HL185 Durable Life Mining Spare Parts All Series Excavator Heavy Duty Concrete Rock Stone Hydraulic Hammer Breaker

Operation precautions

During the work of the breaker, the operator should pay attention to the following points:

1) Stop work when the hose vibrates violently

The high-pressure and low-pressure hoses of the breaker should be checked for excessive vibration. If that is the case, there may be a malfunction and you should contact your local service immediately for repair service. The hose joints should be further checked for oil leakage. If there is oil leakage, the joints should be re-tightened. During the operation, it should be visually checked whether there is any allowance for the steel drill. If there is no allowance, it must be stuck in the lower body. The lower body should be removed to check whether the parts should be repaired or replaced.

2) Stop the operation (avoid excessive air strikes)

Hammering should be stopped as soon as the stone is broken. If the air strike is continued, the bolts will loosen or break, and even excavators and loaders will be adversely affected. When the breakdown force of the breaker is improper or the steel drill is used as a pry bar, the phenomenon of empty strike will occur. (The sound of the hammer will change when the breaker hits empty)

3) The breaker cannot be used to move rocks

Do not roll or push stones with a steel drill or side of the stand. Because at this time the oil pressure comes from the excavator, the loader boom, and the forearm. Bucket, swing or slide operation, so the big and small arms will be damaged, and the breaker bolts may be broken, the brackets may be damaged, the steel drills may be broken or scratched, and the breaker should be avoided to remove stones. In particular, it is pointed out that the steel brazing is inserted in the stones, and you must not walk when excavating.

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

Bolts and drills may break if the drill is used as a pry bar when crushing stones

5) Do not keep hitting for more than one minute

When hitting hard rocks, the same hit should not last more than a minute, and then switch to another hit.

Long-term beating operation will cause the oil temperature to rise, which will lead to damage to the brazing bushing and wear of the brazing progress.

6) For long and hard large stones, it can start to break at the cracks or ends, so that it is relatively easy to break the stones.

7) The breaker should be operated at the routine engine speed

When the breaker is broken, the engine speed should meet the specified fixed value. Exceeding the engine speed required for the operation will not increase the striking force, but it will cause the oil temperature to rise and cause equipment damage.

8) The breaker cannot work in water and mud

Do not use the breaker in water or mud, otherwise the piston or similar parts may rust and cause permanent damage. Submerged breakers should be specially ordered if working in or under water is required.

9) Do not let the breaker fall directly to break the stones

If the breaker falls directly to the gravel, the breaker or excavator will bear excessive force, which will easily damage the parts of the excavator and loader.

10) When the stroke of the cylinder rod on the excavator boom is the largest, please do not strike

When the excavator and loader oil cylinder rod has the maximum stroke (the cylinder rod is fully extended or retracted), crushing rocks will damage the oil cylinder and various parts of the excavator and loader.
