HL85 8 Ton Excavator Rock Breaker Jack Hydraulic Hammer

HL85 High Quality Excavator Breaker Rock Breaker Jack Hydraulic Hammer

Operation guide of hydraulic breaker:

Precautions

1. A debris shield device should be installed in front of the cab to prevent damage caused by flying debris during operation.

2. During the operation, all on-site personnel including excavator drivers must wear earplugs and masks.

3. The driver should sit on the seat to operate the breaker, and only when the excavator/loader and the breaker are in normal state can the breaker be broken.

4. If someone enters the dangerous area of ​​operation, the operation of the breaker should be stopped immediately; because compared with the excavation operation, the personnel are easily hit by the flying fragments during the operation of the breaker.

5. When operating with a breaker, the operation of the excavator/loader should comply with the safety operation regulations of the excavator/loader manufacturer. Make sure to use a well-installed and properly debugged breaker.

6. Do not operate the breaker when you are drunk or have a reaction to taking medicine.

When disengaging the curved back for maintenance and overhaul, ensure that the working conditions are stable and lower the working device.

the right way to work

1. Proper breakdown force

For effective breaking, the breaker should apply a suitable breakdown force. If the breakdown force is insufficient, the hammering energy of the piston will not be able to effectively break the stone; thus the reaction force of the hammering force will be transmitted to the breaker body, the boom of the excavator/loader, etc., thereby damaging these parts.

On the other hand, when the excavator/loader boom is lifted, if the breakdown force is too large and the crushing operation is performed, the machine may suddenly tilt at the moment of the crushed stone, and the crushing hammer is violent, and the crushing hammer violently hits the stone, which will cause crushing The hammer is damaged. In this condition, the striking operation will be carried out, and the vibration will also be transmitted to the crawler and wheels of the excavator. Operation in this condition should be avoided.

Therefore, during the striking operation, always pay attention to the breakdown force of the breaker, and do not work when the breakdown force is not appropriate.

2. Breakdown direction

The breakdown direction should be in line with the steel brazing. When the steel drill breaks the rock, it should be kept in the vertical direction. If the hammering direction is inclined, the steel drill may slip off during the hammering operation, causing the steel drill and the piston to break or get stuck. Therefore, during the crushing operation, the breakdown point should be selected, so that the hammering can be guaranteed to be stable during the hammering operation of the steel drill.
