812 Series, Expansion Unit, CU400A PVCPH 4M GA
To compensate for changes in length due to temperature for systems > 100 m or segments connected between two fixed points such as Pickup Guides on both ends of the segment, or in curves (natural fixed points), expansion elements are needed to absorb the change in length. The expansion element has two expansion points, each of which can absorb 25 mm of expansion. The expansion elements / expansion unit parts are, like the rails, designed as 4 m standard components.
