　　Characteristics of Double Telescopic Suspension Monomer Hydraulic Support Products

　　1. Adopting the principle of mining (suspension) technology, the suspension force of the pillar reaches four fifths of the working resistance, while the force on the pillar is only one-fifth. As a result, the stability and safety of the pillar have been greatly improved, and the support height, load-bearing capacity, and anti eccentric load capacity of the pillar have been enhanced.

　　2. The mining (suspended) single hydraulic prop eliminates the need for elongated cylinder, column head, and piston, with no arc welds or internal leaks. It can be visually inspected with the naked eye. Once the prop leaks, it can be replaced at any time, making it safer and avoiding the virtual top and tedious inspection work caused by internal leaks.

　　3. The three-way valve for mining (suspended) single hydraulic prop is designed on the handle body. When injecting liquid, the three-way valve does not rise with the active prop, increasing the working stroke of the prop. One specification can replace 2-4 specifications of DZ type prop, which is convenient for on-site management and use underground and reduces the labor intensity of miners.

　　4. The sealing points of the mining (suspended) single hydraulic support adopt sealing compensation and tensioning technology, and the replacement of sealing components is very convenient. The assembly, disassembly, and maintenance are simple, and only damaged parts need to be replaced.

　　5. The mining (suspended) single hydraulic prop adopts nickel phosphorus boron chemical plating surface treatment technology, which has strong corrosion resistance and wear resistance, and can use underground neutral water as the working medium.

　　6. The heat treatment process used for the active column improves the product's resistance to explosion, mechanical damage, and bending, reduces the amount of maintenance required for the column, and enhances the safety of the product.
