Mechanism for the displacement of a chopper hammer, where the hammer in question is one of those used to start coal in underground mining operations, such hammer being associated with a pusher cylinder mounted articulately on a support that is in turn mounted, with faculty of displacement in one direction and another, on a horizontal estemple of hydraulic drive for its extensibility, all having pneumatic means to produce the different drives and movements of the aforementioned element, including the control support of the hammer, essentially characterized in that the hammer pusher cylinder has external means for its attachment to a winch assembly that is actuated by a pneumatic control to produce the vertical displacement of the hammer assembly, the winch being in turn related to a set of displaceable pulleys and guided on a horizontal top beam, and n order to produce the horizontal displacement of the hammer assembly, said beam being in turn provided with suitable supports and stop elements that limit said horizontal displacement, there being pneumatic means of annual drive to drive said displacement elements.
