Product Overview – Reliable Used PC55MR-5 Mini Excavator for Global Projects
The used Komatsu PC55MR-5 excavator is a 5.26‑ton class mini crawler excavator, representing the largest model in Komatsu's MR-5 series[reference:0]. Powered by the Komatsu 4D88E-7 engine delivering 28.3 kW (38 HP) net power[reference:1][reference:2], this pre‑owned compact excavator delivers proven performance in confined construction sites, utility projects, landscaping, and demolition work[reference:3]. Every unit we supply retains 100% genuine OEM components – engine, hydraulic pumps, main control valves, and swing motors – with zero aftermarket substitutions. We guarantee a clean structural history with no major accidents or frame damage, backed by comprehensive service logs. With Komatsu's global dealer network ensuring rapid parts availability, this second‑hand PC55MR-5 offers a cost‑effective alternative to new machines, minimising downtime and maximising ROI for contractors, rental fleets, owner‑operators, and builders worldwide[reference:4].
Genuine OEM Parts – No Substitutes: Factory-original Komatsu 4D88E-7 engine, hydraulic pumps, and main control valves – a key differentiator of our certified used mini excavators.
Tight Tail Swing Design: Short-tail radius and swing booms that hug the machine, enabling efficient work in confined spaces where traditional excavators cannot operate[reference:5][reference:6].
Fuel-Efficient Performance: MR-5 series machines use up to five percent less fuel than their MR-3 predecessors, with no loss of performance or productivity[reference:7].
CLSS Hydraulic System: The Closed-centre Load Sensing System (CLSS) delivers precise control and optimal power to all movements, even when operating multiple functions simultaneously[reference:8].
EPA Tier 4 Final Compliant: Low-emission Komatsu engine with KDPF regeneration technology, delivering cleaner operation and improved fuel efficiency[reference:9][reference:10].
Full Maintenance Records: Every machine ships with a detailed service log – oil changes, filter replacements, and wear‑part servicing – ensuring complete transparency.
Versatile Attachment Compatibility: Standard proportional auxiliary line with dedicated piping for power tilt operation and hydraulic quick coupler, enhancing machine versatility[reference:11][reference:12].
Worldwide Parts Availability: Komatsu's extensive dealer network guarantees easy access to spare parts, keeping your pre‑owned excavator operational with minimal lead time.
