How should air and electrical lines be positioned from the tractor to the trailer?

The positioning of air and electrical lines from the tractor to the trailer is crucial for safe and effective operation. Having these lines secured but with enough slack for turns is essential because it allows for the natural movement and articulation that occurs when the tractor and trailer are navigating corners or making sharp turns. If the lines are too tight, there is a risk they could become damaged or disconnected during these maneuvers, leading to potential safety hazards such as loss of braking ability or electrical failures.

Maintaining a balance between security and slack is important to ensure the lines do not hang too loose or sag. This prevents them from getting caught in moving parts or creating a tripping hazard. Additionally, proper positioning protects the integrity of the connections and the functionality of the air brakes and electrical systems, which are vital for the safe operation of the trailer.
