Hunter's B400T
utilizes PC-based technology to measure braking forces for every brake
on a vehicle: tandem-axle tractors; tractors and semi-trailers; buses;
2-axle vehicles, including passenger cars and light trucks.
Drive On and
Stop
Drive the vehicle
onto plates and apply the brakes. Precision load cells automatically
measure braking forces and dynamic weight. As each axle is tested,
results are displayed on the color monitor. Results are automatically
stored and can be printed out at the end of the test... all in 60
seconds or less!
Measures
Weight Shift During Braking
The B400T takes into
account the rear-to-front weight shift that occurs during braking,
resulting in a more accurate evaluation of brake system condition and
emergency stopping ability than roller type testers
Brake Balance
Results
Segments
inside each "wheel" indicate braking force as a percent of weight; the
more segments, the higher brake strength. For an "ideal" vehicle, all
segments would be the same length. It's easy to see which brakes are
doing their job. Segments are coded green for pass, red for fail.
Arrows on each axle indicate side-to-side balance, with the green area
indicating pull. Arrows below the wheels show adhesion utilization, a
measure of braking effectiveness, color-coded for pass or fail.
Service Brake
Results
This
display provides raw brake force data. Curves plot braking force and
dynamic weight. Those at top are for the steer axle,
those at bottom are for the drive axle or tandem.
Color-coded bar graphs report the results. Green
means the vehicle passes, red indicates a problem
Static Weight
Results
Static
weighing is performed automatically as soon as the vehicle comes to
rest. The display shows static weight for each wheel, total for each
axle and total for vehicle, along with GAWR and GVWR. If an axle is
overweight, the accompanying arrow will turn red. All axle weight limits
are user programmable to accommodate different vehicle platforms
Conclusions
"Plain
English" description of vehicle results are color-coded and may be
printed. Green "Passed" is used for all tests that are OK. Red or yellow
coded messages are more in-depth and indicate a problem |
