Load Ratings
| Carriage Type | C0 Static Load (N) | C100 Dynamic Load (N) | M0Q Static Cross Moment (Nm) | M0L Static Long. Moment (Nm) | MQ Dynamic Cross Moment (Nm) | ML Dynamic Long. Moment (Nm) |
|---|---|---|---|---|---|---|
| A / C / F | 74,900 | 39,500 | 1,332 | 966 | 702 | 510 |
| B / D / G | 98,500 | 48,900 | 1,751 | 1,614 | 869 | 801 |
Load Rating Definitions
- C0 = Static load capacity - Maximum allowable load causing permanent deformation
- C100 = Dynamic load capacity - Load for 100km travel life
- M0Q / MQ = Cross moment - Rotation around travel axis
- M0L / ML = Longitudinal moment - Rotation around vertical axis
