The excavator hydraulic breaker hammer is one of the most commonly used attachments for excavators, and is often used in mining, municipal and urban construction. During the construction process, if the breaker is used improperly, it will not only delay the construction period, but also easily damage the breaker. So what is the correct way to open the hydraulic breaker?

First of all, the excavator hydraulic breaker hammer cannot be started in the suspended state. Before the operation, the steel rod must be vertically pressed on the object to be broken and maintained under a certain pressure before breaking. During construction, if abnormal vibration is found in the hose, the operation should be stopped immediately. And contact the maintenance personnel for processing.

Continuing construction if ignored may cause damage to the accumulator and hydraulic pump. It should also be noted here that the excavator oil cylinder should not be fully extended during crushing, and the material should not be hit by dropping the excavator breaker hammer, otherwise the hydraulic excavator and the breaker may be damaged.

Secondly, when encountering hard and bulky materials, starting from the edge is the key to improving work efficiency. After the material is broken, the impact of the breaker should be stopped immediately to avoid harmful “empty hitting”. As the hydraulic oil temperature rises, the oil seal will be damaged, so continuous blowing for more than 1 minute cannot be performed.

Finally, the excavator hydraulic breaker is only used for crushing operations, and forcibly changing the use of the attachment will also cause “injury”~ Many users may use the breaker as a pry bar without paying attention to move the broken material or hook the material. The above methods will cause a certain degree of damage to the excavator and the breaker.

After construction, when maintenance begins. The old drivers will do three things after the crushing operation is over. First, check whether there is oil leakage in the hoses everywhere, and replace the hydraulic oil and filter element regularly. In the case of 50% use of the breaker, the hydraulic oil needs to be replaced every 1000 hours, and the filter element (hydraulic oil filter element/PPC circuit filter element/breaker oil return filter element) needs to be replaced every 250 hours.

Second, close the shut-off valve, remove the hose, and block the inlet with a plug to prevent dust from invading. Remove the steel chisel and place sleepers on the rear end to tilt.

The third is to spray rust inhibitor on the surface of the excavator hydraulic breaker hammer, and wrap it with waterproof paper or rain cloth to take waterproof measures. Knowing the above points well and applying what you have learned is the advanced road from the new to the old driver. Have you learned it?
