Generally, truck-mounted tower cranes are completely self-contained and can be driven along roads. The advantage of mobile tower cranes lies in great inward reach without the long jib which would normally be required to reach over the top of the structure. On the other hand, the crane service would be disrupted whenever work must be done on or near the track. However, the height requirement should not exceed the free-standing height as recommended by the manufacturer. Rail-mounted tower cranes have a larger area of coverage as they can travel along their tracks carrying their rated loads. They can also be extended beyond this limit by tying the crane back to the supporting structure. They can be set at varying heights up to their maximum free-standing height. ![]() Static tower craneĪ tower crane with a static base only occupies a limited area but is able to cover, from its fixed position, all points at which loads are to be handled within the maximum slewing radius. The operating characteristics of a tower crane are largely determined by its type of mounting, type of tower and type of jib.
