Roof support Yurmash 2SH-16/32
The YURMASH 2SH-16/32 chock-shield support is designed to mechanically strengthen and control the roof including the heavy ones according to the rock pressure manifestation to ensure a safe working face area by the top caving-in method and advance the longwall conveyor as coal is worked out in the fat and steep beds. The roof support is outftted with devices to hold up and secure roof support units as well as adjust and route face conveyers. The support has a sliding shield to synchronously support the roof in the goaf environment and damp the heading.
