Contact Us Product Center1.Easy to use.
The three-purpose valve of the suspension single hydraulic prop is set on the handle body. When the liquid is injected, the three-purpose valve does not rise with the rise of the living column, and the operation is convenient, safe and reliable.
2.High intensity.
All the sealing points of the floating single hydraulic prop are peripherals, which can be visually inspected with the naked eye. Once the pillars are leaked, the pillars can be injected or replaced at any time to ensure the safety and reliability of the roof support of the coal mining face.
3.Large work stroke.
Suspension single hydraulic props have a large working stroke, which expands the scope of use, and can also reduce the specifications of the pillars, especially the large working surface where the roof sinks.
