SELECTION OF THE WHEEL GROUP

✓ SELECTION (TRAVELLING MASS)

✓ CHECK THE MATCHING OF THE WHEEL WITH THE RAIL

✓ CHECK THE PERFORMANCE

SELECTION OF THE WHEEL GROUP: SELECTION DONE CONSIDERING THETRAVELLING MASS

TRAVELLING MASS = OWN STRUCTURE WEIGHT + LOAD TO BE TRAVELLED

EXAMPLE:

❑ THE CUSTOMER ALREADY SELECTED AN EXISTING RAIL: WE HAVE TO ADAPT ❑ WE CAN SUGGEST TO THE CUSTOMER THE MORE SUITABLE RAIL TO MEET OUR STANDARD TOO

SELECTION OF WHEEL GROUP DGT: CHECK IF MATCH

DONATI WHEEL GROUPS: CHECKING THE PERFORMANCE
