Abstract
Since a stand including a plurality of supports and a top plate is built in on one side of a rear part of an upper frame of an upper rotating body as seen from an operator in a cabin, and a power storage device is installed on the top plate of this stand, the power storage device is arranged at the highest position among all the devices mounted in the upper rotating body. The power storage device is made up of a main body and a casing, and cooled down by taking cooling air into the casing.
Claims7
A hybrid working machine, comprising:
- a lower traveling body;
- an upper rotating body rotatably mounted on said lower traveling body;
- a working attachment provided on said upper rotating body;
- a cabin installed on one side of a front part of said upper rotating body where said working attachment is provided;
- and
- a power storage device serving as a power source for a generator motor mounted on said upper rotating body for performing a generator operation and a motor operation, said power storage device being installed on the other side of a rear part of an upper frame of said upper rotating body as seen from an operator in said cabin, wherein said power storage device is placed in a state that a lower surface of said power storage device is higher than any of an upper surface of an engine, an upper surface of the generator motor, an upper surface of a hydraulic pump, and an upper surface of a control valve, mounted on said upper rotating body.
