The breaker hammer may be the most commonly used attachment of the excavator besides the bucket. With the hammer, the excavator can make more money while working, but everyone also knows that “beating” is very harmful to the excavator itself, especially is an incorrect operation.
The following points should be paid attention to when operating the excavator breaker:
(1) Every time you use the breaker, you should first check whether the high-pressure or low-pressure oil pipe of the breaker is loose; at the same time, for the sake of caution, you should always check whether there is oil leakage in other places to avoid the oil pipe falling off due to vibration and causing failure. .
(2) When the breaker is operating, the drill rod should always remain perpendicular to the surface of the object to be broken. And make the drill rod press the broken object tightly. After crushing, the breaker hammer should be stopped immediately to prevent empty hitting. Continuous aimless impact will cause damage to the front body of the breaker and loosening of the main body bolts. In severe cases, the main engine itself may be injured.
(3) When carrying out crushing, do not shake the drill rod, otherwise the main bolt and drill rod may break; do not drop the hammer quickly or hit it hard on hard stones, otherwise it will be subject to excessive impact. And damage the breaker or the main engine.
(4) Do not carry out crushing operations in water or mud. Except for the drill rod, other parts of the breaker body should not be immersed in water or mud. Otherwise, the piston and other parts with similar functions will be damaged due to accumulation of mud. This causes premature wear of the breaker hammer.
(5) When breaking a particularly hard object, you should start from the edge first, and do not hit the same point continuously for more than 1 minute to prevent the drill rod from burning or the hydraulic oil from overheating.
(6) Do not use the guard plate of the breaker hammer as a tool to push heavy objects. Since the backhoe loaders are mainly small machines and are light in weight, if they are used to push heavy objects, the breaker hammer may be damaged in a minor case or the main engine may be damaged in a serious case. The boom broke, and even the main engine rolled over.
(7) Perform operations when the hydraulic cylinder is fully extended or fully retracted, otherwise the impact vibration will be transmitted to the hydraulic cylinder block and thus to the host machine.
Breaking hammer maintenance
Since the working conditions of the breaker are very harsh, correct maintenance can reduce machine failures and extend the service life of the machine. In addition to timely maintenance of the host, the following points should also be noted:
1. Appearance inspection
Check whether the relevant bolts are loose; whether the connecting pins are excessively worn; check whether the gap between the drill rod and its bushing is normal, and whether there is oil leakage, indicating that the low-pressure oil seal is damaged and should be replaced by a professional.
2. Lubrication
The lubrication points of the working equipment should be lubricated before operation and after 2 to 3 hours of continuous operation.
3. Replace hydraulic oil
The quality of hydraulic oil varies depending on the working environment. A simple way to judge the quality of the oil is to observe the color of the oil. When the oil quality deteriorates extremely seriously, the oil should be drained and cleaned. Inject new oil into the oil tank and oil filter.
