Product Introduction
Hydraulic support is a kind of structure used to control the surface
pressure of the coal extraction, which is developed on the basis of long wall
working face hydraulic support. They are same in the function of the control,
maintaining direct, move over and conveyor. But in caving organizations force,
assured a bracket, bracket, dust and other features are different.
Selection Requirements
（1）Hydraulic support have caving body with
hydraulic control. Request the caving body with good control performance,
opening and closing fast, reliable, big coal, less prone to jam, and has a good
spray dust suppression devices.
（2）Caving body is with a performance of
Powerful, reliable broken coal. Generally, blasting down coal and coarse coal
on a support.
（3）Support should have the function
features of pushing forward the back of the belt conveyor coal and clean up the
rear.
Main Characteristics
Support stability, continuous, favorbale effect, cost-effective. Suitable
for medium hard coal, jointed and fractured clear or good thick coal seams
