T THE
French construction, energy and property development company GCC is using ten Liebherr flat top slewing tower cranes on a high profile eco development in Nanterre, in the western suburbs of Paris, France. The jobsite is called the ‘Arboretum’
development and is one of the largest timber new build sites in Europe. Once finished it will comprise 125,000 square metres of office and service space and will be primarily built of solid wood. The cranes being used on site
include: two 220 EC-B 10s; two 250 EC-B 10s; one 250 EC-B 12; two 285

EC B 12s; two 340 EC-B 12s; and one 370 EC-B 12. The cranes have different hook heights, jib lengths, and load capacities and will remain on site until mid-2023.
A 280 EC-H 12 high-top will additionally be used for the construction of the service centre. Due to the number of cranes
they have to be coordinated to avoid interference. To ensure this the cranes are fitted with anti-collision systems from the French manufacturer AMCS Technologies.
The machines also include Liebherr’s
LiUP operator lift. LiUP is designed to transport two people or a load of 200kg.
The cranes are lifting 20,000 cubic
metres of wood, which has been sourced from sustainably managed forests, as well as 55,000 cubic metres of concrete, with loads weighing up to several tonnes. The cranes position timber and
concrete elements such as posts, beams, columns, staircases and lifts. This, Liebherr says, is supported by the cranes’ Micromove fine positioning mode assistance system designed for greater load positioning accuracy. This also helps
