小松 PC55

Compact and reliable, the 2015 Used Komatsu PC55 Excavator (2900H) delivers efficient digging, tight-tail performance and low operating costs for construction, landscaping and utility work. Engine: Komatsu 4D88E-7, weight 5.5t, bucket 0.3m³. The following section provides an expert overview of the used Komatsu PC55 excavator, focusing on operational capability, maintenance considerations and ideal use cases for contractors and equipment managers. This compact machine balances power and manoeuvrability, making it widely adopted for confined-site digging, urban utility work and precision landscaping. The Komatsu PC55MR is engineered for environments where a tight tail swing and responsive hydraulics are essential. With an operating weight around 5.5 tonnes and a robust Komatsu 4D88 series engine developing 29 kW, the machine delivers stable digging force (23.92 kN tear-out) and reliable cycle times. The short transport length and compact profile allow easy access to narrow sites while maintaining sufficient reach—up to 6.07 m horizontally and 3.8 m in digging depth—so routine trenching, small-scale excavation and foundation work can be completed efficiently. Komatsu’s hydraulic system in this series provides smooth, proportional control that benefits both productivity and fuel economy. For operators who rotate machines between tasks, the PC55 accommodates a variety of attachments including narrow buckets, hydraulic breakers, augers and thumbs, enabling rapid conversion from excavation to demolition or drilling tasks. The standard bucket capacity listed at 0.3 m³ offers a balance between load volume and precision; optional buckets in the 0.07–0.175 m³ range further increase adaptability for delicate work. Komatsu designs the operator environment to reduce fatigue and enhance situational awareness. The cab affords good visibility of the working area and controls are logically arranged for intuitive operation. Operator protection is specified as ‘Kb’, and routine inspections should verify ROPS/OPG status and seatbelt condition. Given the used condition of the unit, it is recommended to confirm the integrity of protective structures and hydraulic hoses during pre-purchase inspection. A major advantage of selecting a Komatsu model is the availability of parts and documented maintenance intervals. This 2015 unit with approximately 2,900 hours typically represents a mid-life machine when serviced correctly. Key service points include: engine oil and filter replacement, hydraulic oil and filter checks, undercarriage inspection (track width 400 mm), and regular greasing of pins and bushings. A pre-sale service history review can confirm oil change cadence and any major repairs, supporting long-term reliability.
