Mechanical revolving car dumper MRCD
Revolving dumpers with electrical drive are designed for unloading non-disengageable train cars in the shaft insets of coal mines skip hoisting or single cars in pithead buildings of cage hoisting of mining trucks (MT). Explosion-proof models are produced thus they can be exploited in the gas and dust hazardous mines.
