Lifting a GIANT Trailer in Seconds, These Jacks are SWEET!

This is an awesome way to put a massive trailer up for servicing.

You ever wonder how they change tires and brakes on a massive trailer like this? Well, they use a specially designed drive on jack that also has a jack stand all in one. It’s like a lever and when the truck backs up over them it gets catapulted into the air on top of the jacks, and to get down it just has to pull forward it’s a really cool concept and works great.

Trailer Breaks Free and Goes Head on at a Car!
