Full electronic modular scales
are more accurate and dependable in the long term
than mechanical scales, and
they have much lower maintenance costs.

The most popular electronic rail scale
products are the combination truck/
rail scale and the modular rail scale.
The combination scale is designed for
installation in a conventional deep pit
with the platform at grade level. The
scale can be installed for weighing both
rail and truck traffic, providing maximum flexibility. It is typically 60 to 75
feet (18 to 22 meters) in length and designed for a concrete deck. The combination scales have a nominal capacity
of 360,000 pounds (163,260 kg) and an
180,000-pound (81,630 kg) sectional
capacity.
Modular type rail scales have increased
in popularity during the last two decades,
primarily due to the lower costs of installation and foundation construction.

shallow pits.
Full electronic modular scales are
more accurate and dependable in the
long term than mechanical type scales,
and they have much lower maintenance
costs. These models are available in a
variety of platform lengths and widths
to handle a wide range of vehicles.
The flat top modular design can also
be customized to fit existing foundations, often saving thousands of dollars
in replacement costs of older models.
Options such as grain dumps, safety
guide rails, automated controls and
other accessories make this design the
popular choice.
