DWX series single hydraulic props adopt the principle of seal compensation and sealing expansion technology.
DWX type single hydraulic props have a wide range of applications and a large working stroke, It also has many advantages such as light weight and easy operation.
DW31.5-200/100X Suspension Hydraulic Single Prop is an externally-resisting constant-resistance temporary pillar. It is mainly used for temporary support of coal mine excavation end, and can also be u
1.Has a strong anti-offset capacity and greater stability. 2.High reliability and light weight.
Using the principle of plunger suspension technology, the suspension force reaches four-fifths of the working resistance, and the body is only one-fifth. The stability and safety of the single pillars
1.The operator must be trained to follow the procedures. 2.After the pillars are installed, the main circuit should be cleaned by liquid before the liquid is passed to ensure that there is no debris i
