This has been puzzling me for a while, I've seen many pictures of real and models of European heavy haulage trucks and have a simple question. When you use an ordinary truck that has a fifth wheel but it's going to tow a set of bogies they put a ballast tray on the fifth wheel, my question is how exactlly is the tray held in place so it doesn't slide about on the back of the truck.

on ours, we use 4 x twistlocks like you secure containers down with. 2 at the rear of the chassis and 2 at the front Dave

Dave Dose it have a king pin for the fifth wheel or just the four twistlocks.

They also have locking pins built into the chassis which the ballast box locks into. It isn't just held on the 5th wheel. I can't find a picture at the moment which shows it clearly but here's the back of one of GCS Johnson's - it has mounts for the ballast box built into the chassis.  Tim Ah....I see Dave has replied. I was going to use the container twistlock analogy too.

we've moved away from having a king pin under them and setting them all up for twistlocks.. we'd bent one with a pin therefore taking it out of service as we usually use the crane to fit them and having between 23-28tonnes swinging about plus when you put them on the floor that adds to the chances for damaging them ...and using the same mounting allows quicker set up time and more flexibility in the fleet, and looking at tim's pics...That ALE box was designed without asking the road staff..it looks an absolute pics to get on or off or see down the side of.. If memory serves me right from when we've borrowed the heanor box, it sits on a set of feet similar to where we put the twistlocks but you chain it to the chassis. Dave

Hi Dave, I would suspest ALE double the use of their ballast box as a tipper by the looks of it!  Paul
