1. Appropriate breakdown force 　　 　 　

In order to effectively break, the excavator hydraulic hammer should use a suitable breakdown force. If the breakdown force is insufficient, the hammering energy of the piston will not be able to effectively crush the stone; in this way, the reaction force of the hammering force will be transmitted to the excavator hydraulic hammer body, the boom of the excavator/loader, etc., thereby damaging these components. On the other hand, when the boom of the excavator/loader is lifted, if the breakdown force is too large and the crushing operation is carried out, the machine may suddenly tilt at the moment of crushing the stone. If the hammer is damaged, the vibration will also be transmitted to the crawler and wheels of the excavator under this condition. It should be avoided to work under this condition. Therefore, during the striking operation, always pay attention to the breakdown force of the excavator hydraulic hammer. The breakdown force is not suitable. Don't do homework at that time.

2. Direction of breakdown

The direction of breakdown should be in line with the steel brazing. When the steel drill breaks the rock, the work should be done in a vertical direction. If the hammering direction is inclined, the steel drill may slip off during the hammering operation, causing the steel drill and piston to break or jam. Therefore, when the crushing operation is performed, the breakdown point should be selected so that the hammering stability can be ensured during the steel drill hammering operation.
