The other day we had a Skywest/United Express CRJ700 go tech at the gate, and as we are a very small station and are crunched for stands, we decided we would tow it off the gate and somewhere out of the way. I was told to go get our RJ towbar (we normaly service CRJ200s and everything here is a power/turn out) and the guy incharge couldn't get it to fit. He was nearing the end of his shift so didn't seem to care much, but i went to one of the other airlines to see if they had a towbar from when they used to have -700s but the ferry permit came in very quickly so i never found out. everyone i talked to at the airport seemed to think it should've fit (no one haveing ever pushed or towed a 700)

My Question to you guys... are -100/-200 bars different than -700/-900 bars and if someone had pictures showing the differences that would be great. also, are there any other types that have a different towbar for different varients? (B737-100,-200 vs all the others come to mind)

pics appreciated

Yea, I think they are due to the heavier weight... bigger gear

Not sure about the CRJ.....However I remember the towbar for the CD/IC B732s were of a different attachment [used to clamp to the bolt holes in the lower strut which was used for the cross pin].Where as other airlines had a hook attachment holding that very pin.
This was years ago.

Bingo. The -700 nose gear is wider then the -200. The RJ towbars that we had at DAB had interchangeable heads. The bar itself was identical, but the end that connects to the aircraft could be removed and replaced with the wider (or smaller) one.

ok good to know, and i'll go rooting around to see if i cant find the other head. otherwise its riddiculous that we have -700s and -900s (CRJ705) in and we dont have a tow bar for them.

thanks for the replies

The CRJ200 axle hubs were the bar hooks to the A/C is about 17 5/8 inches wide...
The CRJ700 axle hubs are 18 5/8 wide (both +/- 3/16)

This is a loose approximation because I measured the towbar pins not the axle hubs themselves. There is about 1/4 inch play on each pin end
this is close enough for Gov't work

I don't know about the CRJ900 since we haven't ever gotten one in MLB.

The CRJ-900 uses the same towbar as the CRJ-700



The only valid opinions are those based in facts
