Bad Habit Of Novice Excavator

In many people’s eyes, the excavator is a kind of construction machinery with high reliability and stability, but this idea is wrong. Although the excavator is used for rough work, it is also a kind of precision machinery. If you don’t pay attention to the details, it will cause serious damage to the parts of the excavator, and these big guys are really expensive to repair.

1.Work without preparation

In order to improve work efficiency, many novices often start working immediately as soon as they enter the construction site. In fact, this is wrong. After entering the operation area, they should first check the surrounding operation environment and stop the machine on flat land as much as possible, because if the inclination angle of the excavator is too large, the engine oil pressure will not be supplied, and doing so for a long time will cause damage to the engine due to continuous high temperature, And after it is stable, make a small mound in front of the crawler to improve the stability of the excavator.

2.The hydro-cylinder extends to the limit

Many novices like to extend the big and small arms to the limit for work, but this way will produce a large load on the oil cylinder, which will cause damage to the oil cylinder for a long time and serious failure of other parts.

3.Floating operation at the rear of track

When facing objects with high hardness, many novices will float the back of the excavator to increase the excavation strength, which will increase the operation efficiency, but it will increase the load on the pin shaft and weak parts of the excavator. A long time will cause the deformation of the frame, bearing damage or fracture of the excavator.

4.Transfer and stop too hard

Some masters like to turn and stop suddenly when working, but it is very easy to cause the hydraulic system to jam, and the rotary table bearing is also easy to be damaged.
