Jack fittings

Adjusting jack is an important part of hydraulic support. In coal mine production, especially in the working face with poor floor condition and inclined coal seam, the support will produce skew after moving, which is not conducive to support management and sliding operation. The adjusting jack is used to adjust the adjacent supports in the process of moving the support, so as to ensure the overall synchronization and stability of the support, effectively manage the support and supporting roof, facilitate smooth sliding, and ensure safe and reliable production.
