S6.1.10.2 The center of gravity peak of the ballast to the stacked control truck will be less than twenty four ins above the top of the tractor’s 5th wheel.
S6.1.10.3 The brand new handle trailer enjoys one shaft which have an excellent GAWR regarding 18,one hundred thousand weight and you can a range, mentioned on the transverse centerline of your own shaft on centerline of kingpin, off 258 ±six inches.
S6.step one.ten.4 The latest control trailer are loaded so that its axle was piled at the cuatro,500 pounds in addition to tractor are loaded in order to the GVWR, piled above the kingpin just, on tractor’s 5th controls modified so that the stream towards the for each shaft measured from the tire-soil program is actually very almost proportional towards the axles’ particular GAWRs, as opposed to exceeding the new GAWR of the tractor’s shaft otherwise axles otherwise handle trailer’s axle.
S6.1.11 Special push standards. A motor vehicle armed with an enthusiastic interlocking axle system otherwise a front wheel push program that is interested and you can disengaged because of the driver try checked on program disengaged.
The following thermocouple might be hung from the a depth out of
S6.1.twelve Liftable axles. A car or truck having an excellent liftable axle was looked at on GVWR which have this new liftable axle down as well as unloaded auto pounds toward liftable axle right up.
Into the conditions regarding S5.step three.step three.step one and you may S5.step three.4.step 1, pressure from the trailer take to rig reservoir is first put in the 100 psi to have actuation evaluating and 95 psi to have launch evaluation.
S6.step one.fourteen When you look at the testing the fresh crisis braking system away from pulling auto less than S5.seven.3(a), the fresh hose pipe(s) are ventilated on environment at any time for around step one second and never more one minute before the crisis prevent initiate, as automobile are swinging during the rate from which this new end is going to be generated and you may people manual handle towards the pulling car safeguards experience from the standing to country video chat provide heavens and brake manage signals for the auto getting towed. Zero braking system software program is created from the amount of time the latest range(s) was ventilated till the emergency avoid initiate no manual process of vehicle parking brake system or pulling vehicles protection program happen since the new range(s) is ventilated up until the avoid is done.
The brand new braking system climate is counted from the plug-style of thermocouples hung on the estimate heart of your up against size and width really heavily stacked shoe otherwise disc mat, that each brake, because the revealed within the Contour 2
S6.1.fifteen Initial brake heat. Except if or even specified, the initial brake weather is no less than 150 °F rather than over 200 °F.
The second thermocouple is hung at the beginning of the fresh shot series in case your liner don is anticipated to-arrive a area causing the basic thermocouple to get hold of the newest rubbing surface of a drum or rotor. 080 inch and discover contained in this step one inches circumferentially of thermocouple installed in the .040 inches breadth. To possess center grooved footwear or shields, thermocouples is hung in a single-8th of an inches to just one-quarter out of an inch of one’s groove and as next to the heart as possible.
S6.1.17 Gang of compliance options.

S6.2.step 1 New dynamometer inertia for every single controls is equivalent to new stream on wheel toward shaft stacked so you’re able to the GAWR. Getting a motor vehicle with even more GAWRs given to have process in the faster performance, the latest GAWR used is the fact specified getting a speed off 50 mph, or, during the accessibility to the company, one speed greater than fifty miles per hour.
