<p>PURPOSE:To provide a constructing machine capable of realizing the lighting of the top end part of a working machine and the rotating directional lighting of a revolving superstructure with a smaller number of lighting equipments. CONSTITUTION:Lighting equipments 10a, 10b rotatable within a vertical surface and rotatable within a horizontal surface according to a drive signal outputted from an arithmetic means 26 are provided on a revolving superstructure 2, and on the basis of the signal outputted by the operation of a turning lever 27, it is judged whether the revolving superstructure 2 turns right or left. In the case of right turning, the lighting equipment 10a independently turns right to light the right turning side in advance of the turning of the revolving superstructure 2, and the lighting equipment 10b integrally turns with the revolving super-structure 2 to light the bucket part of a working machine 3. In the case of left turning, the lighting equipment 10b independently turns left in advance of the turning of the revolving superstructure 2 to light the left turning side, and the lighting equipment 10a integrally turns with the revolving superstructure 2 to light the bucket part of the working machine 3.</p> |
