S6.step one.10.2 The midst of gravity peak of ballast with the piled manage trailer shall be lower than 24 inches over the the top of tractor’s fifth wheel.

S6.step one.ten.3 The new manage trailer possess an individual axle having an excellent GAWR away from 18,100000 lbs and you can a point, counted on the transverse centerline of one’s shaft towards the centerline of kingpin, out of 258 ±6 inches.

S6.1.10.4 The fresh manage truck try piled so its axle was loaded during the 4,500 weight additionally the tractor are stacked so you’re able to their GVWR, piled above the kingpin simply, for the tractor’s fifth wheel adjusted so that the stream for the for each and every shaft measured from the tire-ground user interface was very almost proportional toward axles’ particular GAWRs, without surpassing the GAWR of one’s tractor’s shaft otherwise axles or control trailer’s axle.

S6.step one.eleven Special drive requirements. A vehicle equipped with a keen interlacing axle system or a side wheel drive program that’s involved and you will disengaged because of the driver try examined on the program disengaged.

Next thermocouple might be installed on a degree out-of

S6.1.several Liftable axles. A motor vehicle having a great liftable shaft is checked-out within GVWR with this new liftable axle down at unloaded vehicle weight towards liftable axle upwards.

To your requirements out-of S5.step 3.step 3.1 and S5.3.cuatro.1, the pressure about trailer sample rig reservoir try first set during the one hundred psi getting actuation testing and you will 95 psi to own discharge examination.

S6.step 1.fourteen From inside the evaluation the brand new disaster brake of towing vehicle significantly less than S5.eight.3(a), the fresh line(s) is actually vented on ambiance any moment for around step one next and never more about a minute till the emergency stop begins, since the vehicles is actually moving at the speed where brand new prevent is usually to be made and you may people tips guide control with the towing vehicle safety experience throughout the status to offer air and braking system manage signals on the vehicles becoming towed. Zero brake application is produced from committed the latest line(s) is actually vented until the emergency prevent begins with no manual process of the vehicle parking brakes otherwise towing vehicle security program takes place from the time this new range(s) is actually ventilated until the prevent is done.

The newest braking system temperature is mentioned by connect-kind of thermocouples hung on the calculate cardio of up against duration and you will width of the most greatly stacked shoe otherwise disc mat, that for every brake, as the found inside Contour dos

S6.1.15 Initially brake heat. Until if you don’t given, the original braking system temperature is not less than 150 °F rather than over 2 hundred °F.

One minute thermocouple can be hung early in the newest attempt series in the event the liner don is expected to reach a area evoking the first thermocouple to get hold of the brand new friction skin of an instrument or rotor. 080 inch and you may found contained in this step 1 inch circumferentially of one’s thermocouple installed during the .040 inches breadth. To own heart grooved boots or shields, thermocouples was hung within one-eighth from an inches to at least one-quarter away from an inch of groove so when next to one’s heart that you could.

S6.step 1.17 Band of conformity choice. Where brand name options are given, the producer should get the solution once it certifies the auto and can even perhaps not afterwards see a different option to have the auto. For each and every company should, up on consult regarding the Federal Path Travelers Coverage Administration , offer details about hence of one’s conformity choice it offers chosen for a certain car or build/design.

S6.dos.step one The fresh dynamometer inertia for each and every wheel matches brand new load towards wheel toward axle stacked to the GAWR. Having an automobile that have a lot more GAWRs given for process on quicker performance, the GAWR put would be the fact given to own a rate out-of 50 mph, or, on option of producer, any rate greater than fifty miles per hour.
