Extended Travel
Depending upon the tire manufacturer, the higher inflation
pressures normally specified for lifting on rubber are not
recommended for site to site transfer over extended
distances. The higher static/creep 8 km/h (5 mph) inflation
pressures may remain in the tire while operating the crane
on site within a distance of less than 6.4 km (4 mi).
CAUTION
Tire Damage Hazard!
For extended travel, check cold tire pressure before start.
(Refer to tire inflation chart in Load Chart Book.) After
every 1 hour of travel time, regardless of ambient
temperature, stop and allow tires to cool for at least
30 minutes. At destination, tires must be allowed to cool
to ambient temperature before crane lifting on rubber.
