S6.step 1.10.dos The center of gravity top of the ballast into loaded manage truck will be below 24 ins above the the top of tractor’s fifth wheel.

S6.step one.ten.3 The brand new handle trailer keeps a single shaft which have an effective GAWR regarding 18,one hundred thousand pounds and a range, mentioned from the transverse centerline of one’s shaft on the centerline of your own kingpin, out of 258 ±six in.

S6.step one.ten.cuatro The fresh control trailer is actually piled to ensure that its shaft is actually loaded at cuatro,five hundred weight while the tractor is actually stacked to help you their GVWR, loaded over the kingpin simply, on the tractor’s 5th wheel modified so the stream for the each shaft counted on tire-floor screen try very almost proportional into the axles’ particular GAWRs, in the place of exceeding the fresh new GAWR of tractor’s shaft otherwise axles otherwise handle trailer’s axle.

S6.1.11 Special drive requirements. A car married couples looking for third equipped with an enthusiastic interlocking axle program or a front controls drive system that is involved and you will disengaged by rider is actually examined for the program disengaged.

The second thermocouple would be hung from the a level from

S6.1.12 Liftable axles. A car or truck which have a beneficial liftable axle was examined within GVWR that have the new liftable shaft off as well as unloaded automobile lbs on the liftable axle upwards.

To the requirements of S5.3.step 3.step one and you will S5.step 3.4.step one, the pressure regarding the truck shot rig tank try very first put from the 100 psi getting actuation assessment and you can 95 psi to own discharge testing.

S6.step one.fourteen Inside comparison the brand new crisis brake regarding towing automobile below S5.7.3(a), new hose(s) try vented into the conditions at any time for around step 1 second rather than over one-minute before disaster avoid begins, since auto was swinging on speed of which new avoid will be produced and you can one guide manage for the towing automobile security system is regarding the status to provide sky and braking system manage signals for the vehicles getting towed. Zero braking system software is made from enough time the latest line(s) are vented up until the disaster avoid begins without guidelines process of your vehicle parking brakes otherwise pulling automobile defense system happens ever since the range(s) is ventilated through to the avoid is accomplished.

The braking system temperature is mentioned by the connect-style of thermocouples hung throughout the estimate heart of your own facing size and you can thickness of the most greatly piled shoe or disk mat, you to definitely for each braking system, since the found for the Figure dos

S6.1.15 Very first braking system temperature. Unless of course if not specified, the first braking system temperature is not less than 150 °F and never more than 200 °F.

A moment thermocouple could be strung early in brand new decide to try sequence in the event your lining don is anticipated to arrive a beneficial area resulting in the earliest thermocouple to make contact with the brand new rubbing body off a guitar or rotor. 080 inch and found contained in this step one inch circumferentially of your own thermocouple installed during the .040 inches depth. Getting heart grooved shoes or shields, thermocouples try hung within one-8th of an inch to one-quarter off an inches of groove and also as near to the center that one may.

S6.2.step 1 The fresh dynamometer inertia for every wheel is equivalent to this new weight with the controls on the shaft loaded so you’re able to their GAWR. Getting an auto having extra GAWRs given for procedure within shorter increase, the brand new GAWR made use of is that specified having a rate off 50 mph, or, from the option of the maker, people rates greater than fifty mph.
