Excavators Go Hybrid

Excavators are continuing to evolve for the construction industry, offering new ways to improve performance at the jobsite.

As one example, Komatsu America Corp., introduced the HB365LC-3 hybrid excavator. It features improved hybrid and total vehicle-control systems to help reduce fuel consumption by up to 20%, depending on application, while maintaining or exceeding operating performance.

The unique, fully-electric hybrid system uses an electric swing motor, which captures swing deceleration energy that would normally go unused, and makes it available for 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 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.

This system has a 100% electric swing system. The hydraulic power normally needed for 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 and Selective Catalyst Reduction system with Diesel Exhaust Fluid to meet NOx emission after treatment requirements.

This is one example of the new tech being used in equipment. There are many options available to use on the jobsite.
