Crawler Crane Manages High Alpine TerrainPanorama

Crawler Crane
Manages High
Alpine Terrain

A Liebherr LTR 1060 was driven around tight bends and on gradients of up to 40 percent to the site at an altitude of 2020 meter to extend a tunnel on the Gornergrat railway in Zermatt in the Swiss Canton of Wallis.

A superb team from Clausen Kran AG with technical assistance from Liebherr in advance and perfect crawler crane technology made the extremely difficult approach possible.
Geri Clausen is completely happy with his Liebherr telescopic crawler crane. He commented, "We have lots of sites where this highly manoeuvrable crane is simply perfect."

Bauer & the Hong Kong-Macao-Zuhai Bridge

Bauer & the Hong Kong-Macao-Zuhai Bridge

The special foundation subsidiary BAUER Hong Kong Ltd. is involved in the construction of the world’s longest bridge over water, currently under construction in the Pearl Delta.

The 50 kilometer link connecting Hong Kong, Macao and Zhuhai forms the southern ring closure of a gigantic infrastructure project.

The bridge consists of a multitude of individual structures, such as cable-stayed bridges and a 6.7 kilometer long tunnel, allowing uninterrupted passage of large vessels. Artificial islands form the end points and landing points. All structures are connected by a viaduct.

The joint venture Dragages-China Harbour-VSL commissioned Bauer Hong Kong with the installation of offshore bored piles for the Hong Kong Link Road (HKLR) – a 10 kilometer long section from the border between China and Hong Kong to the Hong Kong international airport.
Piles with 2,300 and 2,500 millimeters in diameter are up to 115 meters long and will be installed in rock at depth of 2 to 5 meters.

All the work on this project, to be undertaken by Bauer Hong Kong, must be performed from the water. Five BG 40 rotary drilling rigs will be used – four of them are custom-built, with longer masts and larger main winches.

The rigs were transported by ships to the steel platforms, each accommodating only one machine.

In support are pontoons for four bentonite plants and for 300-tons heavy cycle cranes and accessories. Over 100 drilling tools were assembled at the construction site.
