Excavator drag sprocket oil leakage

The four-wheel belt is very familiar to the old drivers who deal with excavators every day. Generally, the four-wheel belt is a vulnerable part. If it is broken or worn out, you can just ask the boss to replace it.

Excavators often "drop the chain"

Excavator off-chain, commonly known as off-chain, means that the track is separated from the track formed by the drive wheel, supporting roller, guide wheel, and supporting sprocket. Since the excavator often works in some harsh environments, and the crawler is a part that directly contacts the ground, when the working ground is bad and the operation is improper, it will often cause the chain to be disconnected. Let's list a few common reasons below, and analyze how to avoid dropping the chain.

Little knowledge about excavators

The small arm of the excavator is a laborious lever, and the pin in the middle is the fulcrum. Up is the big arm, down is the forearm! The longer the arm, the less effort it takes, on the contrary, the more effort it takes! At this time, the boom is the longest, so the digging force of the forearm is the largest at this angle!

Komatsu chassis parts - guide wheel replacement method

The guide wheel is an important part in the walking system of large-scale construction machinery such as excavators. It is installed on the track to guide the track. Its main function is to guide the correct winding of the track.

Fault diagnosis of tension spring buffer device of excavator accessories!

In order to ensure that the crawler running device can work normally and reduce the impact load and extra power consumption during walking, each crawler is equipped with a tensioning device to maintain a certain tension of the crawler. The tensioning device of the track must use the guide wheel to realize the tension of the track. However, after a certain period of time, the excavator tension spring buffer device will also fail, thereby affecting the normal operation of the excavator.

do you know? Rollers can also be buttered!

Many excavator drivers have encountered oil leakage from the rollers, and most friends will ignore them and wait for the rollers to be polished and replaced with new ones. Although it is almost impossible to repair after an oil spill, the rollers can also be buttered! It can continue to be used for 2000 hours after buttering is the same as if there is no oil leakage.
