Hong Kong’s first two Liebherr 550 EC-H 20 tower cranes have been used on the high speed Express Rail Link(XRL) project lifting 17t concrete linings down to the underground tunnels.
Hong Kong joint venture contractor Dragages-Bouygues and Penta Ocean Construction are both using the first Liebherr 550 EC-H 20 tower cranes for the lowering of 17t concrete linings down to the underground tunnels.
