摘要： PURPOSE:To carry out a work in a wide range while avoiding an obstacle within the working radius of a horizontal jib type tower crane by arranging a travelable trolley in a main jib so as to allow a slide jib to extend and retract from and into the main jib in such a condition that the slide jib is confined to the slide jib. CONSTITUTION:When an obstacle is present, a signal indicating an extending and retracting distance of a slide jib 2 corresponding to a turn angle has been previously stored in a drive device for a drum 12. When a swivel unit is rotated so that the slide jib 2 approach the range of the obstacle, a drum 12 is turned in accordance with an indicated value thereof, and the slide jib 2 confining a trolley 3 at its distal end is slid into a main jib 1 so that the overall length is adjusted. Thus, the turning radius of the distal end of the jib can be freely adjusted within a range defined by the length of the slide jib 12. Accordingly, it is possible to efficiently carry out a work while detouring an obstacle around the crane or an entrance limited area.
