The working principle of a crawler excavator mainly depends on its internal hydraulic system and crawler walking device. The hydraulic system usually drives the oil pump by an internal motor, which can be an electric motor or a diesel engine. Through the transmission of the hydraulic system, the excavator can achieve various complex excavation, loading and crushing actions. Its usage characteristics are as follows:

Off-road and terrain adaptability: The crawler excavator adopts a crawler walking device, with a large grounding area and strong off-road capability. This design allows it to operate stably in complex terrains such as muddy, wetlands, rugged mountains, and not easily get into trouble.

High stability: Due to the heavy weight of the crawler excavator and wide chassis, it has high stability. During the operation, even if a large external force impact is encountered, a stable operation state can be maintained.

Multifunctionality: Crawler excavators are usually equipped with a variety of equipment, such as buckets, breakers, grabs, etc., which can easily achieve multi-purpose functions of one machine such as digging, grabbing, loosening of soil, crushing, drilling, trenching, and digging.
