Correct operation will contribute to the rapid progress of crushing work. When the operation is insufficient, the strike force will not be fully exerted. At the same time, the impact force of the crusher hammer will reverberate to the crusher hammer body, guard plate and the operating arm of the engineering machine itself, resulting in damage to the above parts.
Conversely, when the operation degree is too large, which will cause the front of the construction machinery to be lifted, the construction machinery may suddenly tilt forward due to the crushing of stones. Make the body or guard plate of the breaker hit the stone violently and cause damage. It shall be avoided that the improper back vibration will be transmitted back to the construction machinery itself. Therefore, during the striking work, it should be confirmed that each operation is the correct loading. In addition, the breaker shall be completely inspected and maintained when not in use.
1. Operation direction of breaker
When running the crushing work, please make sure that the direction of the hitting point of the drill rod is perpendicular to the surface of the broken debris, and keep it as close as possible at any time. If it is inclined to the surface of the broken object, the drill rod may slide away from the surface. In this case, the tool will be damaged and the piston will be affected. When crushing, please select the appropriate strike point first. And strike after confirming that the drill rod is indeed stable.
2. Preparation before crushing
1) When the oil pipe is found to be loose, stop the operation immediately.
When the high-pressure or low-pressure hose of the breaker is excessively loose, please stop the operation immediately and check and repair immediately. At the same time, for the sake of caution, it is advisable to check whether there is oil leakage in other places at the same time. The operator shall strictly require to pay attention to the condition of the strike point at any time.
2) Avoid making the breaker blow without target
When the rock or object has been broken, please stop the striking action of the breaking hammer immediately. Continuous aimless impact will only cause loosening and damage to the screws of the precursor and main body, and even damage to the construction machinery. In case of aimless strike, in addition to improper insertion, shaking the breaker will also have an impact.
3) Do not push heavy objects or large stones with a breaker
Do not use the guard plate as a tool to push heavy objects during work, so it will only cause the breakage of guard plate screws and drill rods and damage the breaking hammer, and even the main cause of boom breakage.
4) Do not use the drill rod with shaking
During the crushing operation, if you try to use the drill rod by shaking, the main screw and the drill rod will be broken.
5) Do not use striking action to operate continuously for more than one minute.
When you strike continuously at the same point for more than one minute and fail to break the target, please change the selected point of the strike and try again. Trying to strike continuously at the same point will only cause excessive wear and tear of the tool.
6) When the target object is a large or hard stone, please choose to break it from the edge. No matter how big or hard the stone is, it is usually easier to strike from the edge.
7) When operating the breaker, please select the appropriate engine speed.
The crushing operation shall be carried out at the appropriate engine speed. Usually, when the speed of the engine is improperly increased to exceed the speed required for work, the strength of the striking force is not strengthened; by contraries; The temperature of hydraulic oil will rise rapidly, resulting in the decline of lubrication capacity and working capacity, which will damage the piston and air valve.
8) Do not break in water or mud
Except for the drill rod, other parts of the breaker should not be immersed in water or mud. If the piston and other parts with similar functions will accumulate mud marks, this will lead to the early loss of the breaker.
9) Do not drop the hammer onto hard rock
When the breaker falls down quickly and hits the hard stone surface, it will cause excessive impact damage to the breaker or construction machinery, causing damage to parts.
10) Do not operate when the hydraulic cylinder of construction machinery is fully extended or fully retracted
When the hydraulic cylinder of the construction machinery is fully extended or fully retracted, if the striking operation is carried out, the striking vibration will return to the hydraulic cylinder, resulting in serious damage to the construction machinery.
