Tandems are stuck.

Don’t grease the rails. It’ll pick up all sorts of garbage and that grease is terribly sticky. I pull a 2000 and it slides around great. My biggest tip for actually sliding is to spray PB blaster right around and into the friction pad where it touches the slide rail. Usually my biggest problem is getting the pins to go in. You could try (CAREFULLY) to slowly roll forward or back and use the trailer brake to get them to pop loose and start the roll whichever direction you need to go. Also make sure you’re using absolute lowest gear. Lots of people start in 2nd. Make sure you use 1st. Someone else probably has better tips. Good luck.

 

I agree with checking the gear. I had the same problem before I figured that one out. My truck sometimes likes to try starting out in 5th, which is too high to slide tandems and bogs it down. Shift it down to 1st.

 

Start with your tandems slid back roughly to where you think they might be close, before loading. You’re trying to overcome an awful lot of friction/stiction.

If you’re 45K pounds on the tandems, I don’t see how you’d ever get the tandems far enough out from under the weight. That’s 11K pounds over. 11 X 4 (holes per 1K) = ~44 holes. There’s not that much rail available.

 

How about a pic of where you are applying lube... that sounds so wrong

seriously I have seen a trailer that had grease on top of the slide rail.

 

Had one that sprayed grease on the outside of the rail.

I'd check that it isn't pinched somewhere, not that GD ever screws up. LOL

 

I agree it is always easier to slide tandems before you get loaded. In my brief period pulling the awful reefer trailers 2020-2021 there seems to be more and more customers that require trailer tandems be slid to the rear of the trailer before they will load or unload a trailer. I don't know how long that has been going on. I NEVER saw that in my dry van OTR days in the 90s and 2000s. I don't know if that has been common practice for a long time with reefers or not.

 

Doesn't work with air release.
