Hello everyone,

So I am having an issue with my trailer. I have a manual lever to release my tandem pins, but on occasion, the thing will not lift up to release the pins. I’ve tried looking into diagrams online but haven’t gone extensive into the research, wanted to get advice or tips first on what this issue could be, before i start digging into articles.

Thank you.

Tandem:

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".

If it's a bar that you have to lift, get two large black bungies from truck stop. Stretch as tight as you can from the support beams under the trailer under the handle. Handle must be unlocked. I put one about where the trailer tire closet to me starts, down under the bar and up as far forward as I can stretch it. Then with the trailer breaks engaged rock the trailer hard. I put in reverse, slowly press the gas, as the rear of the trailer rises a little, take foot off gas and let it come forward hard. Then get out and check. Once or twice and it should come out.

When you have a chance get a two foot piece of PVC pipe. 2" diameter is good. That can slip over the bar for some leverage.

Hope that helps. Good luck.

TWIC:

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.

Sometimes the pins get wedged in the rails. The pins may be pushed against the rear edge of the rail. Go through the same motions of moving the tandems forward (use reverse gear) without releasing the lock pins, similar to what you do to release a jammed lock jaw in the fifth wheel.

Also remember the tried and true phrase,

Get a bigger hammer

to bang the pins back in.

Took a bungee, rocked the trailer, and it was ready to go!

Thank you for the advice and help!
