The 3-rail lift picks up the switch section on three points which places less strain on the material.
The forces are distributed on the 3-rail lift so that the impact on the sleepers and attachment materials is also reduced.

WSM 08-275 3S

Three points, one result

For a continuous high level of quality when constructing switches, the high-performance switch tamping-alignment machine WSM 08-275 3S applies force on three points. To be precise, it has a 3-rail lift device. The switch section is therefore lifted at three points, and not as usual, at just two points.

Due to the fact that the lifting forces are distributed across the entire switch construction, the forces exerted onto the attachment materials and sleepers are reduced. This protects the material of the entire switch and track system.

High performance with absolute precision

The benefits of the high-performance switch tamping-alignment machine WSM 08-275 3S lie in the combination of the levelling system that also controls the lifting of the branched third line section during the 3-rail lift process, and the integrated automatic adjustment system. This specifically controls the track geometry to achieve the required end result.

The benefits at a glance

  • Combined lifting-alignment aggregate
  • Proportional levelling system
  • Einsehnen-3 & 4-point alignment system with laser control
  • Automatic adjustment for specific track geometry
  • 6-channel Servorgor writer
  • Manages minimum track radii of 150 metres

Tamping below the switches needs to be as thorough as under the rest of the track system, however it need to be worked with more weight due to its extremely individual overall construction. The WSM 08-275 3S can help here.

The machine can use the 3-rail lift that can lift the switches to the optimum even on minimum track radii of 150 metres allowing it to master even the most difficult of track and switch situations.
