1) The proper breakdown strength

In order to effectively breaking, Hydraulic Breaker apply appropriate breakdown strength. If the breakdown force is insufficient, then the energy will not be hammering the piston effective gravel. Such a reaction force will be transmitted to the hammer body, excavator / loader arm until, causing damage to these parts.

On the other hand, excavator / loader lift arm case, if the breakdown of excessive force and crushing operations, the machine may be in the gravel instant lurch, violent hammer, hammer stones can cause severe impact crusher hammer damaged in combat operations carried out under this condition, the vibration will be transmitted crawler excavators, wheel should be avoided in this case the job.

So during combat operations, we should always pay attention to the breakdown hammer force, breakdown strength discomfort was not operating.

2) Breakdown Direction

Drill rod breakdown direction should be a straight line. Crushed rock drill rod, should amount to maintain the vertical direction operation, if hammering direction of tilt, then hammering operation, drill rod may slip, causing breakage or drill rod and piston stuck. Therefore, crushing operations, should breakdown point selected, so that the drill rod hammer hammering operation can guarantee stability.
