Latest company news about Maintenance method of excavator hydraulic breaker

People have to be middle-aged. This is true for people, especially as a kind of equipment in the construction machinery industry! The working environment of excavator hydraulic breaker is harsh, the impact force is large, and the shape and hardness of the broken objects are different. All these are factors that affect the "health" of the breaker. Therefore, in addition to cracking and sharpening, the excavator hydraulic breaker also has the need to maintain health, and there is also a way to maintain health. So, in order to better extend the service life of the breaker, how should the breaker be operated correctly in daily use?

The crushing work must be done well, and the inspection work must not be less

First check whether the hydraulic oil is within the scale line of the dipstick. When the excavator hydraulic breaker is in a vertical static state, tap lightly with a hammer to check whether the bolts, nuts and hoses are loose. If there is any looseness, tighten it and reinforce it. Then, check the wear status of the steel drill bushing. First, ground the excavator hydraulic breaker and turn off the excavator's engine.


Then measure the gap between the steel drill and the steel drill bushing, and exchange before the maximum wear limit (8mm). If the gap exceeds the service limit (8mm), the steel drill needs to be pulled out to measure the inner diameter of the steel drill bushing. If the inner diameter of the steel drill bushing exceeds the wear limit, a new steel drill bush must be replaced. If the inner diameter of the steel drill bush does not exceed the wear limit, a new steel drill must be replaced. After all the inspection work is completed, the preparatory work before the excavator hydraulic hammer operation can be carried out.

If you want more "smooth" construction, don't forget to beat butter frequently

When the excavator hydraulic hammer is working, it is recommended to add butter every 2 hours. Warm up the machine after beating the butter.

Select the crushing mode in the monitoring panel, and confirm that the shut-off valve is open, and start the engine. Attention, don't rush into crushing operation when the engine is just started.

Before the formal operation, you need to perform the warm-up operation, slowly operate the boom and stick for 5 minutes, and observe the temperature displayed by the hydraulic oil temperature monitor until the oil temperature is maintained at 40-60 degrees. In cold areas, the warm-up time should be extended appropriately. After the warm-up operation is completed, the excavator can go to work with full energy.
