Komatsu recently demonstrated the capabilities of its HB365LC-3 hybrid crawler excavator at the Con Expo-Con/Agg convention. The excavator is equipped with a generator and motor system that can deliver up to 15% more productivity in P mode and an additional 40 horsepower (30 kilowatts) on demand. It also uses up to 20% less fuel than a non-hybrid excavator, while reducing carbon dioxide emissions by 20%.
Powerful Engine
The excavator is powered by a Tier 4 Final Komatsu SAA6D114E-6 engine rated for 269 HP (201 kW) at 1,950 rpm. Its maximum bucket capacity is 2.56 cubic yards (2 cu meters), and its operational weight is between 37,100 and 38,780 kilograms (81,791 to 85,495).
Efficient Features
The HB365LC-3 has several features that make it more fuel-efficient and cost-effective. The auto-idle feature automatically lowers the engine rpm after four seconds of inactivity, while the auto-idle shutdown can be scheduled to occur every five to sixty minutes, resulting in additional savings. The excavator also reduces cycle times and boosts production by sending all available hydraulic power to the boom, arm, and bucket when it swings.
Comfortable Cab
The excavator’s cab is designed to keep operators comfortable during the job. It features a fully adjustable seat, low-vibration damper mounting, full pressurization, automated climate control, and a 69-decibel noise level.
Smart Construction Retrofit
The Smart Construction Retrofit is a toolkit that lessens the workload for operators. It enables managers and operators to access 3D design and payload data to improve operations, drive precision, and manage load quantities. The kit eliminates the need to set up a laser or bench every time the excavator travels and comes with global navigation satellite system (GNSS) capabilities that monitor the machine’s location and record the target grade.
The Komatsu HB365LC-3 hybrid crawler excavator is a powerful, efficient, and comfortable machine that can help construction industry professionals work more effectively and economically. Its innovative features and technologies make it a valuable addition to any job site.
