Nice. Didn't mention lifting the legs back up a smidge off the ground to ensure easier recoupling and catching the kingpin.
Hi,
With modern tractor units, you can drop the suspension to get under the trailer without damaging the mudguards and raise it back up again, taking the legs off of the floor as it shows in the video, allowing the 5th wheel to be in complete contact with the underside of the trailer. This ensures that you never miss the pin.
In the 'Good Old Days' before hydraulic suspension, it was advisable to drop the trailer with the legs a couple of inches off of the floor to ensure that when you picked up the trailer you didn't miss the pin. Thank god for hydraulic suspension. You don't need to do this anymore, nor do you need to rub away the top of the mudguard in the process.
Thank you 😊
That last 3 point getting off 😂. He wasn’t sure which foot to lead coming down 😂. Nevertheless simple 👍
Spot on
I'm pretty new at driving with trailers.
When I'm dropping a trailer off I do these things in order:
1. Apply trailer parking brake (red button)
2. Open up the fifth wheel
3. Uncouple all cables
4. Raising the truck a bit, raising it to max if it is front heavy
5. Lowering trailer legs
6. Lowering the truck
7. Drive away
I notice that when I'm lowering the truck sometimes it seem to be some tension still, even though the fifth wheel is opened. And sometimes I hear a bang and then it releases so I can drive off.
Is this something bad and wrong?
No one has said anything when I've asked.
Maybe I should drive forward just a bit and then lower before driving out completely?
Just be careful if you move forward with the trailer legs down, as you will damage the trailer legs. Other than that, I would say you're doing pretty good.
@@deepfiix Thanks for the answer. I've actually started to drive forward just a couple of centimeters before lowering the truck, no tension this time. I also lowering the legs until they touch the ground and then just raise them a centimeter or so, so that I gently lowering the trailer on the legs
My dads a driver I’m not and it’s amazing how I know how to do this lol
Did I miss when you get out of the cab switch your engine off and apply your brake.
No trailer parking brakes applied Lol
The trailer parking brake is applied on each and every occassion that the trailer is dropped. This is the first action that the driver takes. It shows this action clearly on the video and also in the written instructions that follow the clearly shown action.
The written version also appears: 'You must always apply your trailer brake, even if the trailer has an automatic brake, to be on the safe side'.
You would be surprised at how many drivers think that the parking brake is automatic on all trailers, so don't bother to put it on.
