About the Komatsu PC360
The Komatsu PC360 is a 35-tonne class hydraulic excavator, produced continuously since 2002 and currently in its PC360-11 generation. It is powered by a Komatsu SAA6D114E-6 engine producing 257 hp and operates a 1.6 m³ standard bucket with a maximum digging force of 24,500 kg. The PC360 fills the role of heavy production excavator, suited to projects where a 20-tonne machine cannot deliver sufficient volume and a 50+ tonne machine is oversized. The PC360-11 features Komatsu's KOMTRAX Plus telematics and an optional intelligent Machine Control grade control system.
Typical applications
The PC360 is a production workhorse on large European civil engineering projects. German road and motorway contractors use it for bulk topsoil stripping, drainage channel excavation, and deep foundation work on bridge abutments. Dutch harbour and waterway contractors deploy it for dredging and dock excavation, often fitted with a long-reach arm and wide dredging bucket. Belgian contractors working on large industrial estate earthworks favour it for its combination of bucket capacity and reach that allows efficient loading of 30-tonne dump trucks in one or two passes.
What to look for when buying used
At 36,000 kg, the PC360 imposes significant forces on its undercarriage. Inspect the track frames for cracks near the idler and sprocket mounts, and check track link pitch measurement carefully — wear above 3% elongation indicates imminent chain replacement is needed. The main hydraulic pump and swing motor are the most expensive components to replace; request hydraulic system pressure test data and oil sample analysis. The PC360's boom and arm cylinders experience high cycle loads on production excavation work — inspect the cylinder rod surfaces carefully for scoring and seal leaks.
Market context
The PC360 competes with the Caterpillar 336 and Volvo EC380 in the 35-tonne class. Komatsu's reputation for engine durability and strong dealer support makes the PC360 a preferred choice for buyers who prioritise long service life. The German and Dutch markets show the strongest demand for this size class, driven by ongoing infrastructure and waterway maintenance programmes. Prices for the 2015–2022 generation are currently at fair market levels, with GPS-equipped intelligent Machine Control variants commanding a premium of 10–20% over conventional machines.
Common problems at high hours
The twin main hydraulic pumps on the PC360 are the highest-value wear items, with a pair replacement costing €18,000–24,000. Above 8,000 hours in production excavation, pump flow rates decline measurably — request a flow-rate test at rated RPM before purchase. The boom foot pin bores elongate under the heavy loads this machine handles, requiring re-bushing at 6,000–8,000 hours (€3,500–5,000 per side). According to Zeppelin service engineers in Germany, the PC360-10 generation suffers from EGR cooler cracking at 5,000–7,000 hours, leading to coolant loss and potential engine overheating — repair cost is approximately €4,000–6,000. The swing ring bolts should be checked for correct torque at every major service; bolt stretching on high-cycle production machines is a documented issue.
Resale value trajectory
The PC360 holds value solidly in the European 35-tonne excavator segment, though not as strongly as the smaller PC210 due to a thinner buyer pool. Machines from the 2016–2020 production window have retained approximately 48–55% of their original list price after five years of service. The German market drives the strongest residual values, with Dutch waterway contractors as the secondary demand centre. GPS-equipped iMC variants retain an additional 10–15% over standard machines, reflecting the growing requirement for machine control on major infrastructure tenders. Export demand to the Middle East and Southeast Asia supports pricing on higher-hour units that have reached the end of their primary European service life.
Alternatives in this class
The Caterpillar 336 is the primary competitor — its Next Generation platform (2018+) offers superior fuel economy in E-mode and better factory-integrated grade control, making it the preferred choice for technology-forward contractors. However, the PC360 is widely regarded as having a more durable engine platform for sustained high-load production work. The Volvo EC380 offers the best cab ergonomics in the 35-tonne class and strong tiltrotator compatibility, though parts costs run approximately 10–15% higher than Komatsu equivalents in the Benelux. For buyers who can accept a slightly older platform, the Hitachi ZX350 provides strong hydraulic performance at lower acquisition prices.
