the dolly need to have mud flaps on it and light.when pulling behind a single trail hook up the air lines so you'll have brakes on the dolly.you have to hook the rear air lines to dummy glad hands or hook them together.Beeman said:How many have pulled a jiff on the road either behind just the tractor or just 1 pup and a jiff? What's the legalities of this?, and or what's the proper way if there is such a thing?
on od's Dolly's their are two dummy glad hands attached just in front of the 5 th wheel and there should be a place to plug the pig tail into to give you lights.i done it a few times but that was three years ago OD might have changed there Dolly's by now.Beeman said:I know how Roadway installs their jiff-lox into the tractor for transport. Very obvious when you see a tandem tractor with mud flaps behind each axle.
Jiffs also have no license plate and no registration. Pulling behind tractor there is obviously no place to hook air lines and jiff blocks tractors rear lights which causes no brake lights or turn signals.
I am not sure about the license plate or registration. I will look the next time I hook up to one during my PTI. But they do have a annual DOT inspection sticker on them. And the break lights and turn signals on the tractor are blocked by the jiff lock. But the jiff lock lights are on and working. There is still the required lights on the rear of the vehicle.Beeman said:I know how Roadway installs their jiff-lox into the tractor for transport.

Shoot, you better not turn them valves on to that dollie,that sucker will lock up with minimal pressure applied to the brakes.hook the glad hands up but do not turn the vavles on.brutus said:the dolly need to have mud flaps on it and light.when pulling behind a single trail hook up the air lines so you'll have brakes on the dolly.you have to hook the rear air lines to dummy glad hands or hook them together.

There is a pintle hook in the frame of the tractor which the jiff lock hooks to. We also hook the air lines which would usually go to the lead pup in the frame area of the tractor and also a light cord plug. And the lines which go to the rear pup hook up to the jiff lock. When finished the jiff lock has power and breaks as required by law.
Beeman said:I wonder what the legalities of this are. If you pull the jiff behind the tractor the air lines and light cord don't have anything to hook to, the jiff blocks the tractor tail lights. The jiff also has no license plate and I've never seen a registration for one, many have no mud flaps.
