The Cat 303 CR is a 3-ton compact radius mini excavator. CR stands for Compact Radius. Positioned between the Cat 302 CR and Cat 304 CR, it balances excellent maneuverability in confined spaces with enhanced digging and breaking power. Application Scenarios: indoor wall demolition, villa landscaping renovation, municipal pipeline trenching, residential road repair, orchard land clearing, small foundation works, basement construction and farm sludge cleaning. It features retractable tracks and an ultra-short swing tail to avoid wall scratches. Delivering far greater power than 2-ton mini excavators, it achieves outstanding efficiency when breaking hard soil and weathered rock. It meets China Stage IV, EPA Tier 4 Final and Euro Stage V emission standards, making it exportable worldwide. Two configurations are available: a basic canopy and an enclosed pressurized air-conditioned cab. Standard factory fittings include retractable rubber tracks, offset boom and auxiliary hydraulic piping for breakers. It is a popular mainstream mini excavator for rental firms, municipal engineering and landscaping industries both domestically and internationally.
