Coordinate measuring machines of the gantry type are used for measurements of very large parts in system manufacturing and heavy machine construction, but also in the car body and mold making sectors of the automotive industry, for example when measuring wind tunnel models.

For reasons of stability, the measuring machines of the gantry type are built very solidly. Owing to their large size, geometric changes caused by non-uniform temperature distribution have a particularly large effect.
