Center Roller / Shelf Feeders - My Hat's Off To You

[Fnix]

I was put in them when I first started and pretty much passed out every time. They use them to test you. I still get a few here and there. I knock them out in under 30 mins now just so I can get the hell out of them.

Your drop frames were
H and L type - 26 footer

W - 28 ft drop frame. what you're probably seeing now. I have not seen an H or L in years. These types were 5 digit numbers starting with a 0. If anyone is still using one I would be interested to know. The last H boxes were numbered in the 260 series.
Single W trailers were numbered between 270000 through 299999

WW - flat floor short trailer rounded corners on the front.

somebody else mentioned the shelves in the new WWS types. I think chicago uses most of these in their lanes.

40 ft drop frames were Z trailers 5 digit trailer number starting with an 8.

When a Z drop got old we often changed their type to an S and used it in the yard at which point a 6 was added in front of the 8.

I know of several drivers years ago,that recieved carrer ending injuries unloading the old drop frame trailers.However they were very good to pull down the highway.They were heavy,with a low center of gravity,which seemed to make them trail real well in double and triple combinations,especialy in the wind.The hydrolic landing gears could be a pain in the rear,when they got bent,or low in fluid.When I firat started driving,they trained us how to jack up the tracter to install tire chains with the hydrolic landing gear.They forgot to mention that you had to be parked on level ground.Some drivers would get stuck on a hill,jack up the tracter with the hydrolic langing gears,then after chaing up,the landing gears would bind,leaving the rear of tracter hanging.The driver would have to call a wrecker to get the tracter on the ground.Made some major embarasing memories for several drivers.

What’s the point in those? You have to set up rollers twice or carry all the boxes on the bottom floor to the belt, neither being very efficient.(I'm talking about the ones with the shelves that fold up like /\ to the side of the trailer)
