As an important construction machinery, the excavator long fronts arm can be said to be omnipotent for house demolition and digging. In many cases, the extension arm of an excavator is constructed in some complex geographical environment. It is inevitable that some minor failures will occur over time. It requires that we need to carry out regular maintenance work on the excavator long fronts arm, so what aspects should we start with? Let's take a look with the editor.

1. Check

Before using the excavator long fronts arm for construction, we need to strictly check whether the screws of each part of the machine are loose, the meshing and lubrication of each gear, and the wear and damage. During use, it is necessary to check the operating conditions of the engine. If there is any abnormal phenomenon, solve it in time to avoid affecting the later use.

2. Cleaning

Since the excavator long fronts arm is operated on the construction site most of the time, it is inevitable that dust and foreign matter will enter during the construction period. This requires us to clean each part of the structure of the extension arm of the excavator after the construction is completed to prevent foreign matter from entering. So as not to affect the use of the machine structure, so as to extend the service life of the machine.

3. homework

When using the long fronts boom for crushing operations, the drill rod should always be kept perpendicular to the surface of the object to be crushed. And make the drill rod tightly press the broken object, and stop the work of the breaker immediately after breaking to prevent runaway. Continuous aimless impact will cause damage to the precursor of the breaker and loosening of the main body bolts, which can damage the host itself in severe cases. When performing crushing action, do not use the drill rod by shaking, otherwise the main bolt and drill rod may be broken; do not drop the breaker quickly or hit hard stones, which will damage the excavation due to excessive impact Machine with extended arm.

4. lubrication

Lubricating the various parts of the long fronts arm can reasonably reduce the wear of various mechanical components. When performing lubrication operations, we also need to select qualified lubricating oil products according to relevant construction specifications to avoid the intrusion of impurities, and often check the lubrication of the machine Whether the system is normal.

As long as you pay attention to the above maintenance and maintenance skills, you can increase the life of the excavator long fronts arm, reduce our subsequent repairs and replacements, and help us save a lot of costs.
