Top towers

The IC Tower Index, like its mobile and crawler counterpart, has grown in size over recent years. It continues to be dominated by two companies, but this year there is a change at the top as US-based Morrow Equipment moves into first place from second and Belgium's Arcomet moves in the opposite direction. Both Arcomet's and Morrow's fleet sizes have increased since 2004, but the US company has invested in cranes with higher lifting capacity, thus giving it the edge in the IC Index ranking.

Further down the top ten, companies continue to jostle for positions with MAN Wolffkran (Germany) and Jaso (Spain) swapping places.

The biggest mover in the top 20 is Kammerlander Baukranservice (Germany), which moves up four places to number seven.

New entrants in the IC Tower Index are AmQuip (US) - a company currently investing heavily in its tower crane operations, Netherlands-based Kranenbouw Bergeijk and Locabens of Brazil.

IC50 Towers listing In a similar way to the main IC50 Index, companies that own and/or rent out tower cranes are ranked by their IC Tower Index. Reflecting the widespread use of the tonne-metre rating method, this Index is calculated by adding together the maximum tonne-metre value for all tower cranes in the company's fleet. The figure is calculated by the crane-owning companies. If you would like an application form for your company for next year's listing, please contact IC.
