More than 7 000 holes needed to get the railguard in place
Helping hand. When the old steam railway in France is restored, more than 7000 holes have to be drilled to get a guard rail in place. Husqvarna's AD 10 automatic drilling system lets the drill work instead of the operator.
Husqvarna Construction’s drilling equipment is used when an old steam railway in the south of France is
being refurbished. The railway is situated in the department of Ardeche and connects the small towns of Tournon and Lamastre. On its way it passes through a breathtaking landscape with high bridges, viaducts and the river of Rhône below. Until the late 1960’s, the railway was used for goods transportation. Since then, it has been used as a tourist railway. Now it’s being renovated and will, among other things, be equipped with a railguard for increased security. The contractor is the French construction company Découpe Béton Armé, DBA. Due to the tight time plan, it’s necessary to work as efficiently as possibly in each phase. The French construction company Découpe Béton Armé has chosen drilling products from Husqvarna to drill the more than 7 000 holes needed to get the railguard in place; the drill stand DS 450, the drill motor DM 340 and the AD 10. The automatic drilling system AD 10, in conjunction with Husqvarna’s drill motors and drill stand, offers an automatic, efficient drilling system. No manual work is needed to move the drill along the drill stand. The drilling is done by mounting the Husqvarna drilling equipment on a thick steel plate, which is moved forward as the work goes along.
Saving time with automatic drilling

“We are very pleased with the automatic drilling system. It saves a lot of time for us”, says Jean-Paul Brivet, Manager of DBA.
“The operator can stand comfortably upright when using the AD 10, without having to keep turning. With a speed of up to 3.2 m/min in both directions, our drill system is the fastest product of its kind on the market”, says Pascal Quignon, Sales Manager, Husqvarna Construction.
The AD 10 has been developed with a clear user focus. It’s simple to mount and manoeuvre. With the aid of a regulator, the operator controls the speed, direction and power of the AD 10 and the drill motor it is mounted on. The unit senses when the drill head has gone through the material and then automatically stops both the power supply and the drilling. The AD 10 has a compact design and weighs only 3.6 kg.
The railway project is estimated to finish in 2012. After that the old steam trains can safely continue puffing.
