Drivers are the key component of any truck fleet, and keeping them comfortable at work is crucial for productivity and efficiency. They’re also a valuable resource – when Europe is facing a serious shortage of truck drivers that shows little signs of improving, making sure your drivers are satisfied is more important than ever.
When comparing couplings, finding the right combination of efficiency-boosting features and performance values can often mean one vital detail gets overlooked – driver comfort.
There’s plenty of features in truck and trailer design that impact driver comfort, but in this article, I’ll focus on those related to your choice of coupling.
Dampening and shock absorption makes a noticeable difference
When a goods vehicle is on the move, vibrations from the trailer can be transmitted through the coupling and into the driver’s cabin.
On short, low-speed journeys, like short trips around a construction site, this usually isn’t a major problem. But on long-haul trips on public motorways with a heavy load, these vibrations can become seriously uncomfortable and distracting. The driver’s focus is affected, they get fatigued more easily, and their overall efficiency goes down.
Long-term exposure to vibrations can even cause health issues – for example, back and joint pain, which can add to the pain caused by prolonged sitting and heavy lifting that truck drivers are already prone to.
Fortunately, there’s a few ways to minimise vibrations:
- Choose the right coupling – High-quality couplings have generous levels of shock absorption thanks to heavy-duty rubber components that dampen movement and vibration coming from the trailer. More generally, a high-quality construction with tight tolerances means the individual parts of the coupling system move around much less during operation – preventing sudden bumps and shocks while driving.
- Service your coupling regularly – Even high-quality couplings designed for comfort can cause problems if they’re not serviced properly. Wear and rust on key components can affect performance and impact the driver. Rubber shock-absorbing components, for example, can degrade and perish over time and eventually stop doing their job. Rust on the coupling’s moving parts can get them stuck in place, transferring movements and shocks from the trailer directly to the towing vehicle. And wear to components like the coupling’s bolt often leads to more rattling and unwanted movement. With regular inspection and service, you can avoid problems like these and ensure a smooth ride for the driver.
Air-assisted couplings make uncoupling easier
Driver comfort doesn’t just apply in the cabin – even the operation of the coupling itself has an important role. A manual coupling is simple and usually inexpensive, compared to other couplings – but the driver has to be right next to it to open it. Sometimes they need to get into unergonomic positions to reach it, and if the handle is stiff, uncoupling a trailer can become an annoying job that carries a risk of injury.
With an air-assisted coupling, some manual work can be eliminated – the driver still needs to leave the cabin and connect the coupling to the truck’s air system when it’s time to uncouple, but the bolt is opened by air pressure, not by the driver operating a handle. This saves time for the driver and means they completely avoid getting into tight spaces or unergonomic positions.
Improve driver comfort – and reduce maintenance costs
Giving drivers a comfortable, strain-free working environment where they don’t get injured isn’t just the right thing to do – it’s also a smart financial decision. Drivers that are injured need time off work, which increases costs in the fleet while lowering productivity. And if excessive vibration can injure a driver, imagine what it can do to the vehicle – the kind of shocks and jolts that make life unpleasant for the driver also place tremendous forces on the entire coupling assembly, leading to premature wear and more frequent maintenance issues.
In other words, choosing a coupling that offers the maximum level of comfort while also being suited to your application is a wise investment. If you need help finding the correct coupling solutions for your fleet, get in touch to let us know your needs and we’ll make a recommendation.
