The present invention relates to an auxiliary cutter mounted either on the leading or trailing side of the mechanical belt drive surface miners, for flushing the kerb formed under the belt drive side. The auxiliary cutter acts synchronously with the main cutter of the surface miners, to flush the kerb thus providing...

The present invention provides an start up aid for the surface mining equipment in the form of an auxiliary drive mounted at any point of the drive line, to provide assistance to the main prime mover in case of starting high inertial loads. The auxiliary drive of the present invention also improves the engine life b...

The present invention provides a geometric synchronous belt tensioning arrangement for a multi-stage belt drive system. The invention uses a geometrical concept to synchronize the belt tensioning arrangement mechanically by varying the geometric proportions and also simultaneously reduce the total number of componen...
