| Resumen del asunto | Los criterios de inactividad identifican una o más bolsas de aire desinfladas como una condición de "inactividad". Esto se encuentra en la Parte 2, Sección 10, Subsección B8. El problema que ha surgido en Alberta es que las bolsas de aire del mercado de repuestos se han vuelto muy populares. Estas bolsas de aire (ver la imagen adjunta) son completamente secundarias a la suspensión de ballestas original del camión. |
| Justificación o necesidad | Creo que es necesario modificar los criterios para declarar un camión fuera de servicio para abordar este problema. Se está declarando a los camiones fuera de servicio por tener desinflados los airbags auxiliares secundarios, cuando estos no representan un riesgo para la seguridad de los usuarios de la carretera ni dañan el vehículo durante el proceso de desinflado. |
| Solicitud de acción | Si se acuerda, modificar los Criterios de Fuera de Servicio para agregar una nota en la Parte II, Punto 10.(8).a para identificar que la suspensión de bolsas de aire secundarias/de posventa desinfladas en una suspensión primaria de ballestas/muelles helicoidales no da como resultado una Condición de Fuera de Servicio. |
| Medidas adoptadas por el comité | These air bags are completely secondary to the trucks factory leaf spring suspension. In some cases, the air bags are not used when the vehicle is in operation due to the load and they are not required. The current OOS criteria which states that a deflated air bag is OOS is resulting in these vehicles being placed OOS unnecessarily. The committee agreed that factory air bags and secondary air bags need to be treated differently. Further discussion determined that it would be necessary to add an Ops Policy 15 section to explain the difference between secondary air bags and OEM air bags due to the situations with current suspension that have both springs and air bags that are OEM primary suspension. It was further discussed most of these types of systems are found on smaller hydraulic braked vehicles (aka pickups) but can be found on larger trucks too. These air bag systems are added to improve handling and ride but do not increase the load carrying capacity of the vehicle. There was a concern brought up of how to get roadside officers to decide between primary and secondary air bags. It was indicated they used to be really popular to make the ride smoother. Hedrickson indicated that they sell a steer axle with an air bag and spring, and both are required. We need to ensure they officers don’t consider that to be secondary. It was further clarified that in no way are these air bags added on to increase the GVWR of the axle, they have no bearing on how much the axle can carry. They are just to make a better ride. The Vehicle Committee voted unanimously with one abstention to add language to the OOS criteria to reflect the following condition in the air suspension section of the criteria: 10. Suspension b. Spring Assembly (8) Air Suspension (a) Deflated air suspension (one or more deflated air spring/bag). NOTE: Deflated aftermarket/secondary air bag suspension in addition to a primary leaf/coil spring suspension does not result in an out of service condition. It was also discussed that guidance should go into the Operational Policy that these deflated bags are not a violation either. The Vehicle Committee vote was unanimous to add language to Operational Policy 15 to provide as guidance for officers as to the difference between a required air bag and a secondary/aftermarket air bag to read as follows: Suspension OOS Frequently Asked Questions 10.a.(4) What is the difference between a primary and aftermarket/secondary air bag suspension? Answer: The primary air bag suspension system is maintained in accordance with original manufacturer specifications whereas a secondary air bag suspension system is in addition to the original manufacturer spring or coil suspension. PICTURES INSERTED NOTE: Deflated aftermarket/secondary air bag suspension in addition to a primary leaf/coil spring suspension does not result in a violation. |
