<P>PROBLEM TO BE SOLVED: To provide a device arrangement configuration for hybrid construction equipment, which miniaturizes the length of a chassis of the equipment, reduces power loss and electric noises of charging devices, and suppresses temperature rise of the same. <P>SOLUTION: In the hybrid construction equipment, a hydraulic pump (47) is driven by both an engine (41) and a generator motor (55). The hydraulic pump (47) is connected to the engine (41) via a PTO (46), and a regenerative motor (59) and the generator motor (55) are provided for the hydraulic pump (47) via the PTO (46). The regenerative motor (59) functions to regenerate electricity by returned oil from a hydraulic actuator. The generator motor (55) auxiliarily energizes the engine (41) as a motor to drive the hydraulic pump (47), and generates electricity by redundant torque of the engine (41) or the regenerative motor (59). Further in the construction equipment, the charging devices and high-pressure hydraulic devices are separately arranged from each other, and an inverter (61) is arranged on an upstream side of a fan (43) while the generator motor (55) is arranged at an edge of the engine, closer to the inverter (61). <P>COPYRIGHT: (C)2004,JPO |
