Identify This GSE.

Wed Jul 20, 2011 11:48 am



Noticed a Ground support equipment used by Fedex looked like a Tow bar with heavy weights on Two of the Four sides.
Anyone aware of its usage.

I work with the FedEx in GFK, and noticed they indeed used this as a tow bar for pushback on their aircraft. I always believed it was because one would need traction/downward force in the snow/pushing back a heavy airplane.

The more I think about it, they could also connect it to the nose gear during loading and use it to help prevent the plane from tipping back.

It is a funny looking thing, isn't it?

Fedex uses a tether on the nose gear to keep the aircraft secured. (there are a few famous pictures out there of a fedex aircraft on it's tail while loading). I've seen this contraption used when there is not a securing point built into the ramp.

Here at ARN Fedex have one of these that they use on the A310.
It is bolted on the nose gear during loading.
It is not used for pushback.

I've heard that the A300s are somewhat sensitive to weight distribution during loading. I've also seen references to airlines (UPS I think) using tail stands for the same purpose.

Not noticed it being used as pushback out here.

Is that the term used/.

Fedex operates MD11 & A310s out here,so bound to be used on them.

The MD-11 is tailheavy on the ground, requiring strict discipline in loading, or it will tip on it´s tail.
UPS solves this problem by adhering strictly to a loading, unloading and fuelling sequence to make sure that the C of G always stays forward of the main landing gear.
LH Cargo uses ballast pallets, which are going to be loaded into the No. 1 position before unloading the rest of the cargo commences.
Fedex had some incidents with MD-11 aircraft sitting on their tails and decided to hook the nose landing gear to a weighted trolley to prevent the aircraft from tipping over.

Seems to be the most likely reason.But surprisingly personally I've not noticed it being used on the MD11,whenever I've been present there.So is it optional or a company SOP that it be used?.

I was incorrect. That was kind of a WAG on my part.

on the early 747F's there was a nose tiedown option (a couple of pins) and a hydraulic operated hook that snubbed the gear down.. this looks like a portable nose gear weight that has the same function.

Looks more likely to be the case.A sort of heavy weight attatched to the nose to prevent an aft tilt.

At least at the FX hub I work at, all airplanes have to be tethered before on/offload. The exception is the 727, which has a tailstand. There are some gates that don't have hooks in the ground for the tether, thus the weight cart. The cart is removed before the plane is pushed.
I love the smell of jet fuel in the morning...Smells like victory!

Here you can see it being used when the FedEx aircraft used to halt for a long time at Bangalore airport, India.

Nice pics.....So it looks like a long halt requirement for Fedex.
