Safe Towing Capacity Made Easy


American Towman's Field Editor Terry Abejuela recently wrote an informative safety article, "How to Determine Safe Towing Capacity." Terry's narrative was dead-on accurate; but, some towers can't grasp the mathematical process necessary to understand it.

I'd like to coat-tail Terry's article and share an easy way to first remember the formula, and secondly how to apply the formula's components and ease into appropriate calculations. Let's look at it from another perspective.

For us towmen with non-mathematical minds, learning to calculate the STC formula is sometimes an intimidating task where it might be easier to bypass weight calculations by simply loading or towing the vehicle. When something's too hard, it's characteristic to ignore the proper process and take a chance.

An overloaded tow truck or carrier is an accident waiting to happen and a leading cause of tow truck crashes. When tow trucks or carriers are overloaded, two systems are immediately affected where they can't brake cleanly or steer. In the event of panic stop at an intersection, tow vehicles sometimes lose their ability to stop due to disproportionate weight over the tow truck's rear-axle and limited weight on its front axle.

Combined with a lightened front steering axle, the tow truck isn't able to steer in the path it's intended to go. Combine no brakes and no steering with other bad driving behaviors like driving at a too-fast speed, existing road conditions and distracted drivers, the end result is typically uncontrollable and deadly.

Take the Call

When calls come to the dispatch office, it's the dispatcher's job to accept calls and assign it to the next available driver and appropriate truck. But--can the responding tow truck or carrier safely handle the heavier weight and configuration of the vehicle or item(s) being towed or transported?

When tow operators call their dispatchers and say, "Hey, I think this thing's too heavy for my truck," here's where tow company liability becomes paramount. Many towmen have that solid gut feeling that they know they're overloaded. The problem? Owners, managers or dispatchers simply poo-poo the tower's premonition of danger, order them to take the tow and quit whining.

If your driver calls to tell you they're overloaded, you'd best heed their warning and consider other options.

It's All Routine

Towmen are not mathematicians. Calculating STC can be confusing; but, the simplicity of knowing the formula is likened to conducting a typical tow truck inspection. By starting the inspection at the front of the truck, then moving to the center and finally to the rear of the truck. Put this little memorable ditty into your inspection routine: front, center, rear.

If you routinely inspect your truck starting at the front, to center, and then to the rear; remembering how to calculate the formula of safe towing capacity is the same. It is the same as the industry standard below:

Example: The formula, 1/2 FAW x WB divided by OH, asks:

1. (Front) What is one-half the front-axle's weight (1/2 FAW)?

2. (Center) What is the wheelbase (WB) measurement?

3. (Rear) What is the overhang (OH) measurement?

I teach this process to towers, police officers and military personnel in my challenge to make learning the formula less confusing and memorable. By routinely making tow truck inspections the same thought process as how to calculate safe tow capacity, towmen can easily and accurately determine if their load is safe and doable.

By training your mind to recognize the similarity between the two processes, determining STC becomes an easier process. For safety's sake, we're hoping that towers look to safety by calculating STC for the load or vehicle they're dispatched to handle. By chanting, "front, center, rear" repeatedly, remembering the components and process to determine STC is easy. Learn it, chant it, apply it.

And, when you're at the next tow truck inspection, you can almost put it to-a-tune as you sing it to the tow boss.
