Wheel chocks

They would work for a stubborn slider on a trailer whose spring brakes would not hold sufficiently. But for these situations, a 4 x 4 post (ask a flatbed to borrow one) will usually help give the weak brakes some additional holding power to keep the trailer tandems from rolling as you're trying to slide.

If you're not using air-actuater slide system, and using a pull-rod system and using trailer service brake to hold, and they still roll, you for sure need to use some other blocking means to keep from tearing up brake shoes, or you have a bunch of brakes seriously out of adjustment.

However, if the tires are being skidded already (spring brakes holding), then these would be useless and you need to consider other options such as 4x4 post, big rocks, or curb or whatever else you can scrounge up.

 

Last time my spread axle would not open up (flatbed) Ive asked shipper to ley me hook up chain to his forklift (they usually have tow hook on the back ) and then he yanked it open with his forklift.

 

Those look more like a parking brake for an electric brake trailer to me.

 

Go with the Texan and spray the slider down with a water hose. Rubber chalks do not tend to slide on the asphalt as 4x4's sometimes do. Can sometimes use the curb if you are back sliding, sliding while backing. Make sure all the pins are released.

 

boy that would make a mess if you forgot it and tried to drive off!!

 

LMAO! That's genius!

 

Those ones on Amazon are for a camper! I have a set......NO way they would hold 22.5 trailer tires....CRUNCH!

 

Be cheaper to buy a 4by4 dunnage. 8 feet long. if you can't find a free one. Cut in 2 foot sections. Then cut diagonally. That'll give you 8 peices of angled chocking wood. 2 per tires. Front and rear.

6by6 might be better though. And home depot or Lowes don't charge for the cutting.
