Equipment shifting devices MZD-600 UPL-LEGWAN UPN-WISENT
Equipment shifting devices MZD-600 and UPL-LEGWAN are designed to non-chain displacement of mining machines and devices using hydraulic cylinders (actuators) through ratchet mechanism and beams.
UPN-WISENT is designed to displace (move) the AFC’s auxiliary drive which is being performed through two hydraulic cylinders (actuators) mounted with supporting plate on one side and main plate (assembled with AFC auxiliary drive) on other side. UPN-WISENT and UPL-LEGWAN work as vertical stopping system.
Equipment shifting devices can be applied in underground mining methane and non-methane excavations, considered as level “a”, “b” and “c” area exposed to methane explosion hazard, as well as grade “A” and “B” of coal dust explosion hazard. Devices have been classified as Group I, category M2 due to its application in areas exposed to explosion hazard (according to directive 2014/34/UE).
