    Any employer that would call it a preventable needs to be replaced ASAP.

    Story time....
    Pulling into a dock that requires a turn around in the space of 4 dock doors, so fairly tight. Turn around and start straightening and the red glad hand receiver broke in half. I was able to get out of the way by switching the red and blue lines around. A week or so later snapped another receiver on a different trailer, but this time taking the same type of tight turn in our yard. Noticed what was happening in such a tight left turn the air lines would drop below the frame and get caught on a bolt sticking out of the frame used to ground the batteries. After the second broken receiver the shop moved the ground and no more breakage. Never heard anything from management about it.

    My understanding is air lines dangling less than 12 inches above the catwalk is a DOT violation.

    §393.45 Brake tubing and hoses; hose assemblies and end fittings.
    (a) General construction requirements for tubing and hoses, assemblies, and end fittings. All brake tubing and hoses, brake hose assemblies, and brake hose end fittings must meet the applicable requirements of FMVSS No. 106 (49 CFR 571.106).

    (b) Brake tubing and hose installation. Brake tubing and hose must—

    (1) Be long and flexible enough to accommodate without damage all normal motions of the parts to which it is attached;

    (2) Be secured against chaffing, kinking, or other mechanical damage; and

    (3) Be installed in a manner that prevents it from contacting the vehicle's exhaust system or any other source of high temperatures.

    (c) Nonmetallic brake tubing. Coiled nonmetallic brake tubing may be used for connections between towed and towing motor vehicles or between the frame of a towed vehicle and the unsprung subframe of an adjustable axle of the motor vehicle if—

    (1) The coiled tubing has a straight segment (pigtail) at each end that is at least 51 mm (2 inches) in length and is encased in a spring guard or similar device which prevents the tubing from kinking at the fitting at which it is attached to the vehicle; and

    (2) The spring guard or similar device has at least 51 mm (2 inches) of closed coils or similar surface at its interface with the fitting and extends at least 38 mm (11⁄2 inches) into the coiled segment of the tubing from its straight segment.

    (d) Brake tubing and hose connections. All connections for air, vacuum, or hydraulic braking systems shall be installed so as to ensure an attachment free of leaks, constrictions or other conditions which would adversely affect the performance of the brake system.

    Just needs to not touch the catwalk. But that was the normal way the hoses were, it's just in a very tight turn, like when the cab was almost touching the trailer at a 90 degree is when the slack caused it to drop to be touching the frame. Even normal turns it never would have.

    The coil plastic air lines are junk , so are the glad hands.
    Be nice to have some cnc glad hands made.
    Not good to put your outfit in a 90 , puts everything in a bind what did the hose hanger look like.
    Who had the red dots on there trailers to keep from crushing the faring way back when.

    I’ve broken two my air lines would hook the exhaust shield and snap the gladhand in a tight turn. I repositioned my springs and loop the electrical cord around the airlines when hooking up it gave me the needed clearance

    YES, your fault 1000%

    you will now be flogged in the public square at sunrise on the 14th.

    this will be going viral, so make sure you have clean underwear (no skid marks)
