CAT 306E2 CR is Caterpillar’s classic 6-ton compact radius mini crawler excavator. It is powered by Cat C2.4 DI Turbo direct injection engine with Tier4 Interim / Stage IIIA emission standard, only DOC after-treatment, no urea required, with good tolerance to low-quality diesel, suitable for overseas markets such as Africa, Southeast Asia and Latin America. Featuring CR compact radius design plus swing boom, the rear overhang is limited during slewing, safe to work close to walls and fences, ideal for narrow streets, yard and indoor sites. Original CAT HDH load-sensing hydraulic system delivers precise flow control, fine metering and smooth combined movements. Standard dozer blade enables easy backfilling and grading. It is widely used for landscaping, yard renovation, orchard trenching, municipal pipe trenching, septic tank construction, small foundation excavation, indoor demolition and light breaking. Factory pre-installed bi-directional auxiliary hydraulic lines support quick hitch, compatible with hydraulic breaker, auger and grapple.
