Now that everyone’s condemned this bloke, lets break it all down.
First things first, he’s got an audience of at least one driver and an assessor/trainer, presumably watching but not being exactly shall we say helpful.
Obviously he’s never had an auto DAF before cos he didn’t know about the gear selector and its manoeuvering functions, he may never have had the dubious pleasure of ZF’s version of automatic clutched hell before, he may have had a Volvo, he may have had a Scania, both of which are at least able to competently control torque when picking up a heavy.
So he’s now found reverse cos one of the audience has shown him where it is, he’s backing under this trailer then, presumably loaded, knowing how the clutch on these things behave he’s probably reached that point where you have to provide loads more torque to get the thing to push under.
Remember those watchers…now does it need a bit more power to push it in (often with an almighty bang) or has he got it off centre and trying to push against the king pin with one side of the fifth wheel.
So being a sensible sort of chap he’s pulled the parking brake on and got out to have a look see where he is before he does some damage.
Unfortunately with his audience enjoying this, and bearing in mind he’s never had a ZF auto before, certainly not a DAF or MAN anyway, he’s got flustered, who wouldn’t have by then, and forgotten to take it out of gear.
Now as to safety, as he’s being watched at this point, did he put the parking brake on before diving under to have a poke nose?, if he did whats the big deal, if he didn’t then a gentle reminder at that point, or rather a bit of help for a bloke in a new place might have been more productive than the way he was treated.
When you who can do no wrong get another new type of lorry to drive, i hope its in a strange place, with regular full timers milling about watching and waiting (but not helping/instructing) for you to muck up…the you might recall this incident.
