Rockbreaker Systems
Above-ground Gyratory
Vertical Breaker Coverage means that, within the envelope represented by hatched lines, the breaker has superior manoeuvrability for breaking rocks and turning them to break them. This situation requires a boom large enough to cover the gyratory crusher and maintain a pedestal location outside the rock box.
Maximum Reach of the rockbreaker is represented with a line showing where the tip of the tool is capable of reaching from the pedestal.
Stationary Jaw Crusher

Typically the Vertical Breaker Coverage should extend at least half way into the jaw. The rockbreaker should be mounted in line with material flow so that it can rake towards itself. Area “A” is of greatest concern, combined with the ability to rake on the grizzly “B” as far as possible. Area “C” is critical as it is desirable not to have the coverage too low, allowing extra clearance above the rock if required to break in this area.
Underground Grizzly
Coverage in this application enables raking and breaking of oversize in line with material flow on the flat section of the grizzly. Finer material is eliminated on the inclined section of the grizzly. The Vertical Breaker Coverage remains high enough above oversize on the grizzly to allow sufficient clearance for turning and breaking. In this situation, a sidemounted breaker permits working under low back heights by allowing
lower elevation of the pedestal.
Mobile Crushers
The total weight of the unit, transport height, and in some cases ease of disassembly are key factors in selecting the appropriate boom/breaker combination for mobile/portable applications. Raking the material is less important in this situation, allowing the boom to be located off to the side, thereby allowing the vertical members of the feeder to be the sub-structure for the pedestal.
