Keeping your work truck and equipment from being stolen means having a multi-layered security system, here is what you need to know

By Peter D. DuPre


Whether we like it or not, the trucks and equipment we use everyday for business and personal use are prime targets for thieves.

According to the National Equipment Register (, which keeps tabs on equipment thefts, hundreds of millions of dollars worth of mobile equipment is stolen from construction sites and farms throughout North America every year. Most of this equipment is never recovered.

And if you take just a minute to think about it, the reasons are obvious: Job trucks, trailers, and equipment are often left unattended at the jobsite or office after hours, when darkness makes theft or vandalism very easy.

Such targets of opportunity are lucrative for the thieves and costly for the contractor. Even a modestly equipped diesel work truck can easily have a $50K price tag. Add in the replacement cost of tools, a trailer, and a compact loader or skid steer (the highest equipment on the current “hit” list) and you’re easily out another $50K.

Sure, most businesses carry insurance to cover losses from theft and vandalism, but it only pays for the loss of the vehicle(s), trailer and equipment.

However, you might not get full replacement value for your loss and you certainly won’t get paid for lost business, time spent with the police and insurance agent, or for the time and out of pocket expenses it will take to replace all that you have lost.

Insurance is an important protection device, but it should be one that is rarely used. It is much better to protect your assets from theft and vandalism by making them unattractive targets.  Should the worst happen and your assets are stolen, then a security setup should be in place to track those assets and secure their prompt recovery by law enforcement.

Most of you usually lock your trucks, trailers and equipment when they aren’t being used and park them in secure areas. Some of you even employ alarm systems. But keeping vehicles and equipment safe and secure goes far beyond such basics and, in fact, is a multi-layered process.


Multiple Levels Of Security

The first part of keeping assets protected is to have the right frame of mind.

Many small contracting and landscaping businesses have only couple pickups, which also double as family and recreation transportation. This means that the owner has to be diligent about security 24/7 and the first place to start is with solid record keeping.

Keep accurate inventory records of all vehicles, trailers and equipment. For vehicles this means making a copy of the vehicle registration and insurance, keeping the title locked up in the office and not in the vehicle, logging VIN numbers, taking descriptive notes and taking color photos of the front, sides and rear of the truck(s).

Keep these in a safe or a safe deposit box and give a copy to your insurance agent. An extra copy of important papers to be kept at home is also a good idea.

After that, focus on security beyond locking doors and parking trucks and trailers behind chain-link fences and well-lit, frequently patrolled lots.

Realize that removing ignition keys and locking doors is not enough to keep vehicles safe; a thief can pop an OEM door lock in less than 30 seconds and be driving your truck and trailer away in less than a minute. And hot wiring a piece of equipment can take even less time.

The next step is to use theft deterrents such as battery cut off switches, ignition lockouts, fuel shut-offs, wheel and hitch locks on trailers, audible alarms and vehicle immobilization products.

These devices may not stop your vehicle from being stolen, but will slow the thieves down, which means that they will probably move on to easier targets.

Over the past few years the advent of computer technology, global positioning satellites (GPS) and cell phones has given rise to sophisticated anti-theft systems that can tell you where your vehicle and/or equipment is 24 hours a day, every day.

Thanks to GPS it is now possible to track the location of an asset as often as every three seconds, and if that asset is moved, the tracking software will alert you via an email or cell phone text message so you can alert the local police.

Depending upon the tracking system used, it is possible to activate the security device when the asset is moved beyond a certail area, turn on or turn off the engine, sound the lights and horn, lock and unlock doors, shut off fuel and even perform vehicle diagnostics.

The advantage of most hard-wired systems is that they usually disable the vehicle as well as allow you to track it via GPS technology. On hard-wired alarm and tracking systems, the wiring is hidden in with the vehicle’s wiring harness and sometimes within an armored cable, making them very dependable … as long as the vehicle has battery power.

Unfortunately, these systems are often difficult to install on construction equipment and are completely useless on trailers without an electrical source. They are also dependent on cell phone reception. Poor cell reception, poor security.

Installation on hidden, hard-wired systems can also be also costly if you don’t have the specialized skills needed to to do the job on modern, computer-interfaced automotive machinery.

A better choice for smaller companies is the use of portable GPS tracking systems, such as those offered DeWalt ( and USFleet Tracking (

Trackers like these are simple to install, run on self-contained batteries (up to three months) or other power source, attach via magnets or screw mounting and can easily be moved between vehicles, equipment and trailers. The providers offer a variety of options. You can use them to protect your box trailer during the week and your ATVs on the weekend.

Whether you opt for portable or a hard-wired GPS alarm/tracking system, the features are pretty much the same. Both systems will email or text your when an asset is moved and both will usually let you set up an electronic fenced perimeter and will notify you when that perimeter is violated.

The big difference in systems really comes down to service fees, which can vary widely, and whether or not the unit contacts you directly or through the service provider.

Finally, the advent of cell phone apps is opening up the ways in which GPS tracking systems can be accessed. Blackberry App World has a number of available applications, some of which are free, while some require a modest payment (up to about $15).

Although there are currently no GPS asset tracking apps available for iPhone, but they are being developed and will soon be available. Speak with your equipment supplier about your needs and they will probably develop one for you.


Save On Insurance

Many insurance companies offer substantial discounts on polices for vehicles and equipment that have sophisticated anti-theft devices and GPS tracking systems installed. Discounts may not be offered in all areas or by all insurance carriers, and the amount of discount may differ depending upon your locale; check with your agent to see if you qualify. The following list of insurers were known to offer discounts as of press time:

Top Jobsite Equipment Thefts

Although security of jobsite equipment is better than ever, thefts of equipment during after hours are at an all time high because most jobsites sit idle during nighttime hours, the equipment is easy to steal and the rewards, for the thief, are very high. What the two studies show is that no type of construction, landscape, or farm equipment is safe from theft.

The National Equipment Register, an organization that maintains databases of equipment ownership, theft reports, and machine identification characteristics. Their March 2011 Equipment Theft Summary lists the top five types of equipment stolen this past winter in order of theft popularity:

1.  Skid Steer Loader/Compact Tracked Loader
2.  Utility Cart/Vehicle
3.  Backhoe Loader/Tractor (Compact, Utility and Ag)
4.  Commercial Mowers
5.  Loaders (Articulated, Tracked, Landscape)

According to the 10th Annual Construction Equipment Theft Study, popular jobsite equipment is often a theft target because work areas are frequently free of personnel after dark, the ease in which these items can be transported and the high resale the equipment brings on the black market. The top five types of equipment are listed below in order of theft popularity:

  1. Generators/Air Compressors/Welders
  2. Backhoe Loaders/Skip Loaders/Wheel Loaders/Track Loaders
  3. Skid Steers
  4. Light Utility Vehicles/Work Trucks/Trailers
  5. Forklifts/Scissor Lifts
