AMCS Technologies Unveils the DCS 61-S Device for the Anti-Collision Sector

After several months of development and testing in real conditions, AMCS technologies unveils its anti-collision solution between tower cranes and mobile cranes available for international sales.

This is a world-first in the anti-collision world. Indeed, the anti-collision management of the AMCS technologies solution does not lie in the simple temporary neutralization of areas on the site prohibiting tower crane to work within a defined perimeter where the mobile crane could potentially be located. The new functionality of the DCS 61-S automatically detects the movements of the mobile machine and integrates the control of tower cranes.

The DCS 61-S placed on tower and mobile cranes communicate their information via a radio network and constantly know the position of each of the machines thanks to geolocation antennas. When mobile cranes move and reposition themselves in a different area to work, the tower crane devices automatically know their positions and the system creates an area of interference for the machines involved. The device calculates in real-time and in 3D the distances between each element of the cranes (including the position of the cabin) as well as the movement speeds. This is to intervene on the crane 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 keeps its two other essential functions for maintaining productivity and site safety

  • Zoning: the system 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.
  • Data loger: the DCS 61-S continuously records and saves data related to events, movements and all crane parameters in order to view them directly on the system screen in the cabin and/or download them to a USB key.

The DCS 61-S device is an evolving product, which has been designed in such a way as to integrate new functionalities such as anti-collision management between tower cranes and mobile cranes. After many requests from professionals in the sector, the research and development department of AMCS technologies developed this long-awaited solution.

The project started in February 2018. Several phases of laboratory tests in AMCS technologies offices and on site with their partners have been implemented in order to offer a viable, efficient solution that meets expectations.

A few months ago, the DCS 61-S for mobile cranes was installed on the first site, Les Ardoines metro station which is located to the east of Vitry-sur-Seine, in France. On this Grand Paris Express construction site, the mobile crane as well as the two tower cranes were fitted with the DCS 61-S. Another challenge was on this site, as it was interfering with another site with a tower crane and an overhead bridge crane.

The solution deployed by AMCS technologies has proven successful and demonstrated its necessity. Indeed, to avoid the many incidents and facing the increase in the use of mobile machinery on site, the DCS 61-S responds to safety and work issues. The system adapts to immediate decision-making and daily jobsite needs.

The DCS 61-S for mobile cranes is easy to install and program thanks to a screen installed in the crane operator’s cabin that provides him with all the information useful for operating the machine in real-time. This solution adapts to immediate decision-making and to the daily needs of construction sites thanks to the GNSS positioning system.

For this new innovation in the anti-collision sector, AMCS technologies won the Technical Innovation of the Year Award from the 2020 Tower Crane Trophies awarded at JDL last September.'
