The reason why the excavator hydraulic piston is always bad

Published by HuiTong 2023-12-20

The working device is not fully recovered while walking

When the working device is not fully retracted, the bucket can easily hit the rock, and the piston rod of the excavator hydraulic piston will generate a large load, resulting in damage to the inside of the oil cylinder and cracking around the pin shaft.


The cylinder rod is extended to the limit for excavation

The excavator hydraulic piston is stretched to the end position. In this case, the working cylinder and the frame will generate a large load. The impact of the bucket teeth and the impact of each shaft pin will cause damage to the inside of the cylinder and affect other hydraulic components.

The rear of the crawler floats up for excavation work

The excavation work is carried out by utilizing the force of the rear of the excavator body floating. When the bucket is separated from the rock, when the vehicle body falls, a large load is generated on the bucket, counterweight, frame, slewing support, etc., and it is easy to cause damage.


Digging with walking force

After the hydraulic oil is mixed with water, it is easy to emulsification and deterioration. The emulsified hydraulic oil enters the hydraulic system and causes the parts to rust. Rust slag flows in the hydraulic system for a long time, the hydraulic pressure will be affected, and the action of the big arm and the bucket will become weak.


The excavator starts working without standing

On a gravel road with uneven road surface, when the excavator is not stopped, it will cause uneven stress on the lower frame and cause damage to the lower frame for a long time. It is best to pad some soil below to make the ground stable, and then work again.
