What type Aircraft have PDUs [Power driven units] to move cargo containers/Pallets on the Freighters main deck.
I've worked on B737 & B757 freighter both which use Manual Manpower to move the Loads to & From the Main Deck.

How is it on the MD11s,B747s & A300s

The Bulk Cargo compartment has the "Magic Carpet"

Hi Mel
The 747F, BCF, CF, and GATXF are the only ones I've worked with full length floors.
The magic carpet is a retrofit made by a couple of companies, the biggest being a Swedish/Danish company.
There are also a few PDU equipped Main Cargo Door area floor kits that you can install quite easily over the seat rails. They allow the cargo to be more easily moved into and out of the aircraft and spun once it's in the door or going out. I've had DC-10's, MD-11's and 747's with these.

IIRC UPS A300s and (MD-11s?) were loaded manually. The 300 was difficult because the cargo floor sloped down towards the nose. The only powered ones I saw out there were the 747s, and I was not trained to operate the system.


When in doubt, one B pump off

For the MD-11, PDU's are an option. LH Cargo uses them, but e.g. UPS relies on system "Armstrong" to move the pallets. The 747 classic PDU's were a pain in the neck, always broken, so we had to explain to the loaders that we would just put them on the deferred items list, because we needed the short ground time to fix other, more important, problems (though the loaders didn't see that e.g. a flight control problem was more important than fixing the loading system for ramper's convinience  Wink ).

Purely from experience, I don't have the weights in front of me, but I would say the Smart Wheels (8 installed) come in at about 50lbs and the Dumb Wheels (a whole lot installed) at around 25lbs.

Now before you ask, a Dumb Wheel works only on one axis, fore/aft. The Smart Wheels, installed in the side door positions and the 2 positions forward (total 4) of the door, will drive fore/aft, laterally, at 45 deg or they'll just drop out of the way as required for a particular load. Great system when it works. Lots of micro switches that go bad due to the area they're in.

I'm sure there would be lifting Actuators for these PDUs,to cater to u/s.

No, there are not. You lug them up the stairs and then lug them down the stairs. Unless, of course, there is a loader on the aircraft with an operator. Then the job is just a bit easier. You still hump them in and out of the hole.

What do you mean? The wheels in the floor convey the containers/pallets throughout the aircraft. The main control is just inside the door (aft) with local controls at various station throughout the main deck. The locals control the individual wheels they are responsible for.

There seems to be some confusion.
Lets rephrase....Are these PDUs Hydraulically driven or these rollers.
