Mobile crane

A mobile crane comprising:

• (a) a travelling base structure adapted to allow the mobile crane to travel over a surface;
• (b) a revolving superstructure mounted on the travelling base structure;
• (c) a boom and a backmast, wherein the boom and the backmast are hinged about an associated pivot axis horizontal to the revolving superstructure;
• (d) a main load hoisting means associated with the boom for hoisting a load;
• (e) a superstructure ballast, wherein the superstructure ballast is supported by the revolving superstructure;
• (f) a removable and repositionable superlift ballast with connection means suspending the superlift ballast, and a first and second superlift ballast support means, wherein the connection means connect the superlift ballast to the backmast;
• and
• wherein the first and second superlift ballast support means are adapted to support the superlift ballast on the travelling base structure so that the superlift ballast is transportable with the mobile crane when the mobile crane is moved from one job site to another while being supported by the travelling base structure, forming the mobile crane with the removable and repositionable superlift ballast.
