NBT30H-2 SERVICE MANUAL CRANE INSTALLATION
TRUCK PREPARATION
Plan the installation of the crane location for:
• the front axle weight.
• the rear axle weight.
• the boom overhang.
Check the final weight to verify that final truck weight with
crane, reinforcement, counterweight and options such as jib,
etc. complies with the appropriate laws.
Welding Precautions
Sensitive truck computer and crane RCL system
components can be damaged by welding on the truck or
crane. The following precautions must be taken:
• Disconnect both positive and negative battery cables.
• Attach welding ground lead as close as possible to area
to be welded.
Positioning the Crane On the Truck
The final user of the crane must be familiar with state axle
and length laws in force at the time the crane is mounted on
the truck. Following are items which must be considered:
• Overall Length - Most states have a maximum straight
truck length limit of 12.19 m (40 feet). Using a truck that
has too long of a wheelbase may exceed this limit.
• Axle Weights - All states allow 9,072 kg (20,000 lb)
single axle weight and 15,422 kg (34,000 lb) tandem
axle weights on primary roads. However, some states
restrict the axle weight to less on secondary roads or at
certain times throughout the year. Be aware of your
state’s axle laws for weight restrictions.
