Stedman Machine Co.’s engineered jack screw wedge design on its Grand Slam horizontal shaft impactors simplifies breaker bar maintenance and repair. Streamlined breaker bar rotation or replacement minimizes downtime and maximizes ease of use. Regular maintenance extends the life of the breaker bars for horizontal shaft impactors.

The Grand Slam impactor’s unique design allows for fast, safe rotation or removal of rotor breaker bars by a single operator. Opening the hinged front or rear housing allows unobstructed access to all areas of the crushing chamber and rotor. The maintenance crew member opens the hinged housing, removes the H-retainer and inserts the rotor lock table to secure the rotor. The breaker bars easily slide out after simply removing the jack screw wedge.
