Abstract:
A shovel according to embodiments of the present invention includes: a lower traveling body; an upper swivel body that is rotatably mounted on the lower traveling body; an attachment that is configured by a boom, an arm, and an end attachment; an engine that is mounted on the upper swivel body; a motor generator that is able to assist the engine; a power storage system that is mounted on the upper swivel body; a swiveling motor that is driven by electric power from the motor generator and the power storage system; temperature detection units; and a control device. The control device switches a control mode in a case where at least one of a temperature relating to the motor generator, a temperature relating to the power storage system, and a temperature relating to the swiveling motor, detected by the temperature detection units, is higher than a predetermined temperature.
