2. Ensure sheave mast assembly, if so equipped, is
properly stowed.
3. If equipped, remove and stow the anemometer
assembly. For more information, see “Wind Speed
Indicator (Optional)” on page 3-36.
4. Retract and place the boom in boom rest.
5. Engage the swing brake.
6. Engage the house lock.
7. Lower the cab tilt completely down.
8. Secure the hook block/downhaul weight and A2B
weight:
• Either the hook block may be reeved over the main
boom nose or the downhaul weight may be reeved over
the main boom nose or auxiliary boom nose. The other
must be removed and stowed securely before traveling.
If the hook block or downhaul weight remains reeved on
the boom, it must be secured at the tie down on the
carrier provided for that purpose.
- Slowly hoist up until there is a slight tension on the
hoist rope. It may be necessary to override the A2B
function to tension the rope.
- The A2B weight needs to be resting on the wedge
socket so that there is slack in the anti-two-block-
chain.
NOTE: There needs to be enough slack in the A2B chain
so that the A2B switch does not switch between
open and close positions during travel.
If the chain is too tight, road bounce causes the
A2B switch to open and close numerous times and
this can damage the switch.
9. Ensure the center front stabilizer is fully retracted, if
equipped.
10. Ensure the outrigger beams and jacks are fully
retracted.
11. Engage the mechanical travel lock at each outrigger
beam.
12. Remove the jack pads and place on the stowage
brackets.
13. Engage the mechanical travel lock at each outrigger
beam.
14. Turn off the ignition and all other switches in the crane
cab.
15. Close and/or secure all windows and doors.
16. Exit the cab, lock the door, and stow the access ladder.
17. Secure any loads or lifting devices on truck bed or body.
18. Ensure tires are properly inflated.
19. Disengage the Power Take Off (PTO) and start truck
from the truck cab.
20. Release the park brake before moving truck.
WARNING
Do not travel with mast assembly extended to prevent
damage to equipment.
Failure to comply with these instructions may cause death
or serious injury.
CAUTION
Outrigger beams must be pinned for travel.
If not pinned, outrigger beams may drift out during travel.
