PURPOSE: A crane having an aerogenerator is provided to actively utilize the length of the crane and a space occupied by the crane with a photovoltaic power generator, thereby improving a utilization rate thereof. CONSTITUTION: A crane includes a pair of vertical frames(100), a horizontal frame(200), and an aerogenerator(300). The aerogenerator includes a nacelle part, a hub, multiple blades, a main shaft, a moving shaft, a link part, and a connecting part. The moving shaft is capable of linearly moving inside the hollow main shaft, and the blades are coupled to one side of the moving shaft. The link part between the moving shaft and the blade axially rotates the blade according to the linear movement of the moving part in order to vary the tilt angle of the blade. The connecting part inside the main shaft is installed at the other side of the moving shaft, and linearly moves the moving shaft. A photovoltaic power generator(400) is installed at the horizontal frame. |
