NOTICE:
DW12-300/100X Single Hydraulic Prop consists of hinged top cover, live cylinder, sealing dome, piston, three-way valve, handle body, oil pipe body, base body, cylinder and return spring.
DW12-300/100X Single Hydraulic Prop has the following features:
1. The outer dimensions of the stud and the live post are welded, the appearance is more beautiful, the coaxiality is ensured, and the weld is smoothly transitioned, and the weld is not affected by the handle;
2, the base is outsourced, while increasing the stroke, it also increases the force area of the base, and effectively protects the bottom of the cylinder to enhance the rigidity of the cylinder.
3. The sealing structure is designed and installed to the bottom of the living cylinder body, the piston is removed, the piston and the living column are integrated, the leakage point of the piston living column connection is eliminated, and the limit length is increased;
4. The hinged top cover and the column head are connected by wire trough, and the three-way valve is protected by the top cover under the top cover; the single hydraulic prop is a new environmental protection type support equipment, which can be used together with the metal hinged top beam. For high-grade general mining and guns, the working face support roof and the fully mechanized mining face support end can also be used for column or other temporary support.
