no mavis rail = split couple. I have had managers and shunters watching me and nothing has ever been said to me. However if there is a mavis rail i couple/uncouple as i was shown for my 3a
I’m just interested, because I’ve never used a fridge on an artic, so never struggled for space. Do you have the option of moving the fifth wheel back permanently to make it easier?
im an agency bod and drive the agency trucks that they have at various sites. Our trucks do have sliding 5th wheels however i have been told never to touch them as they are set correctly for the axel weights and apparently takes to people a morning to get them right if they have been moved.
They hadn’t the sense to mark the sliders at the preferred position? they are however quite right about correct position for weight distribution, especially important with small wheel mid lifts which are surprisngly easy to overload at full weight if the fifth wheel is too far back.
As for the suggestions about pumping the air out, you can visualise the glee with which jobsworth will come mincing over in his shiny hiviz plus clipboard, ‘‘you’re wasting fuel with all that running’’ …minces off to report the miscreant to school leaver depot manager.
Er - When you’re pumping the brake pedal to get rid of unwanted air pressure you don’t have the engine running (as that would simply replenish the air tanks as fast as you’re draining them)…
Carryfast:
Pumping the air out and building it up again will probably also count as driving time during each trailer swap.
As opposed to some Palm couplings job done.

Beat me to it Lucy. I’m assuming he thinks that you’ll handball a load onto the warehouse racking also while you’re waiting for it to build up.

Er-one would think it obvious that an extended tickover (even fast idle) time would be in order to inflate the whole shebang, but thanks for the clarification +
And if you think that even max revs could keep up with pressing the brake pedal, you can’t have too many MANs on the fleet, even without fully exhausting the air circa 5 mins min to fully inflate at tickover.

As you know I have a new 22 plate megagigaspace thingy, fantastic motor with one exception! The air tanks must be recycled coke tins and the compressor must come from a camping shop where it’s designed use was to blow air beds up!
I was parked between two lorries a few months ago who’s drivers were still both sleeping when I started. I turned the ignition on and something ridiculous like 3 bar in the tanks. Not wanting to wake the other drivers I left it on tickover rather than fast idle whilst I did my walk around. It took 14 bloody minutes to build up enough air to even move off!
Then add to that insult you must have at least 10 bar of pressure before you can either raise or lower the suspension.

Remind me why are we pumping all the air out and then waiting to refill the air tanks to solve the OPs problem.
The ministry certainly won’t see it as break.Which leaves the question is sitting in the cab operating the controls and monitoring instruments defined as other work or driving ?.
Why would you need to pump the air out to twist a palm coupling together in which the tapered locking tabs apply the required clamping force to overcome the back pressure at the valve ?.

. the other option was to put te legs down and pullthe pin.
Does that mean you normally split couple?

Do you have no conception of weight distribution or axle loading?

But at some point you will need to start that engine and replenish those tanks.

I normally am running empty or only have about 3 pallets on the back so it’s not a concern usually for me.

Our entire fleet is currently MAN, with just one exception - which just happens to be the Renault that I normally use
Anyway, I gave it a try today. A dozen to 15 pumps on the brake pedal (to lose some air). Seat starting to wilt and steering column clamp inoperable so confirmed pressure now low. Connected lines and yes! the lines were indeed much, much easier to slip into engagement. Started the engine and counted to 10 while the pressure gauge rose to over 8 bar so good to go after maybe 15 seconds at fast idle (which the Renault manages all by itself). I’ll give it another try some time soon when I’m slumming it in a MAN
The significant point being that you’ve only got to replenish the air that’s been lost from the unit’s own tanks - it’s not the same situation as coupling up to a trailer that’s been sat (loaded) on its arse for a while where you’ve got to replenish the (empty) trailer tank, the air bags and the brake chambers on 3 axles…

You really are something special, aren’t you? Time spent stationary while coupling/uncoupling, securing the load, checking paperwork, cleaning the lamps & reflectors, doing walk-around checks and all the other stuff you do while the wheels aren’t turning is “Work”. Always has been, probably always will be. Time when the wheels are turning (and brief interruptions of a minute or so due to traffic conditions etc) is “Driving”.
Anyone familiar with driving a LGV any time during the last 35+ years will immediately grasp these concepts…

Anyone familiar with doing a proper trunk run will grasp the concept of the grey area between what the ministry will define as driving off road v other work.
Also the concept of minimising time spent during trailer swaps and maximising the break time.Which certainly doesn’t mean pumping all the air out then waiting to build it up again every time you pick up a trailer.
Good luck with booking a traffic jam taking one or two hours to get through as other work or break even with 45 minutes between moves.

WTF are you on about
1 there is no need to use any manual force to overcome the back pressure against the shut off valve in the case of palm couplings.So weaklings welcome.
2 No need to pump the air out of the tanks using the foot brake valve and then waiting for the engine air brake compressor to refill them again in view of 1.
3 Don’t ask me how the ministry views 2 driving or other work I wouldn’t want to bet the farm on it.But time spent on 2 is extra time that could have counted towards break between turn arounds and thereby means a longer shift overall or possibly running out of driving time depending on how the ministry man sees it.

WTF??
No-one is talking about “off road driving”
The assertion made (by you) was that time with engine running while building air pressure might be counted as Driving Time. This is complete and utter hogwash. But coming from you I expect nothing less.
3 Don’t ask me how the ministry views 2 driving or other work I wouldn’t want to bet the farm on it.But time spent on 2 is extra time that could have counted towards break between turn arounds and thereby means a longer shift overall or possibly running out of driving time depending on how the ministry man sees it.
If the shifts are planned so tightly that 30 seconds knocking the tractor unit air pressure down, followed by another 30 seconds bringing it back up will cause a problem, they’re unrealistic in the first place. You could easily lose that messing around gobbing on palms to make them seal or doing any number of other minor things, after all…Getting caught by a few red lights…Getting delayed because the automatic gate sticks on your way out…Needing an extra wee mid-journey…etc etc etc

So, not you then.
Oh simply loving the idea of carrying around 4 palm coupling adapters to save time. Which one are you going to connect first? and the rest in what order?

Not just me and never once in almost 15 years pumped the air out of the unit to connect the lines with or without palms or taps.Would probably have been laughed at if ever did.

To be fair I wasn’t referring to using adapters in that case might as well mess around with dealing with the recalcitrant C couplings.
