Liebherr R 920 Litronic Vs CAT 321 Excavator Price, Technical Specifications & Features
The CAT 321 is a 21-ton hydraulic crawler excavator built for pipeline work, road foundations, and medium-scale earthmoving jobs across India. It is powered by a Cat C3.6 engine delivering 134 HP at 2,000 rpm. The electrohydraulic system works in sync with the engine, moving more material while burning less fuel per cycle. Weighing approximately 19,300 kg, this heavy-duty CAT excavator provides a stable digging platform on both firm and uneven ground. The maximum digging depth of 5,970 mm suits most foundation, trench, and utility excavation tasks. A bucket capacity of 1.0 m³ ensures steady material throughput per pass. Boom and stick regeneration circuits sharpen cycle times and lower fuel draw simultaneously. Eco mode cuts consumption further, lift and dig capacity remain fully intact. The X-structure lower frame spreads load evenly across the tracked undercarriage. Cat VisionLink telematics allow remote monitoring of fuel use, location, and maintenance alerts. The 370-litre fuel tank supports long shift operation without mid-day refuelling stops. A one-year warranty covers materials and workmanship through authorised Cat dealerships. The CAT 321 excavator price in India ranges between Rs. 75 to 85 lakh. This excavator from Caterpillar Construction Equipment is best suited for infrastructure contractors and site developers managing road, canal, and foundation projects.
