The HB365LC-3 hybrid excavator uses fourth-generation technology to increase production capabilities. The fully-electric hybrid system uses an electric swing motor, which captures swing deceleration energy that would normally go unused, and makes it available to power the boom, arm, and bucket. Stored power is transmitted to a motor/generator for fast charging the capacitor when required, and to rapidly increase engine rpm from an ultra-low idle of 750 rpm, for quick hydraulic response when boom, arm and bucket controls are activated.
A T4-F, 269-horsepower diesel powers the machine.
