A few weeks ago, an AMCS technologies DCS 61-S anti-collision system was commissioned between a Demag AC55-3 mobile crane and one of the four Wolff 7534.16 tower cranes on the construction site of the operations center for lines 16 and 17 of the Grand Paris Express in Aulnay-sous-Bois.

For several weeks this mobile crane worked within the range of action of one of the tower cranes. The DCS 61-S was chosen as the solution to address safety and work issues.

The DCS 61-S automatically detects the movements of the mobile machine and integrates the control of tower cranes.

The systems placed on tower and mobile cranes are connected via a radio network and constantly exchange all sensor information. Due to mobile antennas, every DCS 61-S connected in the anti-collision network knows the positions of the mobile crane’s elements at any moment.

The activation of the interference between the mobile crane, which will remain on site until next April, and the three other tower cranes will come into effect soon. A second mobile crane, Liebherr LTM 1100, has joined the site and will also interfere with all Wolff tower cranes.
