Colas Sud Ouest invests in Hitachi versatility

Sand and gravel buried beneath a lake would be out of reach for many excavators - but the Hitachi super long front ZX350LC-3 extracts the materials with ease. In the famous French wine-growing region of Bordeaux, the Colas Sud Ouest-owned company, Sarrazy T.P., is using the versatle excavator on two diferent sites.

In Naujac-sur-Mer, the excavator digs to a depth of five metres, removing 70,000 tonnes of raw materials from beneath the man-made lake each year. At a second location in Queyrac - which processes 30,000 tonnes of aggregate annually - it excavates to a depth of nine metres.

Sarrazy T.P., which was taken over by the Colas Group in 1992, took delivery of the Zaxis medium excavator in 2009, from local authorised dealer, DB Equipment. “We needed a machine that could dig deep into the water,” says Christan Bell, the Area Manager for Sarrazy T.P. “It was also bought to work at the two sites, so we needed a versatle and reliable soluton. The super long front ZX350LC-3 has already proved its worth in these respects.”

The Naujac sur Mer site - which also recycles 15,000 tonnes of concrete per year - was originally a pine forest, but it was wiped out by a huge storm in 1989. The lake there has been created by materials being excavated and lef to dry around the side of the pit. It has become a haven for wildlife, atractng herons and gulls, enhancing the biodiversity of the environment.

The super-long-front’s 18 m front attachment is ideal for working under the water and the machine also loads Sarrazy’s feet of artculated dump trucks. However, the company has recently ordered a Hitachi ZW220 wheel loader, which will take over the later task.

Christan is confdent the wheel loader will be a wise investment. “We decided to buy the ZW220 because of the success of the ZX350LC-3,” he says. “We are delighted with the support provided by DB Equipment and have established an excellent working relatonship together.”

Up to 64 Bauer Drilling Rigs at work for the Winter Olympics

In February 2014, the Russian Black Sea resort of Sochi is to host the Winter Olympic Games. Prior to staging the Olympics, an extensive programme of constructon works has to be completed. In additon to the constructon of new sports venues and numerous hotel complexes, the constructon of new road and railway links has over the past two years turned the city into one large constructon site.

New sports facilities and bridges need solid foundations and specialist foundaton engineering. As a result, Bauer Technologie, the Russian subsidiary of BAUER Spezialtiefbau GmbH, is carrying out various projects in Sochi. Particularly notable, however, is the large number of Bauer rotary drilling rigs that can be seen at the various constructon sites around the city. At tmes, up to 64 heavy-duty Bauer drilling rigs have been in operation concurrently, primarily BG 28s, but also several rigs of the BG 36 series. Five of these rigs have been operated by Bauer Technologie, whilst the other 59 machines were owned by a whole range of Russian constructon companies who had

come to Sochi from many different regions. The difficult local geology, comprising rather heavy soils, makes serious demands on specialist foundaton engineering technologies. Piles had to be drilled to depths of 30 m and even 40 m. Constructon for the Winter Olympics includes eleven new sports facilites which are to be completed by the end of 2012. Along the coast of the Imeretnskaya Bay, the Olympic Park is under constructon featuring fve stadiums for
