5 Pro Tips for Wood Hauling Safety

Beyond ensuring your trailer lights are functioning correctly, here are five pro tips to enhance your wood hauling safety:

1. Proper Load Distribution: Distribute the weight of the wood evenly across the trailer. Place heavier logs towards the front of the trailer, over the axle. This helps to prevent swaying and improves stability. Aim for a tongue weight of around 10-15% of the total trailer weight.

   • Why it matters: Uneven load distribution can lead to dangerous trailer sway, making it difficult to control your vehicle.
   • My experience: I once hauled a load of firewood where I stacked most of the wood towards the rear of the trailer. The trailer started swaying violently at highway speeds, and it was a terrifying experience. I learned my lesson the hard way!

   • Secure the Load: Use heavy-duty straps or chains to secure the wood to the trailer. Ensure the straps are properly tightened and that the wood cannot shift or fall off during transport. Use a crisscross pattern when securing the straps for maximum effectiveness.

   • Why it matters: Loose loads can shift during transport, causing instability or even falling off the trailer, creating a hazard for other drivers.

   • Best practice: I always use at least four straps to secure a load of wood, even for short distances. I also check the straps periodically during the trip to ensure they remain tight.

   • Check Tire Pressure: Before each trip, check the tire pressure on both your vehicle and trailer tires. Inflate the tires to the recommended pressure specified on the tire sidewall or in your vehicle’s owner’s manual. Also, inspect the tires for any signs of damage, such as cuts, bulges, or excessive wear.

   • Why it matters: Underinflated tires can overheat and blow out, while damaged tires can fail unexpectedly.
   • Key metric: Maintaining proper tire pressure can improve fuel efficiency by up to 3%.

   • Drive at a Safe Speed: Reduce your speed when hauling wood, especially on rough or winding roads. Allow for extra braking distance and be aware of your surroundings. Remember, the heavier the load, the longer it takes to stop.

   • Why it matters: Speed is a major factor in accidents involving trailers. Reducing your speed gives you more time to react to unexpected situations.

   • Expert advice: I always reduce my speed by at least 10 mph when hauling wood, and even more in inclement weather.

   • Regular Maintenance: Regularly inspect your trailer for any signs of wear or damage. Check the lights, brakes, tires, and suspension. Lubricate moving parts as needed. Address any issues promptly to prevent them from escalating into major problems.

   • Why it matters: Regular maintenance helps to ensure your trailer is in safe operating condition and can prevent costly repairs down the road.
   • Maintenance schedule: I recommend inspecting your trailer at least once a month, and more frequently if you use it regularly.

Case Study: The Importance of Trailer Light Maintenance

I once worked alongside a logger named Dale, a seasoned veteran with decades of experience. Dale was known for his meticulous attention to detail, especially when it came to safety. He religiously inspected his trailer lights before every haul, using a 7-pin tester.

One day, Dale was hauling a particularly heavy load of maple logs. As he was driving down a busy highway, he noticed in his rearview mirror that a car was tailgating him closely. Suddenly, the car swerved violently to avoid rear-ending him.

Dale pulled over to investigate and discovered that his brake lights had stopped working. A loose wire in the trailer connector was the culprit. If Dale hadn’t been so diligent about checking his lights, the situation could have ended tragically.

This incident underscored the critical importance of trailer light maintenance. It’s not just about avoiding fines; it’s about protecting yourself and others on the road.

Choosing the Right Wood for Firewood: A Quick Guide

While we’re focused on hauling, let’s briefly touch on choosing the right wood for firewood, as it’s often the end goal of wood hauling. Different wood types have different burning characteristics:

• Hardwoods (Oak, Maple, Ash): These are denser and burn longer, producing more heat. They are ideal for cold winter nights.
  • Oak: A very dense hardwood, oak burns long and hot but needs to be seasoned for at least a year.
  • Maple: A good all-around firewood, maple burns well and produces a good amount of heat.
  • Ash: Ash is easy to split and burns cleanly, making it a popular choice for firewood.
• Softwoods (Pine, Fir, Spruce): These burn faster and produce less heat. They are better suited for kindling or shoulder season fires.
  • Pine: Pine burns quickly and produces a lot of smoke, but it’s readily available and inexpensive.
  • Fir: Fir burns hotter than pine but still produces a good amount of smoke.
  • Spruce: Spruce is similar to fir in its burning characteristics.

Seasoning is Key: Regardless of the wood type, it’s crucial to season it properly before burning. Seasoning involves allowing the wood to dry for at least six months, preferably a year or more. This reduces the moisture content, making the wood easier to light and burn more efficiently. Ideally, firewood should have a moisture content of less than 20%.
