Automatic Impact Brake for TMAs
Applies Air Brakes during a TMA Impact
The Automatic Impact Brake System (AIB) is designed to be mounted
to a Truck Mounted Attenuator (TMA) for use during slow moving operations
such as spraying or striping. When a vehicle impacts the TMA, the
AIB System automatically applies air brakes, reducing the braking
time to stop the truck.
In The Event Of An Impact
An unmanned TMA shadow vehicle equipped with the AIB System would
automatically apply air brakes to reduce vehicle rollahead. When
the tape switch is activated, an air pulse is sent to the control
box that activates the system to lock the brakes on the TMA shadow
vehicle. The TMA shadow vehicle must be equipped with air brakes
in order to utilize the AIB System.
Description of System
The AIB System consists of an in cab control box, a solenoid valve,
a shuttle valve, two tape switches, and installation hardware. The
tape switches are mounted to the rear of the TMA such that an impacting
vehicle triggers the switch causing a solenoid valve to be energized
which in turn routes air pressure from the emergency brake line
to the rear brakes of the truck.
