NTC55 OPERATOR MANUAL CONTROLS AND OPERATING PROCEDURES
National Crane Published 9-26-2018 Control # 646-02 3-23
1. Ensure the swingaway, if so equipped, is properly
stowed and secured or removed from crane.
2. Ensure sheave mast assembly, if so equipped, is
properly stowed.
3. Retract and place the boom in boom rest.
4. Engage the mechanical travel lock at each outrigger
beam.
5. Engage the swing brake.
6. Engage the swing lock.
7. Lower the cab tilt completely down.
8. Secure the hook block/headache ball and A2B weight:
• Either the hook block may be reeved over the main
boom nose or the headache ball 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 headache ball 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 cable. It may be necessary to override the A2B
function to tension the cable.
- 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 single front outrigger is fully retracted, if
equipped.
10. Ensure the outrigger beams and jacks are fully
retracted.
11. Remove the jack pads and place on the stowage
brackets.
12. Engage the mechanical travel lock at each outrigger
beam.
13. Turn off the ignition and all other switches in the crane
cab.
14. Close and/or secure all windows and doors.
15. Exit the cab, lock the door, and stow the access ladder.
16. Secure any loads or lifting devices on truck bed or body.
17. Ensure tires are properly inflated.
18. Disengage the Power Take Off (PTO) and start truck
from the truck cab.
19. Release the park brake before moving truck.
CAUTION
Machine Damage Hazard!
Do not travel with an empty hook in a position where it can
swing freely. Either remove the hook block and/or

secured to the tie down provided for that purpose.
Fully retract the outrigger jacks and properly store the
floats.
