Trailer technology options – It may be time to invest.
Vehicle safety technologies, such as advanced driver assistance systems (ADAS) and autonomous vehicles, are frequently in the news. Trailer technology is also quietly becoming more effective and affordable, but many carriers have been slow to adopt.
With trailers, the central focus is increasing fuel efficiency with aerodynamics and emissions reductions on refrigerated trailers. Trailer telematics and safety technologies have grown in popularity in recent years. This article will provide an overview of trailer technology options to improve safety and loss prevention results.
Current trailer technologies
An investment in trailer technology must have a short payback, which is even more challenging when there are usually two to three trailers per truck.
Trucking companies are generally interested in affordable options that help save time, retain drivers, meet customer demands, and avoid cargo claims. There is a growing interest in the following trailer technology options:
- Refrigerated trailer telematics
- Trailer tracking and sensors
- Cargo cameras
- Tire-pressure monitoring systems (TPMS)
- Trailer stability and braking warning systems
1. Refrigerated trailer telematics
Refrigerated (reefer) carriers have been increasing the use of telematics to remotely monitor and control the status of the trailer and the perishable products they haul. Food safety, as well as food quality, is their top priority. The latest trailer telematics allows carriers to:
- Remotely change the operating mode to off, continuous, or start/stop.
- Reduce load rejections for food safety or quality by providing proof of load and ambient temperatures during transit.
- Meet customers’ contractual temperature monitoring requirements and aid compliance with the Sanitary Transportation of Human and Animal Food rule.
- Verify the reefer fuel level and avoid running out, which puts a load at risk.
- Reduce expenses on maintenance and other trailer operating costs.
More advanced reefer units can alert carriers and drivers to problems before product damage occurs.
2. Trailer tracking and sensors
Trailer tracking has been made more affordable and reliable with improvements in battery recharging and sensors. Sensors can indicate:
- How long a trailer has been at a location,
- If and when the cargo doors have opened or closed, and
- Whether the trailer is empty or loaded.
Some customers use trailers as a rolling warehouse. Telematics data helps justify demurrage (per day trailer use charge) or when to move the trailer to a more efficient customer.
Knowing the location and status of trailers also helps:
- Reduce driver time searching for trailers and improve on-time service,
- Enhance revenue generation, and
- Increase visibility to high-value shipments when disconnected from trucks.
3. Cargo cameras
Drivers take breaks from the truck, so around-the-clock monitoring is not feasible with one driver.
Cargo thieves are diligent at staking out good places and times to steal cargo. Cargo cameras can help identify the thief, location, and time of the theft.
Cargo cameras also help confirm:
- The percent trailer cube utilization after loading or partial unloads;
- Cargo damage; and
- Trailer cleanliness and the presence of dunnage (pallets, straps, or garbage).
4. Tire Pressure Monitoring Systems (TPMS)
Drivers still thump trailer tires with a solid pipe or other devices to check for under-inflation. Not exactly precise. TPMS has been widely available on vehicles for quite some time. However, TPMS is recently becoming more reliable and affordable for carriers to consider on trailers.
Tires are the highest maintenance cost for most carriers. Under-inflation significantly reduces fuel efficiency and increases the risk of a blowout. Investing in a system that alerts drivers to low tire pressure can save time and money. Tread depth still has to be checked, but real-time air-pressure alerts will minimize the cost and safety risks of under-inflated tires.
5. Trailer stability and braking warning systems
Anti-lock braking systems (ABS) are required on trailers. However, trailer tilt sensors can alert a driver to an unsafe angle, or more advanced roll stability systems can automatically apply the brakes before a driver senses a trailer is going to tip.
Emergency braking alerts flash brake lights, so drivers behind the vehicle know the unit is stopping or drastically slowing.
Keys to remember:
Vehicle safety technology must have a payback to support the investment. Since carriers usually have two to three trailers per truck, trailer technology can be even harder to justify but may be the right move for your operation.
