In the lower weight to be mounted on the system, there is the following problem with the integrated large-capacity lower weight having no folding structure. (1) When the lower weight is long in the front-rear direction of the machine, the position of the suspension lug b for suspending the lower weight a is separated from the machine body when the lower weight a is mounted as shown in FIG. Therefore, by connecting the crane main jib c and the lower weight a with a wire rope d,
The weight a can be detached by itself (FIG. 9). However, a working space in front of the crane cannot be secured. (2) When the lower weight is short in the front-rear direction of the machine, the position of the suspension lug b for suspending the lower weight a approaches the machine body when the lower weight a is mounted. For this reason, the above-mentioned detachment by itself cannot be performed due to insufficient stroke. Therefore, an auxiliary crane is required for mounting the lower weight a (FIG. 10).
