Mining excavation’s removal device URW-PANDA and URW-PANDA II
Mining excavation’s removal device URW-PANDA and URW-PANDA II is designed to automize work at underground mining excavations referring to removal (disassembly) of steel arch supports in underground roadways. The device allows to prop the steel arch support, untighten the fasteners and to safely removal (disassembly) the supports’ elements, without necessity of keeping the employees in hazard area. Disassembly of steel arch support elements is possible through supporting removal prop and side arms. Construction of the device allows its shifting through installed actuators. During device shifting, steel arches are being constantly supported through one or two propping beams, depending on stage of device’s work.
