Nothing to do with tippers or mixers, but I once took an artic to a nursery (flower and plant type) to load up. Narrow access, but a big field in the distance to turn around. Ground dry and firm.
Tight squeeze between a skip and an old water tank. No problem. 
Entering the field I start to notice big holes that are some part of the drainage system. Not wanting to put a wheel into the nearest one, I ‘turned’ earlier than I would have liked.
The ‘old water tank’ ripped off the height control valve on the trailer. Ah well. Back to the yard, five minutes away, and get another trailer. 
This time. I reversed in. 
Not an easy task with a building on the ‘blind’ side.
Now bear in mind that this was a company that did ‘fridge work’. I was picking up rolling dolly’s of bedding plants. No-one had said to ensure that I had a load bar or straps. Fortunately, I had with me a load strap that I had ‘acquired’ from elsewhere.
2+ hours later, arriving at the destination, which was totally different to the delivery instructions, which I’d established by talking to other drivers, the aroma from the Pansys (the floral type 
) was overpowering.
It is sad reflection on the state of the Industry that companies are so set upon ‘chasing’ a profit that they are willing to send an inadequately equipped vehicle to an unsuitable site just to ‘make a few quid’.
In this instance. I doubt if they did.
