Nope. I don't think I've been there. But it looks pretty daunting. Basically you treat it as a left parallel back?
If you are really having trouble, get some of these or similar. Must be the soft ones: https://www.amazon.com/Agility-Trai...words=soft+orange+cones&qid=1615517140&sr=8-8 Use them to extend the line from where you want to go. All about putting the trailer tandems into the right slot.
Guy hasn't bee here since last March... Anyway, that channel someone mentioned here, seems to be pretty educational... Guy uses a "game" to demonstrate all kinds of scenarios and how to deal with it. Here are some examples of tricky backings... First one someone sent him a video of the dock they need to back into and he uses his "game" to simulate the backing... The name of the channel is My Trucking Skills The game is called "My Trucking Skills - The Game" and is available in the PC version, you can find it on his website. He also offers his email address.
Trying to figure out what I will be doing... Actually, I am in another hotel, in another city in TN.... Taking a few days backing and truck driving refresher classes.. After over 2 yrs out of he truck... today was my first day. Did some backings in an old International, clutch was so hard that I got my leg shaking most of the time... and screw up with concentration... Did drive around in an old 10 speed and in an automatic for the first time.... Didn't like the automatic but that's what companies are using now...
Its something you will pick up with time just keep on doing it and eventually you will become a master just like the rest of us became, well some may still be working on it I guess based on how some people park at truck stops. For example when you park up at night at a truck stop, always if you can reverse park so that way you only have to move forward to get out. Always be aware of your surroundings before you start reversing if not then get out and take another look at large warehouses this usually is not a problem with plenty of turning area in which to get the truck set up the best option is to do as big a loop as possible so you only have to back straight up in between the yellow lines onto the dock, if this is not possible then try and get the truck as straight as possible before backing in, alternatively if your backing in from a parallel position line up the rear of the truck with the yellow guide lines and then do a complete 90 degree turn by swinging your steering right around then following the trailer around. It is rather hard to put this into words and is much easier to show you on the spot unfortunately we're not there to do so. However as they say practice does make perfect, if your not sure just get out and take a look familiarize yourself with the surroundings and be aware of what is around you in tight spots.
Saw a dock today.... Not tight but not very easy either.... Red arrows show entrance. Yellow line shows docking area. Notice yellow poles and other obstacles... Saw a truck backed to that dock... Driver said he did a blind side, jackknifed with rear tandems all the way to front and after a certain point, he turned wheel hard to the right and pulled up, then moved tandems all the way to the rear and finished backing... Would like to have seen that... from above...
Yes make no mistake this company has designed a true obstacle course for truck drivers. This certainly would make life difficult for the best of drivers, my only suggestion to the company is why not redirect traffic on entry to come in from the other end this would make life so much more easy for driver to back into a dock, as usual no thought or consideration what so ever is given to the delivery drivers.
