Komatsu America Corp. introduces the new HB3650LC-3 hybrid excavator

Improved hybrid technology, new-generation engine and total vehicle control systems combine to set new standards for fuel savings, performance and power

LAS VEGAS -- March 8, 2017 - Komatsu America Corp., a leading global heavy equipment manufacturer, introduced the new HB365LC-3 hybrid excavator at CONEXPO-CONAGG 2017. It features improved hybrid and total-vehicle-control systems, to help reduce fuel consumption by up to 20 percent, - depending on application - while maintaining or exceeding operating performance, compared to 36-ton, non-hybrid excavators.

“The new 36-ton-class HB365LC-3 excavator is built for power and production first, with the considerable fuel savings an added benefit,” said Kurt Moncini, Komatsu America senior product manager. “We applied everything we learned when we debuted the HB215LC-1, the world’s first fully-electric hybrid excavator in 2011. Now, we have the perfect balance of performance and fuel efficiency,” Moncini said.

Komatsu’s unique, fully-electric hybrid system uses an electric swing motor, which captures swing deceleration energy that would normally go unused, and makes it available to do work.  The energy captured during each swing cycle is stored in an ultra capacitor, which provides energy for the swing system.  The diesel engine also has a motor/generator for fast charging the capacitor when required, and to rapidly increase engine RPM from an ultra-low idle, for quick hydraulic response when boom, arm and bucket controls are activated.    

What makes the Komatsu system unique is the 100 percent electric swing system. The hydraulic power normally needed by the swing system is now completely available for boom, arm and bucket power, helping to improve digging cycle time and production.

To meet EPA Tier 4 Final certified requirements, the SAA6D114E-6, 269 HP engine combines a Komatsu Diesel Particulate Filter (KDPF) and Selective Catalyst Reduction (SCR) system with Diesel Exhaust Fluid (DEF) to meet NOx emission aftertreatment requirements.
