Now we’re in the depths of summer, you may be settled in your sun lounger wondering why all trailer couplings from VBG are red? Maybe you’ve been pondering what VBG means? Or why VBG coupling bolts come in 57mm as standard? You need wonder no more! We have the answers to your queries right here!
VBG is an abbreviation for Vänersborg and it was something that founder Herman Krefting noted when he decided on the name Vänersborgskopplingen, which has been developed over the years and come to be known as VBG. Since its origins more than 70 years ago, the business has continued to grow in the town of Vänersborg.
Our couplings haven’t always been red in colour. In the 1970s, VBG couplings came in a variety of colours. These colours distinguished between the different models in the range. The red edition is the one to have survived and is now seen on all couplings from VBG.
"The most important part of a coupling in terms of traffic safety is the bolt" said VBG’s founder Herman Krefting. When Herman began to think about how he could increase road safety, it was the bolt he identified as the most crucial part of the coupling. To create a reliable and durable coupling, he increased the dimension from the previous standard to 57mm ∅. VBG’s 57 mm bolt is treated using the hard material manganite and has become the present-day Swedish standard.
The first coupling, the TYPE 101, had a 57mm bolt and was launched onto the market in 1951.
Innovation is one of VBG’s watchwords. Here are just a few examples of how at VBG we have worked together with drivers to make their working day safer and easier.
The rotating bolt has been a VBG standard since 1998 and is advantageous both in terms of extended the coupling’s service-life and increasing product safety. The rotation helps to make wear and tear across the whole bolt more symmetrical.
Since 1994, the EU Directive has required trailer couplings for heavy trailers to feature two mechanical locks while also allowing for the coupling to be opened manually, even when a power actuator is present. As a result, VBG couplings always feature a manual handle regardless of the mode of operation selected.
VBG’s couplings feature two different attachment systems for drawbeams, and these are used for different types of rig and transport.
Trailers fitted with an articulated drawbar that is not exposed to any vertical forces can fit the most comfortable coupling offered by VBG. This is equipped with substantial rubber elements that ensure a smooth passage between the vehicle and trailer.
If you need to tow all types of trailer, then VBG’s Universal attachment system is the perfect solution. This system is designed with smaller rubber elements since it must distribute both vertical and horizontal forces imposed on it by the trailer.
The mechanism consists of many components, but it is only on the coupling bolt that the wear limit can be determined. Since all components undergo wear, the whole mechanism needs to be replaced for the sake of safety and to ensure functionality.
VBG endeavours to take long-term responsibility for our products and customers. This is why a wide range of spare parts and substitute products are available for both our current and discontinued products.
