Hydraulic support In Mining

Product Introduction

The hydraulic support is developed on the basis of shield and chock-shield supports. It can be used in the different conditions such as medium stability roof, stability roof, broken roof, soft roof, etc. The hydraulic support is to support, both a bracket cover.

The hydraulic support including 6 structural system, they are endpoint location, coal seam, roof beam, beam cover, base and backbone.

Main Characteristics

（1）Support stability, good top beams, perfect roof performance.

（2）Structure is complicated，more steel consumption,high cost.

（3）Have a larger working space, easy for vent and pedestrians.

Product Advantages

Vertical support have a distances from the wall, that bracket support would be better. In addition, it is with high stability for average contact pressure with top and bottom.
