2020-07-20

In order to effectively crush, the destructive power of the excavator's hammer is very strong. But how much effort should be used for construction? This problem plagues many people. After all, the breakdown force is insufficient to effectively crush the stone; and if the breakdown force is too large, the reaction force of the hammer force will be transmitted to the breaker body and the boom of the excavator, resulting in parts Damage. The hammer head is often weak during use. What should we do if this phenomenon occurs? What should we do in daily use?

1. After discovering that the hammer head of the excavator is weak, check whether the nitrogen pressure is abnormal;

2. Check if the static oil pressure is sufficient;

3. Check whether the working oil is sufficient;

4. The size of the steel and whether the screws of the guard plate are loose;

5. Check the bushing clearance and wear;

6. Check whether the hydraulic oil is sufficient;

7. Is the stop valve fully opened;

8. Loosen the lock nut of the overflow valve.

As an important working tool of hydraulic excavator, breaking hammer should pay attention to the following points in actual work.

1. The basic safety equipment must be up to the standard, and a debris shield is installed in front of the cab to prevent the flying debris from causing personal injury during work;

2. The breaker can only be used when both the excavator and the hammer head are normal;

3. During construction, all on-site personnel including the excavator driver must wear earplugs and masks;

4. Drivers should not operate the equipment when they are drunk or have adverse reactions after taking drugs;

5. Once it is found that someone has accidentally entered the construction dangerous area, immediately stop the operation until the other person leaves;

6. When working, strictly abide by the safety operation regulations.

The above is the inspection method after the excavator hammer head is weak and the precautions for daily use of the equipment, I hope it can be helpful to you.
