Can't Slide Tandems, Pins Won't Retract
Topic 22263 | Page 1
Is the linkage disconnected from that larger arm on the right side? If so, then I think that's the problem.
Stupidly enough, I pulled out of the parking spot and out to the front of the property cause maintenance isn't allowed inside, as soon as he shows up and I pull the handle, the pins retract like normal... What the hell! Were they so rusted that the potholes I hit on the way out broke them free? 3h of my day wasted, now I have to go through Memphis during rush hour...
Guessing the frame was askew.
I move tandems sometimes 4x in one day. I always use the Johnson Bar (jockey brake) to hold them as opposed to the spring brake (parking). I rock the trailer once or twice and the pins have always released. Many times when pulling the pin lock, they'll stick. Rocking the trailer slightly, forward then reverse will release them. I've (knock-on-wood) never had to resort to assaulting them with a mini-sledge.
Hope that helps.
Tandems:
Tandem Axles
A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

TWIC:
Transportation Worker Identification Credential
Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.
Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.

I did try that multiple times. It got to the point where I was just dragging the trailer forward and back. My guess is it was just sitting too long exposed to the elements causing the mechanism to rust stuck and hitting the major potholes miraculously broke it loose.

Haha... the proper name for that tool is "A bit of encouragement." A full sledge is "encouragement." :)
Usage: I had to use a bit of encouragement on the malfunctioning computer. I fixed it so nobody can fix it!

Makes sense...now we all know the reason why you are trying to become a truck driver...
Sometimes the bolts that attach the pins to the piston that retracts the pins comes loose or breaks. 1/4 20 × 2" bolts will fix the problem.

I recommend you carry a spray can of good quality penetrating oil on your truck. WD-40 works for a lot of applications, but penetrating oil would be better for rusted tandem pins. I don't use it often, so a can lasts for years as long as it doesn't ever freeze.

Been there, done that. I have one trailer that never seems to want to release the tandem pins. Sometimes requires some momentum and Johnson bar. When it sounds like something has seriously broken, that's when you know you can get out and retract the pins. Naturally, this is my employer's trailer of choice when delivering to the dock I have to move the tandems on every time. 🤣
