Points for attention of breaker operators

2022-12-14

whenHammerDuring the operation period, operators need to pay attention to the following aspects:

1. When the hydraulic rubber hose of the breaker vibrates strongly, the work should be suspended

It should be checked whether the high-pressure and low-pressure hoses of the breaker vibrate too strongly. If such a situation occurs, it may be a fault, and you should immediately contact your local designated office for after-sales maintenance services. Check relevant Whether there is oil leakage at the hose joint, if there is oil leakage, the joint should be tightened again. During the working period, it should be estimated whether there is a large amount of drill rod, if there is no surplus, it must be stuck in the lower body, the lower body should be removed, and the parts should be checked Should common faulty components be repaired or replaced?

2, Pause work (to prevent excessive empty strike)

If the stone is broken, the hammering should be stopped immediately. If the hammering continues, the bolts will fall off or crack, and even the excavator and the cutting machine will be adversely affected. When the penetration of the breaking hammer is unreasonable or the steel drill is used as a When prying the bar, an empty strike situation will also occur.

3, Breaking hammers cannot be used to move stones

It is not allowed to turn or push the rocks by using the steel drill end or the side of the bracket. Because the oil pressure comes from the excavator, loader arm, small arm, bucket, swing or roll operation, the large and small arms will be damaged, and the At the same time, the bolts of the breaker may crack, the bracket will be damaged, and the steel drill will be cracked or scratched. Try to avoid using the breaker to carry the stone. In particular, it is emphasized that the steel drill is inserted into the stone, and the excavation must not move.

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

If the chisel is used as a pry bar when crushing rocks, the bolts and chisel may crack

5. When working on hard rock, the continuous tapping should not exceed 1 minute, and the same tapping should not exceed 1 minute continuously, and then change to another tapping work. Long-term tapping operation will also cause high oil temperature, which will cause steel The brazing bushing is damaged and the brazing progress is worn.

6. For long, hard rocks, they can be broken from their cracks or tails, which is easier to break the rocks.

7. The breaker needs to work under the routine engine speed ratio. Exceeding the engine speed ratio required for work will not increase the striking force, but it will cause high oil temperature and cause equipment damage.
