The Caterpillar 320E L RR is a hydraulic excavator in Caterpillar's 20-ton class, designed for general earthmoving, trenching, utility work, and site preparation. The "L RR" designation refers to a long undercarriage with reduced tail swing, improving stability and allowing operation in confined jobsite areas. The 320E L RR is typically equipped with a Caterpillar diesel engine, hydraulic system, and operator cab designed for productivity and visibility. Common attachments include buckets, hammers, and grapples. This model is used in construction, roadwork, and material handling applications where reach, balance, and maneuverability are required.
