GENERAL
This section provides information for proper mounting and
initial check out of the crane. Improper mounting can result in
damage to the truck frame and drive train, the hydraulic
pump, and cause crane instability. The 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.
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 fuel and
personnel [at 90 kg (200 lb) each].
National Cranes must 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.
Any work done in mounting must be done in compliance with
these codes.
NOTE:
Verify that the number on the serial number plates
on the major components match the main serial
number located on the crane frame (Figure 9-1). If
the serial numbers do not match, contact the
factory before proceeding. Matching serial
numbers insure that accurate information is
recorded at the factory.
MINIMUM TRUCK REQUIREMENTS
The minimum truck requirements for mounting the NBT30H-
2 series cranes are as follows:
•
Axle Rating -
Axle ratings are determined by the axles,
tires, rims, springs, brakes, steering and frame strength
of the truck. If any one of these components is below the
