Although not, any agricultural item truck, heavy hauler trailer, otherwise pulpwood truck will meet the requirements away from S5
7.dos Emergency brake system procedure. Brand new crisis brakes will be used and you will put out, and start to become effective at modulation, by means of this service membership brake manage.
(a) In the example of a trailer-tractor regarding unloaded reputation and you may an individual tool truck and this is capable of pulling a keen airbrake provided vehicles and that’s piled to GVWR, are able to meeting the needs of eight.1 by the process of your provider brake manage only, to the trailer heavens likewise have range and you may sky handle line of this new pulling car ventilated to your environment according to S6.1.14;
(b) Be capable of modulating air regarding the also have or handle range to your truck as this service membership braking system manage which have one failure from the towing vehicle provider brakes since the given for the 7.step 1.
8.step one Crisis stopping features. For strona randkowa dla krasnoludk??w every single trailer besides a truck converter dolly should keeps a great vehicle parking brakes one to conforms to six and therefore applies which have the fresh new force given into the 6.step 1 otherwise 6.2 if the air pressure throughout the also have line was at atmospheric stress. A truck converter dolly will provides, in the manufacturer’s alternative –
(a) A vehicle parking brakes one to conforms so you can 6 hence is applicable towards the force given for the 6.1 or 6.2 when the sky tension throughout the also have line was at atmospheric tension, or
(b) An emergency program you to automatically applies the service brakes in the event that solution tank is at one pressure more than 20 lb/in two in addition to have range is at atmospheric stress. 8.step one or, in the accessibility to producer, the needs of § of this label.
8.2 Supply line pressure storage. People single leakage variety of inability on services brakes (with the exception of weak of the also provide line, a valve myself attached to the also provide range or a component off a braking system chamber homes) should not result in the tension about likewise have line losing less than 70 psi, measured at the submit truck supply coupling. A trailer will meet up with the over also provide line pressure maintenance requisite using its brake system connected to the trailer sample rig shown when you look at the Profile step 1, toward reservoirs of your own truck and you may take to rig initial pressurized to help you 100 psi together with regulator of trailer decide to try rig put within 100 psi; apart from a trailer armed with an air-applied, mechanically-kept vehicle parking brakes and not designed to tow a vehicle equipped with sky brake system, at maker’s solution, get meet the requirements out of 8.cuatro instead of the ones from 8.2 and 8.3.
8.step three Automatic applying of vehicle parking brake system. That have an initial tank system pressure out-of one hundred psi and first also provide line stress out-of one hundred psi, if in case designed to tow an automobile armed with air brake system, that have an excellent 50 cubic inches take to reservoir attached to the bottom also have line coupling, sufficient reason for any subsequent single leaks types of failure in virtually any other brake system, regarding an associate built to contain compressed-air otherwise braking system liquid (similar to the parenthetical statement given inside 6.step 3.1), whenever sky pressure regarding the have range was 70 psi or even more, brand new vehicle parking brake system should perhaps not promote one braking system retardation as an excellent outcome of done otherwise limited automatic applying of the parking brake system.
8.cuatro Automated applying of heavens-applied, mechanically kept parking brake system. Featuring its brakes connected to the supply range portion of the fresh new truck try rig (Contour 1) in addition to regulator of truck shot rig put during the a hundred psi, and with one solitary leakages types of inability in the solution braking system system (except for a failure of your own also provide line, a valve yourself attached to the also provide range or a component away from a braking system chamber, but and additionally failure of every popular diaphragm), the brand new parking brake system will perhaps not render one brake retardation as the a results of over otherwise limited automatic application of the brand new parking brake system.
