Komatsu PC450 expert review
Overview
Built 2007–2013, the PC450 LC-8 brings a net 257 kW (345 hp) SAA6D114E-5 engine into a 45 t chassis. It offers ~9.26 m dig depth and ~13.37 m reach, with manageable transport dimensions for a large excavator.
ECO mode and KOMTRAX keep fuel and maintenance in check.
Advanced features need operator know-how to exploit.
Performance & Efficiency
ECO and operating modes paired with KOMTRAX monitoring help optimize fuel and uptime. Smart hydraulics deliver consistent productivity.
In Comparison
Stronger and more capable than midsize units, but more agile and cost-effective than full-range mega excavators.
Verdict
For heavy-duty, high-production work, this is a strong pick. Not ideal for compact urban jobs or minimalist fleets.
