Crawler excavators are often equipped with powerful engines and advanced hydraulic systems, which enable them to perform a variety of complex excavation tasks. It has great traction and strong climbing ability, and can operate stably even in rugged mountains or muddy wetlands. In addition, the performance parameters such as excavation depth, excavation radius and rotation angle of the crawler excavator are usually high, which can meet the operating needs under different working conditions.

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.
