Track Mounted Cranes ~ these machines can be a universal power
unit rigged as a crane (see page 178) or a purpose designed track
mounted crane with or without a fly jib attachment. The latter
type are usually more powerful with lifting capacities up to 45
tonnes. Track mounted cranes can travel and carry out lifting
operations on most sites without the need for special road and
hardstand provisions but they have to be rigged on arrival after
being transported to site on a low loader lorry.Cranes
