The Caterpillar 302 CR is a compact mini excavator designed for construction, landscaping, utility, and site preparation work in confined spaces. It features a reduced tail swing design for improved maneuverability near walls, structures, and obstacles. The 302 CR is typically equipped with a hydraulic system for digging, grading, trenching, and attachment use, along with a comfortable operator station and intuitive controls. Its small footprint supports transportability and access to tight job sites. As part of Caterpillar's mini excavator lineup, the 302 CR is used for light to medium-duty excavation tasks where precision, stability, and space efficiency are important.
