Having vast experience in axle weighing means that we know all about the see-saw effect.
But not everyone, including some that have been in transport a long time are aware of what can happen when the load is incorrectly positioned on the vehicle.
A training exercise for transport and depot managers at one of the major builders merchants produced an interesting reaction from those attending when we showed them what happened.
Placing a set of portable weighpads, correctly set up and on flat level ground, beneath the front axle of a 2-axle rigid we then got them to place a couple of pallets of bricks right behind the cab. With plenty of space left on the load bed our audience were genuinely surprised to learn that the vehicle was now illegal because the front axle was overloaded.
We then put some pallets behind the back axle. And again there was genuine surprise when everyone learnt that, even though the overall weight had increased, the vehicle was now legal.
|Weighpads - great for driver and operator training.|
The action of putting load behind the back axle had caused the front axle weight to decrease.
The see-saw effect nicely demonstrated.
The issue of load distribution is often overlooked even by those with a great deal of experience in managing a fleet of vehicles but it is high point loads that cause most damage to the road surface.
Which is why there is a national network of axle weighbridges to check not only gross weight, but individual axle weights as well.
A vehicle can be well within its maximum gross weight but could be operating illegally because the distribution of the load is incorrect.
This is often a problem for operators with diminishing loads. The vehicle leaves the yard perfectly legal but as weight is removed from the rear, it is vital that the driver redistributes the load or the front axle can become overloaded.
As we said, even those with great experience may not be aware of this and have to have it demonstrated to them.
