not deteriorate the integrity of the bottom plate. Otherwise, the base should be enlarged. When used in blasting mining working surfaces where coal is relatively soft, protective measures should be taken on the coating surface of the living cylinder to prevent collapse. When the pillars are matched with wooden roof beams or used as point columns, the top caps should be replaced with column caps to avoid damaging the wooden beams. The
type single hydraulic prop metal prop is a metal prop with slightly increased friction resistance, which is used to support the roof of the coal mining face. Metal pillars have the characteristics of high initial working resistance and large shrinkage. After the pillars are installed, the initial working resistance can be reached quickly and the support function of the roof can be exerted as early as possible. Metal pillars can also be used on working surfaces where the roof sinks a lot and is subject to periodic pressure.
