This particular track width variation system is made up by of two separate articulated assemblies: an oscillating glyph and a four-bar linkage The first provides movement, while the second guides the crawlers during the displacement.
The symmetry of the undercarriage, the reduced footprint of the system given the same extended track width, the increased strength of the undercarriage are the advantages that this track-width extension system offers compared to the other undercarriages; on the other hand, the pantograph system is more complex.
This makes the pantograph undercarriages particularly suitable for applications where great stability and a large supporting base are needed. Undercarriages with a pantograph track variation system are very often used in coupling with cranes or lifting systems.
