Containerized 757s?

Wed Jan 07, 2004 9:16 am

Not talking about upper-deck igloo-configured 57s.... but more along the lines of any configured with the lower-deck LD3-45s, something like what is offered on A320s?

I used to work at Canadi>n a long while ago, which had containerized A320s with LD3-45s, and just wondering if the 757 was offered with this option as well....

I doubt it. The 757 doors aren't set up for it. If you look at the A320 series doors, you'll see that the door assembly opens so the mechanisms are flush with the ceiling. The 757 does not do this.

It's been a while since I've opened an 757 door, but I recall both opening outward in a similar fashion. I remember the 57 pit being slightly higher than the 320, but that might be my memory failing me  Smile

I don't believe that the belly of the B757 can be containerised. The B757 fuselage cross section is the same as the B737, which leaves little room to economically install a container/pallet system.

No, the cargo bins on a 75 are worlds larger. Wider and taller. But the hinges of the door would be in the way. THey don't open flush with the ceiling.

Its been along time since I turn wrenches for DAL, but I believe the forward pit had a motorized baggage system. There were nesting modules. When the pit was empty, and I believe it was the aft end of the fwd pit, The modules were all up by the threshold, when the 1st module was filled you hit a button and moved it aft exposing the second module, and so on until the area was full.

Any DAL bag smashers or mechs out there?

Don't know about DAL, but BA has a similar system (holds 2 and 3). The purpose was to have the hold filled volume wise, so the load couldn't shift. After a while they found the was a safety problem. Nowadays, the "sleds" have to be fully extended before takeoff. The reason was that the fire-extinuishers are of no or limited use if the sleds are not fully extended.

Boeing did offer the B757 with a cargo container option - no airline ever took it up. The containerised option had 7 LD-W containers in the fwd hold, and 6 LD-W containers in the rear hold.

I'm lead to believe that Northwest almost did take this option on their 757s to ensure speedy turnarounds, but backed out at a late stage due to technical concerns.

I know Boeing also offered containerised cargo holds on the B727-200. Not the -100 though, since their cargo doors open inwards like the B737. I've seen photos of TWA B727-200s having containers loaded, and this photo of an Eastern B727 from 1977 shows they also used the system. Take a look at the enlarged version...

I'm off to see if I can find some more examples...

Seems American Airlines also did it, although the only photo showing it wasn't very clear. Still, it at least shows Airbus weren't the first to containerise the belly holds of a narrowbody...

I wish UA's 727 had that. All of our 727-200 had nesting systems up front. Our 757 and 320's have them upfront and in the rear.

In my opinnion the A320 hold is a bit higher than in 757 and also the doors on A320 are wider. Finnair has on its 757s a moving "mat" in the compartment 3. The bags are loaded over the mat and when the row is full the mat is being moved a little bit forward with a control panel in the hold. I like this system, because the comp. 3 is so long and it takes time load the plane. With this system you can wait for the bags at the aft door and load them from the door. It would have been easier to load/unload a 757 with LD3s, but I'm satisfied with this system.

Wilcharl,

I saw this document serie from BBC called "Airport". It's about LHR and they one showed the unloading of Icelandair's 757-300. I didn't notice any moving mat in the hold, but I did notice that the hold 3 was full of backage and cargo. Thumbs up to those guys who load and unload the 757-300 without any moving map!  Big thumbs up

Air2gxs,

Are you refering to the telescopic bin system? I did not realise anyone used these on Boeing narrow's.

-------------------------

As for the sliding carpet - great idea until it stops working. Being hi-friction means picking up and moving bags as opposed to sliding them on the floor of a standard bulk-load hold.

-------------------------

Finnair MD-11,

Your "opinion" on the A320 hold size is correct. The hold on the Airbus narrow's is 120mm higher, and 140mm wider at the base than the Boeing narrows. However, the Airbus narrow's have flat side walls which reduce the width at the hold ceiling by 420mm compared to Boeing. Whether this is actually usable space in the Boeing hold is another story....

UA has them on all their 757's and A320's. All of our 727-222's had them also. Its great, you never have to leave the door area. I rather work a bulked out 757 over a 737-300 anyday. It less work with the 757.
