The versatile one
At more than 140 metres long, almost 5 metres high and weighing about 560 tonnes, the track construction machine RPMW 2002-2 is one of the largest in the world. Due to its amazing output and the comprehensive performance range, it is an extremely important part of the Wiebe Group’s machine pool.
The recycling formation level improvement machine can perform a number of track construction tasks, with an overall motor output of in excess of 2400 kilowatts. This force is fully utilised in total reconstruction projects in which the RPMW 2002-2 carries out several work steps simultaneously: The soiled track bed is removed, the removed track bed material is treated, the ballast is recycled and the subgrade level is renewed.

The centrepiece of the work comprises the two excavation chains. They ensure that the ballast and soil can be removed and processed separately to prevent the two materials coming mixed. The RPMW 2002-2 also has a high-pressure washing system to treat the ballast and remove any residues and contamination. The track bed is first removed to a depth of 350 millimetres. It is even possible to renew the subgrade level up to a depth of 500.

The increase in rail traffic has lead to a steady increase in the demands made of track systems. Fortunately, the RPMW 2002-2 makes it very easy for us to keep pace with these developments.
In the case of comprehensive track construction and modernisation projects it is almost unimaginable today to use different machines for the individual work steps. For this reason, we fall back on the RPMW 2002-2 that picks up all the old material which is then processed and used to create a new formation level protective layer and a new ballast bed. A high-performance complete package.
14 sleepers a minute whilst also creating an installation formation level – the fast construction machine SUZW-500 stands out thanks to its performance.
The fast construction machine VFW 2001 can be used to build remove or modernise tracks either with or without prior or subsequent track bed cleaning.
Thanks to a laser-supported 3-rail lift, even split sleepers can be processed by this very versatile track and switch tamping machine.
