With the Unimat 08-475/4S, Plasser & Theurer has succeeded in perfectioning switch maintenance. Besides the synchronous three-rail lift, this machine can tamp the fourth rail at the same time. To produce the sleeper bearing surface necessary for the precision of the switch geometry, the outer tamping units are slewed out so that the deflecting line of the switch is also tamped. The entire switch system is treated in the technologically correct way and fixed immediately in the correct position by full tamping.

The Unimat 08-475/4S machines are working in many countries with great success and prove over and again how the cost-efficient, precise and careful maintenance of heavy switches can be performed.
