Electric swiveling type construction machine
An electric swiveling type construction machine includes a lower travelling body, an upper swivel body which is turnably mounted on the lower travelling body, a boom in which one end is rotatably attached to the upper swivel body, an arm in which one end is rotatably attached to the other end of the boom, a working element which is rotatably attached to the other end of the arm, a brake mechanism which holds the upper swivel body, a swiveling motor which swivels and drives the upper swivel body, a state monitoring unit which monitors the state of the brake mechanism, and a controller which detects releasing of braking performed by the brake mechanism based on the monitor by the state monitoring unit. The swiveling motor does not generate a force until the controller detects the releasing of the brake.
