Tire air pressure is also critical to ensure the load weight is properly supported. Regular tire inspections ensure the tires have plenty of tread and are free of other damage, such as warping or cracking. Tire Problemsįinally, semi-trucks cannot afford to have a blowout or other tire trouble when they’re on the road. Common problems include broken spring hangers and leaf spring leaves, leaking shocks, a cracked torque road or u-bolts, and air suspension system failure. Trailer suspension also keeps the rig’s axles in place, and broken suspension parts can be dangerous. Crucial suspension parts wear down quickly on semi-truck trailers. Suspension FailureĪ semi-truck trailer’s suspension protects the load and helps the wheels handle the load’s weight. Regular inspection of the trailer’s electrical system is crucial to ensure you don’t end up with a lighting issue or refrigeration failure on the rig during a long or short haul. Depending on the trailer type, an independent electrical system will maintain climate control in a refrigerated trailer, hydraulic control on platform trailers, and the trailer’s air brake system. Trailers are an extension of the semi-truck’s cab, as are the trailer lights. It’s also important to ensure the doors on framed trailers seal as they should. It’s important to inspect the trailer’s stability, especially the roofs of framed trailers, to ensure no structural weakening, cracks, holes, or leaks. Structural damage weakens the trailer, and this could lead to a devastating failure. Whether flatbed or framed, the trailer body must remain in good shape to house and protect the load during the haul. Because the trailer hauls the load, the brakes must be in the best condition possible to ensure they can stop the rig even when weighed down. The trailer has an air brake system that must be checked regularly for pressure leaks, the most common problem, and other issues. Maintaining the trailer braking system is crucial to the rig’s safety and reliability. Brake System TroubleĪ semi-truck’s trailer has its own set of wheels and brakes to stop them. Here are five common problems we run into with trailers. The trailer also has a lighting system that must work when it’s dark to keep truckers safe. The trailer has the difficult task of storing the heavy load, which places incredible stress on the wheels, tires, and trailer suspension. The importance of semi-truck trailers cannot be overstated, which is why Midlane Truck & Trailer Repair maintains and repairs them.
