Triple crown "reefer" units

[Anonymous]

I've been seeing more and more TC refridgerated units, which I guess is VERY good news that the "turn around" time for the whole operation is improving to the point they are taking even more time sensitive loads away from trucks.

I've noticed that there is more space between trailers for these units , to accomodate the reefer unit.

Do these trailers require special bogeys to provide the needed clearance, or is the difference made up in the actual construct of the trailer box?

I wouldn't have thought that special bogies would be ecomomical, and could be a logistical nightmare. It must be the bar that holds the front of the trailer to the bogies is longer.

On teh roadrailer reefers the bar that joins the trailers is 3 ft longer than normal to allow for the reefer unit but inorder to keep the same bar form going into the back of teh truck and putting a hole in the back of said truck the kingpin is only 24 inches from the nose of the actual trailer still makes it fun to hook on to you have to make sure your 5th wheel all the way back to make sure you can hook onto it I used to pull roadrailers every now and then and hated the reefers were the biggest pain in the[censored][censored] I ever had to pull

OK,...thanks...

Not to appear ungratefull, but when you say "bar" I have no idea what you are talking about, but get a mental picture of a third component (in addition to the bogey and the trailer/king pin)

I always just figured the bogeys had a 5th wheel on them, where does the "bar" fit into the equation?

I haven't seen any yet, what do they look like? I'll look for them on the 261 and 262.

I believe the "bar" is the 2"thick tab protuding from the front of the trailers that goes into the slot in the back of the trailer in front and is pinned into place. (Think old link and pin couplers, except the link in this case is solid and doesn't move back and forth.)

I'd call it more like a tongue than a bar...extends from the front of the box and fits into a groove at the rear of the preceding box. That's how the Roadrailers are held together; the bogeys just keep them held up (so the tires are off the rails).

Never thought about the problems this thing would give the truckers, but I can see where too much length in front to the kingpin might be a problem! Are there tractors that can't handle these boxes with the longer bars?

OK! Yeah,...I got it now....I had forgotten about seeing that....thanks[;)]

yeah like any JB hunt since to save money they have fixed %th wheels that only allow a 36 inch deep kingpin setting without the tonuge on the trailer so they can not pull a roadrailer at all
