What should be paid attention to when the excavator breaker is working?

1. ExcavatorHammerSuspend work in the event of severe hose vibration

Check whether the high-pressure and low-pressure hoses of the excavator breaker vibrate too violently. If this happens, there may be a fault, and you should immediately contact your local designated service office to obtain maintenance services. Further check whether there is oil leakage at the joint of the hose. If there is oil leakage, re-tighten the joint. As shown in the figure, during the work, you should visually check whether the steel drill has a margin. If there is no margin, it must be stuck in the lower body. The lower body should be removed to see if the parts should be repaired and replaced with new faulty parts.

2. Pause work (avoid excessive air strike)

Hammering should be stopped once the stone is broken. If the air strike continues, the bolt will loosen or break, and even the excavator and loader will be adversely affected. When the breaking force of the hammer is unreasonable or the steel drill is used as a pry When the rod is used, the phenomenon of empty strike will also occur. (The sound of the hammer can be changed when the hammer strikes in the air)

3. The excavator breaker hammer cannot be used to carry stones

Do not use steel brazing or the side of the bracket to roll or push stones. Because the oil pressure comes from the excavator, loader boom, arm, bucket, swing or slide operation, so the big and small arms will be damaged. At the same time, the breaker bolts may break, the bracket will be damaged, and the steel drill will be broken or scratched. Try to avoid using the breaker to carry stones. In particular, it is pointed out that steel drills are inserted into stones, and excavation must not be carried out.

4. Do not use the steel drill as a pry bar

If the steel drill is used as a pry bar when crushing stones, the bolts and steel drill may break

5. The excavator hammer lasts for no more than one minute

When beating hard rocks, the same beating lasts for no more than one minute, and then replace it with another beating work. Long-term beating operation will cause the oil temperature to rise, which will cause damage to the brazing bushing and damage the brazing bushing. Progress wear.

6. For long, hard rocks, they can start to break at the cracks or at the end, which makes it easier to break the rocks

7. The excavator breaker should work at the routine engine speed

When the hammer is used for crushing, the engine speed should meet the required fixed value. The engine speed exceeding the working requirements will not increase the striking force, but it will increase the oil temperature and cause equipment damage.

8. The excavator hammer cannot work in water and mud

It is not necessary to use the breaker in water and mud, otherwise, the piston or similar parts may rust and cause permanent damage. If it is necessary to work in water or underwater, the underwater breaker should be specially ordered.
