Anti-collision for mobile and tower cranes

The DCS 61-S automatically detects the movements of mobile machine and integrates the control of tower cranes. The unit is placed on tower and mobile cranes to communicate information via a radio network and constantly monitors and transmits the position of each of the machines using geolocation antennas.

When a mobile crane moves or repositions, the tower cranes device automatically knows its positions and the system creates an area of interference for all machines involved. The device calculates the distances between each element of the cranes (including the position of the cabin) in real time and in 3D, as well as the movement speeds. This is to intervene on the cranes control mechanism to ensure a slowing down, followed by a complete immobilization of the crane at a pre-set distance from the mobile crane.

For the mobile crane, the device emits an increasingly loud audible signal when approaching the prohibited overflight area. The DCS 61-S also gives the user the possibility to quickly create prohibited overflight areas in 3D directly on the screen by associating geometric shapes with perimeters and static obstacles.

The system continuously records and saves data related to events, movements and all crane parameters in order to view them directly on screen in the cabin and/or download them to a USB drive.

The DCS 61-S for mobile cranes was installed on the first site very recently, at Les Ardoines metro station, located to the east of Vitry-sur-Seine, in France. On this Grand Paris Express construction site, the mobile crane and the two tower cranes were fitted with the DCS 61-S. Another complication on this site was the close location of a tower crane and an overhead bridge crane in the vicinity.
