Maclean's Magazine: The Ernerst C. Manning Innovation Awards: Nuts for truck safety

By Chris Sorensen, Posted on Thursday, September 26, 2013

Excerpts: “In 2008, there had been 95 fatalities in the U.S. and Canada due to wheel-loss situations, and just under 6,000 incidents,” Davies says. “I thought, ‘There is a market for some kind of device to hold the nuts in place to stop these kind of accidents.’ ” What he came up with was the Zafety Lug Lock, a small piece of plastic that links two bolts on a truck’s wheels, effectively freezing them in place. the name Taffy, spent nearly three years on his sailboat with partner Lori Maguire- an extended sabbatical from his vice-precident's job at a real estate development firm..."

...There have been some unexpected developments, too. Davies says he has been approached by an oil and gas industry executive seeking a way to keep the nuts on a pipeline’s flanges from coming loose. “If it keeps the nuts on the wheel of a big truck, it’s sure as hell going to keep the nuts in pace on a pipeline,” Davies reasons.

Senior Technical Editor Paul Abelson braved the stifling Dallas August heat to scour the aisles of Great American Trucking Show to bring you highlights of the most innovative and practical new products out there.
By Paul Abelson senior technical editor

Despite better maintenance, loose wheel incidents still occur, often with disastrous results. As temperatures change, metals expand and vibration can loosen wheel nuts. When surface rust or corrosion occur, further wheel end vibration loosens nuts. Some devices show when loosening has happened, but the Zafety Lug Lock, 888-381-2355,, actually prevents hub-piloted lug nuts from backing off. Made of polymer, shaped to fit over two adjacent wheel nuts with a corrugated connector bar between to absorb any differential vibration, four or five locks are used per wheel, depending on configuration. They hold the corners of the nuts to keep them from backing off. During inspection, you can easily verify that all nuts are in proper position.

Frequency of occurance, current best practice, and potential solutions

The Zafety Lug Lock system helps prevent lug nut loosening, wheel damage and potential wheel loss by securing two adjacent wheel nuts together to minimize their ability to rotate and loosen. This design, along with a pre-engineered blend of high-tech thermoplastic resins, provides a high strength-to-weight ratio that retains its flexibility. The system has been proven effective in independent testing. Zafety Lug Lock excels in extreme operating environments, says the company, including chemical exposures and temperature ranges. The system provides a clear visual check of lug nut security and is available in Standard and High Temperature formulations for severe braking applications.

Heavy Vehicle Wheel Detachment

Frequency of occurance, current best practice, and potential solutions

When a wheel becomes detached from a heavy vehicle it may simply come to rest without causing any further damage or harm. However, in the wrong circumstances, it can collide with other vehicles or road users and cause an accident and, in some cases, this has resulted in fatalities. Typically, it is only the more serious accidents that occur as a result of wheel detachment that are identified by standard reporting mechanisms. Such detachment of wheels from vehicles, particularly heavy commercial vehicles, has been a cause of concern for many years and there has been a considerable amount of investigative work and comment on the subject. In 1997, the Department for Transport (DfT) published an advice leaflet (“Careless Torque Costs Lives”) with the intention of reducing the scale of the problem. Despite this previous research, comment and advice, there is evidence to suggest that wheel detachment still occurs. There is, therefore, a need to more accurately quantify the current frequency of wheel fixing problems and to assess current practices within the industry in order to assess whether the previous advice has had a beneficial effect and to identify new action that could be taken to reduce the scale of the problem. The research was funded by the DfT and this report describes all of the work undertaken and the results and conclusions drawn from it…

…The report recommended that consideration was given to routinely monitoring the frequency of wheel fixing problems, possibly through the use of the VOSA prohibitions database combined with detailed exposure data. It also recommended that consideration be given to further work to investigate improvements such as:

Further standardisation of best practice wheel tightening procedures, in particular, simplifying the identification of recommended torque settings and standardising on the use of lubrication.

Further education and or enforcement to encourage universal adoption of rigorous wheel maintenance procedures.

The possibility of a fundamental re-design of the method of wheel attachment for heavy vehicles to produce a much lower maintenance solution.

The potential mandatory use of wheel nut retention devices or movement indicators, if independently shown to be effective.

Topline Trailer Services

We were introduced to Zafety Lug Locks a year ago and have had great success in using them in our business. They are a very useful safety measure and our customers are pleased with the results.

After torquing wheels to 450-500 FT. LBS., we install the Zafety Lug Locks. Between services, checks are done to ensure there is no movement of wheel nuts and no extra torquing is necessary.

Customers are very satisfied with this remarkable product and the low cost to outfit a unit is a bonus. The locks can be used over and over again and this is also beneficial in keeping costs down.

We would definitely recommend this product to anyone.

...I have installed the Lug Locks on my 3 axle trailer. In the milk transportation business, the truck does alot of twisting and turning in the farm lanes and yards as well as backing into the dairies.

These Lug Locks are performing well in the short period of time that they have been on the unit. I anticipate that they will prevent the lug nuts from coming loose.

This does not mean that drivers will not need to check the wheels when they do their circle check , but it gives them confidence that this product is doing the job.

The Ace Group Logistics Specialists

We are a logistics company who have always practiced high safety standards and we were introduced in the summer of 2008 to a new product on the market called the Zafety Lug Lock. The time spent on the installation of the product was small and the benefits to our company can only grow. Our drivers have also commented on the help it has provided them in doing their daily circle checks. We will continue to add Zafety Luck Locks to our fleet when the need comes.
