Every seasoned truck driver is experienced enough to readily identify the truck air brake hose coils that run between tractor and trailer. However, for an inexperienced driver, the hose coils might be a mystery. We want to shed light on that mystery by explaining how they work and what their purpose is. To that end, in this post, we will be providing you with a holistic picture on the functionality of hose coils.
First and foremost, the average set up involves two hoses and one electrical cable. The blue and the red hoses are used to operate the air brakes on the trailer while the green cable provides electrical service. Most of the time the three can be seen dangling independently.
The Benefits of Air Brake Hose
Trailers obviously need their own brakes and lights in order to be road legal. But it would be nearly impossible to create independent systems to make them function. Therefore, the trailer’s brakes and lights are connected to the systems on the tractor by way of electric and hose coils.
Using straight hoses is entirely possible, and some drivers prefer that set-up. But straight hoses have an inherent flaw. In order to compensate for the wide turns that 18-wheelers have to make, hoses have to be sufficiently long enough to carry the distance as tractor and trailer separate on a turn. All of that excess hose is then left to hang freely once the rig straightens out again.
This presents a problem in as much as hanging hoses could easily be damaged by road debris and wind. The solution is to deploy truck air brake hose coils instead. Coiled hoses do not dangle. They act like springs, stretching out as tractor and trailer separate and retracting as they come back together. The hose coil design eliminates dangerous dangling and reduces the risk of damage.
As good as the coil design is for truck brakes and electrical systems, they do possess some challenges. First is the tendency of truck air brake hose coils to get tangled. Think of it in terms of a coiled telephone cord. If you are old enough to remember them, coiled telephone cords tend to get tangled after just a couple of weeks of use. And once they tangle, they can be difficult to get untangled. If a brake hose coil were to tangle en route, the next turn could pull air hoses right out of their couplings.
The other inherent weakness is that hose coils tend to be more prone to severe temperatures in either direction. Because there is more material to work with, and that material has to remain flexible, severe temperatures can cause cracking and breakage. Fortunately, this does not happen all that frequently thanks to the superior materials manufacturers now use.
