Semi Truck Air Lines – Every mix vehicle has 2 air lines. Theselines are the service line and also the emergency line. Theyrun between each automobile, such as tractor to trailer, trailer to dolly, and dolly to 2nd trailer.SERVICE AIR LINES.– The service line carriesair that is managed by the foot brake or the trailer handbrake. Depending on just how difficult the foot brake isengaged, the stress in the service line will similarlychange. The solution line is attached to relay shutoff(s)on the trailer to use more or less stress to the trailerbrakes.
As pressure boosts in the service line, therelay shutoff opens up and also sends out atmospheric pressure from the trailerair containers to the trailer brake chambers, therefore using thetrailer brakes.EMERGENCY AIR LINES.– The emergencyline has 2 functions. Initially, it supplies air to the trailerair containers. Second, the emergency situation line manages theemergency brakes on the combination lorry. Loss ofair pressure in the emergency situation line triggers the traileremergency brakes to activate. The pressure loss couldbe triggered by a trailer breaking loose and also tearing apartthe emergency air hose.
The loss might also be the resultof a pipe, steel tubes, or other components breaking andcausing an air leakage. When the emergency situation line losespressure, it additionally triggers the tractor rotection valve toclose, causing the air supply knob to stand out out.Emergency lines such as tubes couplers, and otherparts, have a red covering. The red covering allows youto different the emergency lines from the service lineswhich have a blue covering.Hose CouplersHose couplers, typically called glad hands(fig. 7-11), are coupling tools made use of to connect theservice and also emergency air lines from the vehicle or tractorto the trailer.
The glad hands have rubber seals, knownas rubber grommets, that protect against the air from escaping.Clean the rubber grommets prior to you link the gladhands. When linking the glad hands, press the twoseals together with the glad hands at a 90-degree angleto each other. A turn of the glad hands attached to thehose signs up with and also secures the couplers.Some automobiles have “dead end” or dummy gladhands to which the hose pipes need to be attached when notin use. This protects against water and also dirt from getting into theglad hands and also the air lines. This is really importantbecause keeping the air system clean is an important aspect.
