Also,(and this really is teaching granny to ■■■■ eggs) if the trailers too high, push, not pull, the winding mechanism on the leg winder in and this will engage the low ratio gearing and you will be able to lower the trailer down to the d plate.
Keep turning, the trailer is def moving even though it might not appear to be.
Obvious if you know, but we all had to learn this once upon a time.
Be safe out there …

Don’t do what I done once and that is miss the pin whilst trying to hook up to a trailer dropped too high without checking, shearing one of the unit’s rear air tanks off and resulting in it losing all its air, as well as taking out the crossmember between the landing legs and both the unit’s light clusters!
That’ll teach you to use the air suspension control box in future instead of being one of those that relies on the ramps doing the work, deposting all the fifth wheel grease on the catwalk and lines.
I don’t think that you have properly read the first paragraph of my previous post. I do NOT rely purely on the ramps on the back of the unit to pick up a trailer that’s dropped too low and I will if necessary adjust accordingly with the suspension controls. I have since learned from that mishap and am taking steps to stop from it happening again.
RE: the maoster: When I used to work for an outfit that pulls boat trailers for P&O, the trailers at Teesport were often dropped way too high by their shunters, leaving a decent gap after maxing the ride height (on a Stralis), and as a result, spending a good five or ten minutes slow-winding the legs!

Didn’t your instuctor teach you this? or are you such a bad troll you forgot about IT all in 2 months
There was no need at all for such a callous post!
The OP was just asking a simple question on one of the basic aspects of being a lorry driver. Dropping and hooking up a trailer a few times on your training doesn’t mean that you’ll master it during that time.
Trailers are sometimes dropped on rough ground or by a driver who needlessly pumps their suspension up to the max before dropping their trailer, resulting in the next driver who’s needing to pick it up having great problems because their unit’s ride height doesn’t go up as high as the previous driver’s, and they may have to painfully slow-wind it down to the height of their unit (or whistle up a Terberg if you’re lucky enough to have one in the location that you’re picking it up from).
There’s is no such thing as a stupid question, so if you don’t have anything helpful to contribute to this forum, just zip it!
May have already been mentioned but as a relatively new driver myself, always use both mirrors, i have a habit of always just lining it up in my drivers side mirror. In the new generation scania’s the mirrors seem to distort at the bottom, so you line up bang on in the mirror but you are actually well out of line
Moral of the storey get out and check… i went to pick up a trailer and the fifth wheel was pointing up… so went to go under and bang… smashed the air line connectors on the trailer
