Construction machine
View Patent ↗A construction machine with improved safety can include a high voltage cable for supplying power. The high voltage cable connects a storage devices to an electric drive that drives using power from a power generation device, which generates power using the drive of an engine, or from the storage device, which stores the power generated by the power generation device, is wired along the sides of a frame structural member that protrudes in a vertical direction. The frame structural member serves as an upright wall to adequately protect the high voltage cable. In cases in which, for example, the construction machine strikes an obstruction, or the like, the high voltage cable is adequately protected by the frame structural member.
1. A construction machine comprising:
a traveling mechanism;
a revolving body mounted on the traveling mechanism;
an engine;
a power generator generating power by drive of the engine;
a storage device storing power generated by the power generator via an inverter; and
high voltage cables connecting the power generator and the inverter,
wherein the revolving body includes a base frame and an A-frame supporting a boom,
the A-frame protrudes from the base frame in a vertical direction and extends from a front center portion to a rear center portion of the base frame,
the inverter and the storage device are positioned at a right front portion of the base frame,
the power generator is positioned at a right rear portion of the base frame, and
the high voltage cables extend from the power generator positioned at the right rear portion of the base frame toward the A-frame, further extend toward a front portion of the base frame along a substantial length of the A-frame, and are further connected to the inverter positioned at the right front portion of the base frame.
2. A construction machine comprising:
a traveling mechanism;
a revolving body mounted on the traveling mechanism;
a revolving electric motor driving the revolving body;
a storage device supplying power stored therein to the revolving electric motor via an inverter; and
high voltage cables connecting the revolving electric motor and the inverter, wherein the revolving body includes a base frame and an A-frame supporting a boom,
the A-frame protrudes from the base frame in a vertical direction and extends from a front center portion to a rear center portion of the base frame,
the inverter and the storage device are positioned at the right front portion of the base frame,
the revolving electric motor is positioned at a center portion of the base frame, and
the high voltage cables extend from the inverter positioned at the right front portion of the base frame toward the A-frame, further extend toward a rear portion of the base frame along a substantial length of the A-frame, and are further connected to the revolving electric motor positioned at the center portion of the base frame.
