Caterpillar 323 vs Komatsu PC210LC-11

The Caterpillar 323 is about 8% heavier than the Komatsu PC210LC-11 (25,000 vs 23,240 kg), which usually means more stability and lifting capacity but higher transport weight.

The Caterpillar 323 has about 8% more engine power (129 kW (173 hp) vs 119 kW (160 hp)).

Beyond the numbers, compare local dealer support, parts availability and resale value for Caterpillar and Komatsu in your region: over the life of a machine they often matter more than small specification differences.

Strengths	+ Heavier counterweight (5.4 t) and frame give more lift capacity and stability than the 320 + Six-cylinder C7.1 engine with strong low-speed torque + Same factory Cat Grade, Payload, E-fence and Lift Assist technologies as the 320 + Still transportable like a 20-tonne machine in many regions + Excellent resale and dealer support	+ Six-cylinder 6.7-litre engine with plenty of torque at low rpm + Strong hydraulic flow (490 L/min) and quick 12.4 rpm swing for fast truck loading + Komtrax telematics fitted as standard; Komatsu CARE maintenance packages in many markets + PC210LCi-11 version offers the most automated factory machine control in the class + Up to 7% lower fuel consumption than the PC210LC-10, according to Komatsu
Watch-outs	− Same hydraulic flow (429 L/min) as the 320, so cycle-time gains come mainly from stability and bucket size − Higher price and fuel burn than the 320 − Heavier: closer to transport limits with a large bucket and wide shoes − Tier 4 Final / Stage V aftertreatment needs good DEF and fuel management	− KDPF plus SCR aftertreatment needs disciplined DEF and fuel handling − Slightly lower ISO crowd forces than some rivals on paper − Wide 2.98 m LC undercarriage means a wide load in many countries − Intelligent machine control (i-version) adds substantially to the price
