Installing a hydraulic breaker on an excavator does indeed have some impact on the machine, a concern for many owners. However, this impact can be significantly reduced with proper maintenance and use. In fact, incorrect operation and lack of proper maintenance are the main causes of excavator damage.
To minimize damage to the hydraulic system, the following key points should be noted during the operation of the hydraulic breaker:
During crushing operations, the high-frequency vibration of the breaker hammer significantly affects stress concentration areas such as the boom and arm. Prolonged continuous crushing operations can cause the gaps between these structural components to gradually increase, leading to machine vibration and increased noise. To minimize the impact of structural component deformation, the following points should be noted during operation:
The following operating methods should be avoided during crushing operations:
Avoid applying horizontal or upward impact forces during the crushing process, and ensure that the boom cylinder does not fully retract to its shortest position. This prevents rigid contact, keeps the working device structural components effectively buffered and protected by the hydraulic system, and thus prevents the working load from exceeding the structural capacity.
Operating the machine by rotation is prohibited, especially when the breaker's chisel is penetrating rock; avoid swinging the chisel. Because excavator components are highly sensitive to lateral impacts, this method of operation will generate 3 to 4 times the lateral impact force, severely impacting the service life of the components.
Pecking must not be performed by lowering the boom. This operation will generate significant additional impact loads, which may cause the instantaneous load to exceed the structural bearing capacity, resulting in unnecessary damage.
