The main pump in an excavator is a hydraulic pump that converts the engine's mechanical energy into high-pressure hydraulic fluid to power the machine's movements. Its primary function is to supply pressurized fluid to the hydraulic system, which controls the boom, arm, bucket, and other attachments. This allows the excavator to perform tasks like digging, scooping, and lifting heavy materials. #hydraulic #SISTEM #hardwork | Excavator proyek
