I don't know how many states that would be legal in.

It's funny you mention "converter" dollies. I don't think UPS has any "converter" dollies, unless the word "converter" is used because it converts a trailer into a wagon.

At Roadway our dollies were all "Jifflox" dollies. We'd call it a "jiff". The dollies were made to double as a tag axle. Most of our single-drive axle tractor frames had an open tail, and a pintle hook in the frame, just ahead of the axle.

The idea was you could pull a set of doubles to the rail yard with a 2-axle tractor, and come back with a 48 or 53 foot trailer and a 3 axle tractor.

What you'd do is back up to the dolly, grab it's chains and shove them inside the frame and hook them to these hooks by the pintle hook. When you tug on the dolly, it straightens it out and lines it up. Then what you do, is you put it in reverse and FLOOR IT and ram that dolly as hard as you ########## can. On your 8th or 9th try, it the pintle ring on the dolly would actually latch into the coupler inside the tractor frame. Then you take the chains off, twist them up to take the slack out, and re-hook them. There were also glad hands inside the frame for the dolly's hoses.

You pull the safety pins out of the tractor's 5th wheel and slide it all the way up against the back of the cab. Then you replace the pins, and slide the dolly's 5th wheel up onto the tractor frame. There were paint marks on the tractor frame telling you where to put the 5th wheel. You'd put the pins in place and go hook up your 48 footer.

It was a pain in the ### though. Yellow didn't have this type of equipment so one time at the Kansas City rail-yard a Yellow driver saw me trying to ram the #### out of the dolly and came over thinking I was insane or something. He had no idea that our Jifflox dollies were made to double as a tag axle on the tractor.

Yeah and they didn't have spring brakes. To make them stay put, you had to have air pressure in it's tank, and pull out this knob that would lock up it's service brakes. We always had to chock their tires because if one of them loses it's air, it would take off and those dollies weigh like 3000 lbs. They'd kill somebody if it ran 'em over.

ive seen a runaway dolly before in our yard....it jumped out of the pintle hook on the tractor (most of them are junk because they only are used to pull dollys around the yard) and the road driver was too lazy to hook even one chain to the tractor......it could have easily killed somebody

If your 10 yr old couch flew out of the back of your truck while going 70 mph down the road.... do you (a) tell the wife the truth, that you didn't tie it down, and now it's a trashed mess.. and honey, we have to buy a new couch... or (b) honey, we stopped at 7-11 for cokes, and two guys stole the couch... and honey, we have to buy a new couch.

Quick story for all to enjoy about couches : Our guy was on a trip and during this trip he broke the company speed limit by 2 mph for 1HR thereby gaining 2 miles. Gets close to the terminal and falls in behind a Saturday mover...moving a couch on the state hwy. Couch falls off pick up and our guy destroys it...had no choice.

Company convenes accident board. 4 drivers, safety and the TM to rule p / np.... drivers vote n/p....TM overrides and votes preventable.

Why?

" If he hadn't been speeding back there then he wouldn't have been here to hit the couch " No sheet.......

The couch incident......

Those jiff loc dollies/tag axles also had an air ride system in order to raise or lower the axle to adjust for weight. Controlled from inside the cab w/ a air gauge which was set around 60psi on the cab gauge. Never had much trouble hooking one up. But did get a ticket once cause the air bleed off and did not see it as I crossed the scales. I must own at least 1/2 mile of interstate from all the tickets over the years.
