A method for assembling a crane that comprises erecting an upright ballast mast with a back mast top slide that is movable along the ballast mast and constructing a back mast using the upright ballast mast. This comprises the steps of providing a back mast upper section, multiple back mast intermediate sections, and a back mast lower section. The method also comprises connecting a part of the back mast including at least the back mast upper section, and possibly further including one or more pre-connected intermediate sections, to the back mast top slide. The part of the back mast that has been connected to the back mast top slide is stepwise extended by attaching further back mast intermediate sections and the back mast lower section. During the extension of the back mast the back mast top slide is stepwise raised along the upright ballast mast.
