GMA and GME tower cranes

Tower cranes can be used in a wide variety of sectors, from construction sites to harbors, and can therefore be found on both building sites and shipyards.

In construction, they are used to move and lift materials (cement, sand, concrete, steel, etc.) and prefabricated elements of considerable volume and weight.

They are equipped with a metal boom and various fittings such as a hook, a block, cables and so on. The concept dates back to the end of the Second World War.

This article deals with two types of crane: tower cranes with component or assembly mounting, known as GMEs, and automated mounting cranes with hydraulic or mechanical (winches and cables) deployment, known as GMAs.

The choice of crane is crucial to the success or failure of a project, whether in terms of the quality of the work or the time and cost involved.

This article presents the main characteristics of GME and GMA tower cranes in section 1 , details their installation process in section 2 , explains on-site maintenance in section 3 , develops the safety rules specific to this type of crane in section 4
