TYPES OF UNDERCARRIAGES

WITH PARALLEL SLIDING ARMS

In this track variation system, as in the previous type of undercarriages, the movement made by the boxes is a simple translation.


H-SHAPED CARRIAGE

As a difference to the variable gauge undercarriages with parallel or telescopic sliding arms, the H-shaped undercarriages are perfectly symmetrical.


WITH TELESCOPIC SLIDING ARMS

This type of expandable undercarriages allows for a track variability by means of a simple translation of the boxes.


PANTOGRAPH CARRIAGE

This particular system for track changing is composed of two different articulated systems: a crank and slotted link and an articulated quadrilateral.


FIXED UNDERCARRIAGE

The fixed-track undercarriages are used mainly for CRUSHERS, DIGGERS, SMALL PERFORATORS and in all SPECIAL APPLICATIONS where a catenary movement is required.
