SafetyWatch Technologies, Inc. (SWTI) has spent the past almost 20 years developing a durrable and accurate brake reporting platform for heavy trucks. And now, for the first time, you can know what condition your trailer brakes are running at too. In other words, your trailers can now pull their own weight in the overall equation of stopping power. And know that ABS doesn’t have anything to do with stopping power. However, if the tractor-trailer brakes aren’t in adjustment, none of the technologies forming the pyramid that sits on top of each brake will work to their potential. These technologies include: Anti-lock braking system (ABS), Automatic tracking control (ATC), electronic stability control (ESC), and at the top are various versions of collision avoidance systems (CAV).

SWTI introduces its fully developed and patented a heavy truck brake reporting system. SWTI’s system can read brake push-rod data from a tractor and trailer or trailer only. The system consists of sensors at each brake and electronic control units connected by signature [patented] software that moves in real time. The system shows both the pushrod travel of each brake, as well as the timing of each brake. You now know if the truck’s air valves are firing in sequence and that the truck/trailer pushrod travel are within DOT allowed specifications.

  • Show whether pushrod travel is within USDOT specifications.
  • Detect air leaks or valve problems via pushrod travel information.
  • Show whether the timing of the brakes is balanced, i.e. left and right, as well as the timing of the crack pressures which should activate from the back to the front.
  • Notifies operator if one or more brakes are out of service and catch the problem brake before the mandatory 20% of the brakes become out of service which puts the entire tractor-trailer out of service on the spot if the operator should get pulled over.

Comments made by DOT/CVSA Inspectors; the system is:

  • Passive, does not interact with the brake.
  • Is simple and can be easily checked for accuracy.
  • If one sensor fails, this event doesn’t affect the readings of the other system sensors.
  • Its operation requires only one person to operate without leaving the cab of the truck.
  • Data is retrieved by simply depressing the brake pedal. The data is then captured and moved to a screen in the cab. Or, the system can be integrated with your on-board computers.
  • Currently, it takes two mechanics to check the brakes. One mechanic underneath the truck or trailer sliding from brake to brake hand-measuring the pushrod travel. If the tractor-trailer has 5 axles, the operator must check ten brakes. During this time, the second person is sitting in the cab and depressing the brake pedal for each individual brake test. Therefore, if it takes two minutes to check each brake (there are ten brakes on a standard five axle semi-truck) and you had two technicians each working 20 minutes, there would be a total of 40 minutes of work time versus one technician that can do the test in less than five minutes.

Additional Savings:

  • By reducing time required for physical brake checks will mechanics increased time to conduct expanded truck maintenance.
  • Reduce brake part throw-aways.
  • Reduce down-time for a truck and its driver.
  • Reduce penalties from USDOT or State DOT for brakes not in compliance.
  • Save payloads.
  • Prevent environmental spills from payloads and on-board fuel.
  • Save lives.
  • Save court awarded damages.
