The term "Ball Bank Indicator"
refers to an inclinometer (or Accelerometer used as an inclinometer) that is used for the specific purpose of
determining safe (uniform
for horizontal curves.
measures the overturning force (side friction), measured in degrees, on
a vehicle negotiating a horizontal curve -
whether it is
an isolated curve, multiple "S" curve, or a ramp to/from a freeway.
It is a standard operating instrument used by Federal and State
Departments of Transportation Nationwide along with other advisory
transportation agencies including consulting civil engineering
With Federal and State MUTCD
recommending a variety of angles for setting safe curve speed, we've
combined several options, and more into the industry leading digital
RDS7-BB - making it easy to adjust for your specific safe curve speed
The original Ball Bank
Indicator - 1023W1 (shown above) - has been the industry
standard for ball banking for decades - used throughout the USA by DOT, highway and traffic engineers.
Precision tube manufactured to MIL specifications, ±20º range, accurate 1º
increments. Simple to use, it is a fast precise visual indicator.
The RDS7-BB-09 digital ball banking unit
features an audible alert, an LCD displaying angle to 0.01º, RS232 output
(instant readouts right to your laptop), and programmable trip angles for
MUTCD compliance. Being the most versatile and
easy to use ball banking
package, it does not require a second operator to record the angle,
the audible alarm alerts the driver allowing him to keep his eyes on the
road - more cost effective and safer to operate.
