|
|
| Does anyone know the exact law regarding switches for lift axles? I was told by a Georgia dot officer that since the switch was in the cab, the axle doesnt count. the federal motor carrier web site says that if the lift axle is one of the tandems, the switch must be outside, my axle is a 3rd axle so does not fall into this category. I have emailed fmcsa and ask the law, but neither one will bother to answer me. |

Don't know what Georgia DOT was talking about-Of course it counts
I'm assuming you meant tag axle on the Trailer? |

| yes, trailer has 3 axles... a fixed tandem axle and a lift axle, according to the dot man, lift axle doesnt count because switch is in the cab. he said the truck only counted as a tandem, I think the owner just paid the ticket, If it was my truck, we would be in court. |

The DOT man is correct. The State of Georgia does NOT recognize the tag axle is the controls are on the inside. When you picked up our new new T-800 a couple of months ago in TN, we asked about the switch and that's what they told us. It was confirmed a few miles down the road at the first set of scales in GA.
BTW, here's the pic of the new wrecker with the decals on it!

| MD is the same way i don't know if the switch to take it up and down has to be on the outside but i know the switch to adjust the air pressure for the axle has to be on the out side. |

| In Maryland the regulator for the down force on the lifting axle has to be on the outside but the switch can be on the inside. |

How are you suposed to turn corners with your lift axle down? if the switch is outside?
I always lift axle before turning. |

| if the lift axle is on the truck the tires turn with the truck. if it is on the trailer it stays in the same position as the rest of the trailer tires do. |

So you are saying that most trucks have a steering lift axle on the tractor?
Not lifting the axles to turn is really hard on the tires.
If's its a non steering axle.
Some lift axles around here are steerable too, but not all them yet. |

| I allways put up the lift axle on a turn its hard on the truck and you don't have no turn radius with it down. I would need 40 acers to make a turn if i didn't lift it up. That's on a tri axle straight truck am talking about not a trailer. |

| Here in Wisconsin and Michigan I believe the rule is that the switch can be inside but the regulator must be outside to keep us outlaws :D from cheating the scales. On the other hand, I haven't heard of anyone getting ticketed for the regulator being inside. It is normal that the new trucks have the regulator on the outside. |

| All our Tag axle switches are on the Inside and this Outside Tag axle switch is beyond my Comprehension. |

Quote: ?393.207 Suspension systems.
(a) Axles. No axle positioning part shall be cracked, broken, loose or missing. All axles must be in proper alignment.
(b) Adjustable axles. Adjustable axle assemblies shall not have locking pins missing or disengaged.
(c) Leaf springs. No leaf spring shall be cracked, broken, or missing nor shifted out of position.
(d) Coil springs. No coil spring shall be cracked or broken.
(e) Torsion bar. No torsion bar or torsion bar suspension shall be cracked or broken.
(f) Air Suspensions. The air pressure regulator valve shall not allow air into the suspension system until at least 55 psi is in the braking system. The vehicle shall be level (not tilting to the left or right). Air leakage shall not be greater than 3 psi in a 5 minute time period when the vehicle's air pressure gauge shows normal operating pressure.
(g) Air suspension exhaust controls. The air suspension exhaust controls must not have the capability to exhaust air from the suspension system of one axle of a two-axle air suspension trailer unless the controls are either located on the trailer, or the power unit and trailer combination are not capable of traveling at a speed greater than 10 miles per hour while the air is exhausted from the suspension system. This paragraph shall not be construed to prohibit-
(g)(1) Devices that could exhaust air from both axle systems simultaneously; or
(g)(2) Lift axles on multi-axle units.
The rule applies to air system exhaust not lift axles.
Be safe. |
