An excavator, like any other mechanical machine, is subject to wear, either over time or as a result of operation. However, there are excavator parts that are exposed to early wear, e.g. due to working in difficult conditions. Even the parts that are cared for and maintained regularly will fail one day. Which of them refuse to obey the fastest?
In excavators, the track system is very important. However, the tracks, especially the rubber ones, deteriorate extremely quickly. It is estimated that track failures account for up to 1/5 of the most common excavator parts failures. This is due to operational reasons. The track materials age and corrode and the construction makes it difficult to lubricate the chains.
Excavator drive units break down just as often. They may include, among others to damage to the crank-piston system, similar to, for example, in passenger cars. That is why it is so important to regularly service the engine and make minor repairs. This avoids much higher costs in the future.
Cooling system and electrics
Cooling system malfunctions on excavators are also typical. This system must be looked after and controlled in terms of wear of its elements such as the fan and water pump.
Another system that is prone to failure is the electrical system. Its damage usually occurs in the winter. It is caused by too low temperatures and humidity outside. Unfortunately, this is fatal to the electrical system. It is necessary to regularly check that the cables are not too loose or exposed, and that the plugs are not frayed or corroded.
