Traditional Air Brake Training Systems
We have 2 generic displays shown. One display contains the traditional 3 air tank dual system and it is built with Bendix air brake valves and dryers. The antilock portion can be the Meritor/Wabco D or E version ABS or the Bendix EC-60 Premium System. Digital wheel speeds can be utilized on all displays. Motor/tooth wheel sensors work only with Meritor/Wabco systems. |

Bendix AD-IS Air Dryer System
Many of the new systems today eliminate the supply reservoir and utilize the unique combination of pressure protection valves found in the AD-IS air dryer. The combination of different opening pressures allows the reservoirs to charge independently of one another, and then work together as one large air supply to meet federal regulations. When system pressure drops to the preset closing of the protection valves, they close, separating the primary, secondary and accessory reservoirs. |

Transit Bus Displays
Transit bus displays are unique in design, as most fleets have specific needs and requirements. As a result, we generally build to OEM drawing or prints supplied by the customer. The photo above is unique as it incorporates the MGM E-Stroke electronic brake stroke indicator, along with antilock and traction control. |

We custom design school bus, cement mixer and all specialty systems. |
|
Custom design complete school rooms including cabinets. |

Portable Displays
The need to transport displays from one location to another is sometimes necessary. We can design a unit to fit most any need. |

Antilock Brake System
Our standard
antilock system is the Meritor WABCO 4S/4M (4 sensor/4
modulator) with a separate trailer system. It is
incorporated into the air system and fully functional.
Bendix antilock brake training is an option.
General
Operation:
Tooth wheels
are driven with 12-Volt DC motors (one at each axle).
Sensors, along with the tooth wheel, create an AC output
signal to the ECU. At the push of a button the motor
spins the tooth wheel to 60 MPH. Depressing the button a
second time brings the wheel speed down to 20 MPH in 1.5
seconds and gradually to a stop. This rapid
deceleration triggers a wheel lock-up situation and the
antilock system functions the same as tires skidding on
ice.
 A
second button triggers a traction control feature. Push
the button twice and the drive axle spins over 60 MPH
while the steer axle remains stopped. This sudden wheel
spin triggers the traction control and applies brakes to
the spinning wheel. The entire system works just like it
would on a vehicle.
Features:
- Engine Simulator provides input for the traction control feature.
- Electronic control panel mounted on the back of the display provides control of the tooth wheel motors at the touch of a button.
- All components, speed sensors, wiring, electronic control units, ATC valve and modulators are mounted and functional.
- Labels identify the wires by color code, location and pin connections at the ECU.
- AJ1587 diagnostics port provides the hook-up for laptop computer diagnostics or ProLink test equipment.
- Blink code switch provides the ability to test the system without computers. Lights for both the ATC and antilock functions are mounted on the face of the panels.
- Maintenance and training manuals, slide charts, and training videos are available.
