Hitachi excavators tackle underground job

We have seen a massive rise in readers from Finland following the publication of Olli Paivio's excellent article on the Digger blog in the latest edition of Finnish magazine Koneporssi.

One such reader is Hannu Rinne-Laturi who works for the family business Rinne-Laturi, a company which was established in 1962 and has a very good reputation in and around the Finnish capital of Helsinki.

Hannu has sent in some impressive photos of a major job the company were involved in during 2007-2008 in which their Hitachi excavators were involved.

The job involved the excavation and construction of a 600 space underground car park below one of Helsinki's most prestigous stores Stockmans.

The job also involved the construction of a service tunnel and in some places the dig was down to a depth of 33 metres. In this photo Hannu's ZX225 US is sat on the bridge which goes over the service tunnel, in this instance Hannu's machine is equipped with a grab which they used to move the sheet piles around.

As well as operating the 225US model Hannu was also involved in operating the company's ZX18 mini excavator which can be seen here being crane lifted in to the job by the ZX225US.

The Hitachi ZX225US machines with their short radius compact design were ideal for this type of work and when coupled with the tiltrotator attachment which is so common in Scandanavian countries makes the machine a great all rounder when working in confined spaces.

This last shot shows once again how useful the compact radius machines are in these kind of conditions.

Thanks to Hannu for sharing these outstanding photos with us here at the Digger blog.
