Type single hydraulic prop. Meter single hydraulic prop. Meter suspended single hydraulic prop. Instructions for use of suspended single hydraulic prop. Suspended single hydraulic prop
The suspended single hydraulic prop is an external injection single hydraulic prop. One type, but it has a very significant advantage over the external injection single-body hydraulic prop, that is, the single-body hydraulic prop adopts the technical principle of plunger suspension. The suspension force reaches four-fifths of the working resistance, and the column stress is only The one-fifth-type pillar three-purpose valve is located on the handle body. When injecting liquid, the three-purpose valve does not rise with the rise of the living column of the pillar. It is easy to operate, safe and reliable. The
type single hydraulic prop has overcome a series of safety hazards existing in traditional props. It is a typical upgraded product and has won 3 national patents for invention and utility model. This invention was listed in the 15th Five-Year Plan by the Ministry of Science and Technology. National key promotion project of scientific and technological achievements.
This mining single hydraulic prop is matched with the metal hinged roof beam and is used for the ends of general mechanized blast mining working faces and fully mechanized mining working faces in coal mines or for temporary roof support. It is suitable for working faces with a coal seam inclination angle smaller than When taking measures, it can also be used on inclined mining working faces. This series of single hydraulic props has good stability and outstanding technical performance advantages. It increases the single support height of high-grade general mining working faces in coal mines from 3.0 meters to 3.0 meters. Coal seams below 3.0 meters can be mined to the full height at one time. At the same time, it can provide end and advance support for working faces with coal seam thickness below .m.
