Mono Hydraulic Pillar:
Simply called Hydraulic Prop, it is different from hydraulic support, which has no pushing device, integral base and roof beam.
The structure of single column is more complicated, but it is suitable for horizontal or gently inclined coal seams with inclination angle less than 25°.
When using single column in the working face where the bottom plate is too soft, the geological conditions are complicated or the layers are divided, corresponding measures should be taken.
The Single Hydraulic Prop is not allowed to be used in the working face with excessive drenching, the working face with other performance pillars, the working face with wooden roof beams, the working face with serious acidic and alkaline drenching, as well as the working face temporarily not suitable for artillery mining and other conditions.
Hydraulic Bracket:
It consists of several hydraulic cylinders and bracket structures, and is suitable for supporting large areas and heavy loads.
The structure and performance of Single Hydraulic Prop have been continuously improved and upgraded, and gradually developed in the direction of strong, reliable, fast and automatic control.
