Komatsu put its large HB365LC-3 hybrid crawler excavator through the paces at the recent ConExpo-Con/Agg convention, showing off the machine’s highly efficient capabilities to construction companies and other attendees. Komatsu says the excavator’s generator and motor system can provide an additional 40 horsepower (30 kilowatts) on demand and up to 15% more productivity in P mode. The HB365LC-3 can also deliver up to 20% greater fuel efficiency compared to a non-hybrid excavator design, while reducing carbon dioxide emissions by 20%, the manufacturer says.

Powerful, Efficient & Comfortable

The HB365LC-3 is powered by a Tier 4 Final Komatsu SAA6D114E-6 engine rated for 269 HP (201 kW) at 1,950 rpm. Its operating weight ranges from 81,791 to 85,495 pounds (37,100 to 38,780 kilograms), and it has a maximum bucket capacity of 2.56 cubic yards (2 cu meters).

The HB365LC-3’s auto-idle function can help owners save money by automatically reducing engine rpms after machine inactivity for four seconds. Further cost savings come thanks to the machine’s auto-idle shutdown, which operators can set to occur at intervals from five to 60 minutes. The excavator’s wide, spacious cab keeps operators comfortable throughout the workday with low-vibration damper mounting and a fully adjustable seat, full pressurization and automatic climate control, and a 69-decibel noise level.

Work Smarter

The HB365LC-3 Komatsu took to ConExpo was equipped with Smart Construction Retrofit, a guidance kit that helps reduce work for operators. Komatsu says the low-cost kit lets operators and managers alike access 3D design and payload data to help drive accuracy, control load volumes, and enhance operations. The kit obviates the need to configure a laser or bench each time the excavator moves and includes global navigation satellite system (GNSS) functionality that tracks the machine’s location and keeps track of the target grade.
