Mini Excavator
Mini excavator is a small construction machine, usually used in construction, gardening, roads, water conservancy and other engineering construction, its main role is to excavate and transport earth and rock materials. Compared with large excavators, mini excavators are smaller, lighter and more flexible, and are suitable for construction in small spaces such as narrow sites, indoor or urban centers. Mini excavators are usually hydraulically driven, easy to operate and can be equipped with a variety of attachments, such as buckets, jaws and pile drivers, increasing their versatility.

Mini excavator common fault analysis

1. Engine can’t start: Possible causes include low battery, ignition system failure, fuel system failure, etc.
2. hydraulic system oil leakage: possible causes include hydraulic line wear, oil seal aging, hydraulic cylinder seal wear, etc.
3. excavator can not work normally: possible causes include circuit failure, hydraulic system failure, mechanical parts failure, etc.
4. High oil temperature: Possible reasons include dirty hydraulic oil, insufficient hydraulic oil, hydraulic radiator failure, etc.
