Section 1: General Information
INTRODUCTION
This manual provides installation instructions for the Fairbanks Trident Precast
Concrete Deck Truck Scale.
For complete Trident scale installation, use:
• Methods and Procedures FF-2267 / 101732 (Appendix I)
• The certified prints/setting plans supplied with the scale
• This installation manual, 51255
The concrete foundation work must be performed according to the certified prints
issued for the specific customer and order number. (The name and order number
for the particular customer will be on the prints.)
NOTE:
shipping damage with the carrier.
It is the owner's responsibility to document, notify, and follow-up regarding
DESCRIPTION
The factory poured truck scales are available in various lengths and widths. The
scale is made up of modules of 10', 15', 20' or 23'4" in length. All modules are
assembled and welded at the factory. The concrete deck is mixed, poured, placed,
finished, and cured at the factory.
The scale should be located so that vehicles can approach and exit the scale as easily
as possible. The platform should be visible from the instrument location. Drainage of
surface water must be such that water does not collect under the scale. Smooth and
level approaches are required at each end of the platform to reduce loading shock
and facilitate testing of the scale. Approaches must conform to the requirements of
the law in the state in which the scale is being installed. In the absence of such laws
the approaches must conform to paragraph UR.2.6 National Institute of Standards
and Technology Handbook 44, which states that the first 10 feet must be level and
on the same plane as the scale platform.
NOTE:
Specifications and sizes are shown in
Appendix II
.
