Product Overview

The Komatsu PC56-7 is a classic 5.3-ton short-tail-swing compact hydraulic excavator, manufactured by Komatsu with proven Japanese technology. As a benchmark model in the 5-6 ton class, it features a turbocharged diesel engine and closed-center load-sensing hydraulic system, delivering outstanding digging power and operational efficiency that rival many 6-ton excavators, while maintaining a compact body for flexible confined-space work. It is widely used in municipal engineering, road construction, landscaping, pipeline trenching, farmland renovation and small-scale earthmoving projects.

All our used PC56-7 excavators are sourced from formal authorized 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 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 S4D87E-1 four-cylinder water-cooled turbocharged diesel engine, net power 34.5 kW (46.9 HP) @ 2300 rpm, 2.434L displacement, strong low-speed torque output, stable and durable performance, with fuel consumption of only 5-6.5 L per hour, adaptable to low-grade diesel in various regions and continuous heavy-load operation.

• Short tail swing design with compact rear overhang, greatly reducing tail collision risk in narrow construction sites; matched with optimized working device layout, the machine balances excellent stability and flexible maneuverability, suitable for both open earthworks and confined municipal projects.

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

• Standard front dozer blade for site leveling, backfilling and slope finishing, improving integrated operation efficiency; heavy-duty X-shaped chassis frame with 400 mm wide steel track, strong impact resistance and long service life; two-speed travel mode with maximum speed of 4.1 km/h for flexible site transfer, gradeability up to 30°.

• Spacious ergonomic cab / canopy 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.

• Reasonable body weight and size, can be transported by medium truck or flatbed trailer with low transportation cost; it can easily enter residential areas, courtyards and narrow construction sites where large excavators cannot reach, 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.
