Product Overview

The Komatsu PC55MR is a top-tier 5.5-ton class zero-tail-swing compact mini excavator, originally manufactured in Japan. As the flagship model of Komatsu's MR mini excavator lineup, it features a reinforced heavy-duty chassis and extended working range, delivering significantly higher digging power and operational efficiency than smaller 3-4 ton models while retaining industry-leading confined-space maneuverability. It is widely recognized as the most cost-effective 5-ton+ mini excavator for urban municipal construction, indoor demolition, garden landscaping, pipeline trenching and small-scale earthmoving projects.

All our used PC55MR excavators are sourced from formal authorized import channels with 100% original core components, no structural collision or rollover history, and traceable regular maintenance records. Each unit undergoes a strict 80-point pre-delivery comprehensive inspection, including engine load test, hydraulic system pressure detection, track wear measurement and full electrical circuit verification. Purchasing this used Komatsu mini excavator only costs 35%-50% of a brand-new unit, with fast capital return and wide application scenarios, making it an ideal choice for small contractors, engineering rental companies and individual operators.

Core Product Advantages

• Original Komatsu 4D88E-6 four-cylinder water-cooled diesel engine, net power 28.5 kW (38 HP) @ 2400 rpm, robust low-end torque output, proven reliability and long service life, with fuel consumption of only 4.5-6 L per hour, adaptable to low-grade diesel in various regions and continuous heavy-load operation.

• Zero tail swing design with only 1060 mm rear swing radius, paired with left-right swing boom function; the machine can operate normally against walls, in narrow alleys, indoors and other limited spaces without tail collision risks, greatly improving construction safety and space utilization.

• Closed-center load-sensing hydraulic system (CLSS) with HydrauMind intelligent control, smooth and coordinated compound actions, excellent micro-operation precision for fine grading and precise trenching; standard auxiliary hydraulic pipeline, compatible with hydraulic hammer, auger, grab, ripper and other attachments for multi-purpose operation.

• Reinforced X-shaped chassis frame with 400 mm wide rubber track / steel track option, low ground pressure, no damage to asphalt pavement and lawn; two-speed travel mode with maximum speed of 4.6 km/h for flexible site transfer, gradeability up to 30°, adapting to various complex terrain conditions.

• Spacious ergonomic cab with wide entry design, adjustable shock-absorbing seat and centralized control layout, effectively reducing operator fatigue during long working hours; panoramic all-round visibility, equipped with safety lock lever to prevent misoperation and ensure construction safety.

• Transparent and reliable used condition: genuine unmodified hour meter reading, no abnormal oil leakage from engine, hydraulic pump and control valve; no cracks, deformation or welding repair traces on boom, stick, chassis frame and revolving platform; undercarriage components maintain good wear condition.

• Compact body with reasonable weight, can be transported by small truck or light trailer with low transportation cost; it can easily enter basements, courtyards, indoor buildings and other sites inaccessible to large excavators, expanding business scope for contractors.

• Full one-stop global export service: support third-party pre-shipment inspection by SGS, BV and other authoritative institutions; professional team handles customs declaration, shipping booking, container loading supervision, and provides complete set of export documents. Lifelong 24/7 online technical support for maintenance and fault troubleshooting.
