This installation section provides information for
mounting and initial check out of the crane. One of the most
important elements in good long lasting crane performance
is proper mounting. Improper mounting can cause
permanent damage to the truck, i.e. frame or transmission,
and the crane, i.e. pump or non-stability. Also Federal
Department of Transportation Laws relating to vehicle
manufacture and modification such as lights, brakes and
axle loads must be met as well as State vehicle laws relating
to weights and dimensional restrictions such as overall
length, overhang, etc. This section is organized by first
presenting detailed information relating to truck requirements
and mounting configurations followed by a step-by-step
installation procedure including PTO selection,
reinforcement, crane and stabilizer installation,
counterweighting, boom rests and stability testing. The final
manufacturer of the vehicle must certify that the axle ratings
have not been exceeded with all permanently attached
equipment including a full load of gas and men in the truck
cab.
National cranes should meet ASME/ANSI B30.5 (latest)
when completed as cranes and ASME/ANSI B30.23 (latest)
when completed as a personnel lifting system. These
standards require welds to meet AWS D14.3 or AWS D1.1
respectively. Therefore any work done in mounting should be
done in compliance with these codes.
Note: The following page lists the typical locations
for the Serial Number identification tags that are
fastened to the main components of the crane. Before
proceeding with the installation, verify that the number
on the serial number plates on the major components
match the main serial number which is found on the
crane frame. If the serial numbers do not match, contact
the factory before proceeding. Matching the serial
number plates insures that accurate warranty
information will be recorded at the factory and will aid in
dispensing service bulletins and other pertinent
information.
