Patent ID: 8469136

Claim:
A hybrid construction machine comprising: an engine; a generator motor; a hydraulic pump; an engine-side mount device; and a generator-motor-side mount device, wherein the engine, the generator motor, and the hydraulic pump constitute a power unit, wherein the engine, the generator motor, and the hydraulic pump are connected in series, with the generator motor being disposed between the engine and the hydraulic pump and with a center of gravity of the entire power unit being positioned closer to the generator motor than is a center of gravity of the engine, wherein the engine-side mount device and the generator-motor-side mount device are disposed at the engine and the generator motor, respectively, with the center of gravity of the entire power unit being disposed therebetween, and wherein the power unit is supported on a body frame of the machine by the mount devices, and wherein an engine-side flange connected to the engine is provided at one side of the generator motor in an axial direction thereof, wherein a pump-side flange connected to the hydraulic pump is provided at the opposite side of the generator motor in the axial direction thereof, wherein a mount installation bracket extends between the engine-side flange and the pump-side flange and is mounted to both the engine-side flange and the pump-side flange, and wherein the generator-motor-side mount device is mounted to the mount installation bracket.
