Public Housing Projects – Tseung Kwan O & Aldrich Bay

Completed Project

Focus on safety and speed with crane anti-collision system

To operate multiple cranes simultaneously on a multi-tower residential site, with some buildings only eight metres apart, was a critical challenge for Dragages.

Dragages pioneered an ‘Anti-collision and Zone Protection System’ which allowed the tower cranes to operate at optimal speed, while ensuring safety within the overlapping areas. Radio transceivers tracked the movement of the cranes ensuring that no two jibs collided during the construction process.

The same system was also adopted by Dragages’ parent company, Bouygues Construction, during the construction of the Stade de France, the main venue for the 1998 FIFA World Cup and the 2007 Rugby World Cup.
