Specification

The MB 330 MONO shearer with a 330 kW main engine power is designed to mine short residual pillars of 1.6 to 3.5 meter thickness.

Turning the arm using a hydraulic motor with a brake and coupling against overload ensures seamless operation of the shearer.

Travel of the shearer is ensured by a separate 30 kW motor. The shearer is equipped with an online and off-line diagnostic system that allows continuous recording of the operating and fault conditions of the shearer.
