PRODUCT ADVANTAGESEach specification can replace 2-4 specifications of traditional piston type single props, which reduces the frequency of different types of unit pillars due to the change of working face height and the change of the moving amount of the roadway and the floor. And additional spare quantities for the pillars.
The pillars have no bearing welds, and the pillars adopt the suspension technology principle. The suspension force generated by the high pressure liquid directly acts on the top cover end, reaching four-fifths of the working resistance, and the column is only one-fifth of the force, which greatly improves the pillars. Support stability and eccentricity.
SINGLE HYDRAULIC PROP
Seal compensation and sealing tension technologyDue to the structural improvement, the imaginary top and the topping of the pillar caused by the internal leakage are avoided. Once the pillar is leaked, it can be directly inspected by the naked eye at the underground site, and the pillar can be replaced at any time; the principle of sealing compensation and sealing tensioning technology is adopted. The greater the pressure on the top plate, the tighter the sealing surface fits, and the less likely it is to leak.

PRODUCT PARAMETERS
The overall structure is simple, the service life is long; the operation is convenient, the maintenance is easy, and the pillar uplifting and maintenance rate can be greatly reduced.
