Hi I’ve not been on here for a while.
Have just got a full time job on artics. Im driving a double deck trailer
But every so often I feel it pulling me to the left and right.
I thought it could be loaded top heavy but after checking it wad ok
I only passed last july and enjoying it. But did crap my self when this happened
Driving a Mercedes actros. Up and down to north Hampton fortrec
Any advice bee good
Check there’s enough grease on the 5th wheel.
Is it just when you catch the grooves on the motorway?
Double deck wheels are smaller, so can make a noticable difference, although it can be quite bad in any vehicle.
not the wind blowing you ? lol
i have spent all week with an actros 1836 pulling a decker. that movement is likely to be the road surface so dont worry about it. just gently correct it and keep your cool
I think this sounds like motorway tramlines too. Don’t try to correct for it by waggling the steering wheel just hold it firmly in the dead ahead position.
Been pulling a double decker with an Actros every night for the last 9 years. Still not an expert but sounds like tramlines to me.
Deckers tend to make the cab “bounce” when there is too much weight at the back and not enough on the front. Also you will feel the trailer “tug” over bumps. Unfortunately very few forkies or even companies actually know how to load a double decker. Worst thing the government ever did was stop teaching physics as a separate subject

Good call that would be the first thing i’d look for, if the grease has all gone it can be reluctant to swivel…
Secondly make sure the 5th wheel isn’t too far forward, if it is it can cause some horrible sensations especially on corners.
Will check 5th wheel but I think it could be the motor way tramlines
As it only happen every so often on motorways
So ive had the habbit of reduce my speed.
Thanks and I will check 5th wheel
I too drive the DD on trunking and I would definately say it sounds like the motorway tramlines
I agree. Sounds like tramlines and they get exaggerated when you pull a decker with the extra swaying you get.
I doth my cap to you guys who drive Double Deckers and Triple Deck Car Transporters. With the state of our roads and motorways, you guys do well

Here here. I put down a lot of common-sense safe driving to knowing enough about Physics so you know what happens when you do this or that, without having to find out the hard way!

If its a run you are going to be doing day in day out, you will get to know were the worse tramlines are and be able to avoid them, no need to reduce speed just run along the lane 1/2 separation white lines, if there is a truck at the side of you run along the hard shoulder divider.
There is some vicious ones A1 south approaching Stamford, we all get caught out even if ya know were they are!
It will be worse in the summer when Tarmac starts getting hotter and sinking more.
It’s not really helping the problem but the best thing to do is in fact sit in them and let it do its work.
