The lack of airflow to the tires and brakes on drop deck enclosed trailers IS one of the problems. Interestingly enough, the race teams have one of the answers to this problem right at hand: The same automatic onboard fire suppression system used on the race cars can be rigged to work the same way on these trailers. I know of a couple people that have done this. I would also suggest that the teams invest in a system that can snuff out a fire on the inside of the trailer. A system large enough to snuff out the oxygen in the trailer would go a long way to keeping any fire that DOES ignite from getting out of hand. Heat and smoke sensors that would alert the driver need to be part of the system. I have also advocated a similar setup for combines that are known to catch fire. In 2007 Wayne Taylor racing lost their transporter, their equipment, uniforms, laptops, spare parts and the ONLY Dallara Daytona Prototype race car in existence. That kind of loss is worth investing in some fire prevention in my humble opinion.
That is s big problem for some of the freight company's that hire a lot of inexperienced drivers but most race teams hire pretty experienced drivers. I don't care how steep a mountain is I choose a gear that will maintain the engine at a certain rpm. Wheel bearings, tires, and electrical is the main reasons for hauler fires. Because we haul pit scooters and golf carts there are also a lot of battery fires in race car haulers. A few years ago a team that won the championship in pro stock at the last race on tour in Pomona Ca loaded their personal car in the trailer after driving to the store and got about 5 miles down the freeway and the catalytic converter ignited gas fumes in the trailer and burnt up the hauler and the championship car.Tire fires and brake fires are fairly common especially if steep downhill grades are involved. It's pretty easy to do if you start down the grade too fast and the exhaust or Jake brakes can't hold it and you have to use a lot of brake.
Every day when I do my pre trip I pull the chrome hub caps off our trailer and check the oil and I bump the tires every time I stop for any length of time.They are saying one possibility is a wheel bearing, a wet hub could have sprung a leak.
Any chance you're prior service? Those sound a lot like typical military pre-service checks.Every day when I do my pre trip I pull the chrome hub caps off our trailer and check the oil and I bump the tires every time I stop for any length of time.
