Heavy goods vehicles (HGVs) in their typical tractor and trailer combination are the foundation of today’s logistics. Beside protection from overload, payload optimization is a key factor to remain at the top end of a very competitive industry. With own manufacturing and in house R&D VPG Onboard weighing are your reliable partner with decades of experience. We are one of the market leaders for a reason.

Heavy Goods Vehicle Payload Control

The high-quality 5th Wheel & Air system combines precise air pressure sensors on the trailer with additional sensors mounted to the 5th wheel. The air pressure sensors measures the load in the trailer’s air suspension system. For even higher system accuracy, two of VPG Onboard Weighing’s high accuracy load cells are mounted under compatible fifth wheels on the tractor. Typically installed within one working day, the system achieves an accuracy to ±1.5% GVW or better, providing net payload and gross vehicle weight measurements to boost efficiency as well as overload alarms for safety purposes.

VanWeigh units are worth their weight in gold!

Nick HatchettStores Supervisor, Booth Dispensers Ltd, UK

I have just ordered our fourth VanWeigh system in two years for our growing fleet of VW Crafters. VPG Onboard Weighing fitters are polite, courteous and well trained in their knowledge of the units being fitted. Vehicles are left clean, tidy and ready for work. 

The VanWeigh units themselves are worth their weight in gold. There is no fiddling about to add up weight, just load the vehicles and the unit does the rest. Drivers can see straight away if they need to alter their load to spread the weight.
