40T series reference
Beam span and overall length are different.
Equipment mass forms part of the crane-capacity assessment alongside the load and rigging.

Reference: supplied VLN 2.0 manual, p16. Other product revisions differ. Use the current data sheet for final equipment selection.
Capacity follows the rigging arrangement.
| Beam span | 45° upper angle | 60° upper angle | 70° upper angle |
|---|---|---|---|
| 7 ft | 29 t | 40 t | 40 t |
| 11 ft | 25 t | 40 t | 40 t |
| 15 ft | 21 t | 40 t | 40 t |
| 19 ft | 17 t | 40 t | 40 t |
| 20 ft | 16 t | 40 t | 40 t |
Example 40T CA arrangement from supplied Caldwell/Vita 072925 load tables, maximum outward lower sling angle 20°. Use the complete applicable load table for the actual lift.
