Introducing the Steelebrook
Easy Lift System for Grumman AA1 & AA5 Series Aircraft
|
|
|
When
it comes to lifting Grumman AA1 & AA5 aircraft, special
requirements are needed to assure safe and damage free lifting.
For nose gear, wheel and tire servicing, current Grumman AA1
& AA5 series aircraft lifting procedures include placing sand bags or other weight on the top
surface of the horizontal stabilizer to lower the tail section and
consequently raise the nose. Recent evidence suggests that excessive
loading of the horizontal stabilizer has contributed to stabilizer
spar support fatigue and cracking. As a result, an Airworthiness
Directive was issued by the FAA to address this issue.
The Steelebrook Easy Lift
System was developed to completely eliminate loading the tail
section and correctly places the lifting load precisely where
Grumman maintenance manuals specify – at station 51, just aft of
the firewall on AA1 & AA5 series aircraft.
The Easy Lift System can
also be used to lift each main gear and wheel assembly without
loading the strut. The load is spread out almost 4 feet along
hard points specified in Grumman maintenance manuals (station
125). This is very useful for strut servicing too.
Innovative features include:
Heavy steel support braces captured in a wide sturdy steel base
for excellent stability
Welded support structure
Robust 1 1/8 inch diameter jack column
An articulating lifting beam that mates perfectly with the
bottom of the aircraft and pivots to compensate for the increasing
angle of incidence as the aircraft is raised
The crossbeam features a
structural aluminum "C" channel core with a treated wood
base covered with cushioned fabric. The beam extends the width of
the aircraft with a large load lifting area – considerably more
than required by Grumman service manuals.
The crossbeam ram socket
is designed to locate the ram end (and pivot point) as close to
the aircraft as possible to increase the overall stability of the
lift.
A safety pin backup provides 2 tier support and redundancy.
No assembly required!

| The
Steelebrook Easy Lift System provides a stable and safe lifting environment for
servicing Grumman AA1 & AA5 series aircraft gear and wheel assemblies. A combination of
innovation, quality and intrinsic safety make the Easy Lift one of
the finest lifting systems in the aviation market today and a superior
solution for lifting Grumman AA1 & AA5 series aircraft. With
proper handling and operation, this jack unit will provide many
years of reliable and safe service.
Note:
We manufacture the Easy lift System in Tennessee and normally
have one in stock. If we are back ordered, the wait time is about 2 weeks. Please call or email us for wait time
and other info.
Shipping Costs:
We ship the Easy lift in two containers, a 20x20x20 inch box that
holds the Easy Lift's base, jack and brace structure, and a 4x7x48
inch container that holds the crossbeam components. Shipping
weight is about 58 pounds for both containers. A wood inner
frame is built into the "base" box to properly support the
system during transit. This ads to the material and labor
costs. The Easy Lift is shipped UPS Ground . We
have considered fabricating the Easy Lift as a disassembled system
for less expensive shipping but wanted make this unit as rigid as
possible and eliminate any assembly on your part. We
wish we could get our Easy Lifts to our customers at a better price
but this is about the best we can do at this time. To avoid shipping costs,
you might want to consider picking an Easy Lift up in person (see
note at bottom of page).
Note: UPS rates are a little better for us now and we're
passing that savings on to you. Calculate
your current shipping costs.

Steelebrook Easy
Lift System -
For both Grumman AA1 or AA5
series, nose & main gears (ram inserts included) - $249.
Additional Notes:
Metal prices have increased significantly this year
and we needed to increase our Easy Lift prices slightly to absorb
some of this cost. Thank you for understanding.
We put a lot of work into
packing these lifts so If
you're visiting the Nashville area, please consider flying
(or driving) into the Lewisburg, TN
(LUG) Airport for an Easy Lift demonstration. If you purchase
one, we'll knock off 20 dollars and you'll save the shipping costs
too -- 30 to 80 dollars. Please call ahead to make sure we have one ready
for you.

The
Other Side of Wide
Remember
the “Wider is Better” commercials on TV a while back? I believe they were touting the virtues of wide wheel base
vehicles and how wide platforms were always better from a stability
perspective.
This
is right on the money because wide supporting platforms do substantially
increase the overall stability of objects like the vehicles in the above scenario.
The
Steelebrook Easy Lift uses wide platforms at the base and crossbeam to
increase the overall stability but there is another side of wide – the
spreading of the lifting load out across a large area to greatly reduce
load concentrations.
You
see this applied everywhere in manmade and natural creations. Consider how snowshoes spread the weight of a person’s body
over a large area to prevent sinking into the snow.
You can try this yourself by standing in snow or mud with just
boots and then laying down a piece of wood and standing on it. The wood spreads the load out over a larger area and “sink
rate” diminishes proportionately.
Now
consider the Easy Lift crossbeam and how it mates with the bottom of the
Grumman AA5 aircraft. The
load to be lifted at Station 51, the nose wheel lifting location, is
approximately 550 pounds, give or take for fuel, engine and other weight
factors.
The
Easy Lift crossbeam makes contact with the aircraft with 253.5 square
inches (42.5” x 6”). If
the total load is 550 pounds, one square inch carries only a little over 2
pounds (253.5 / 550)! The
Easy Lift spreads this weight out so there are absolutely no load
concentrations at the point of lift.
Each square inch of supported aircraft only carries about 2 pounds –
well within the design parameters of the Grumman AA5 Series aircraft.
The AA1 Series aircraft fairs even better because of its lighter
weight.
For
you tech types, we know there is a very slight beam deflection
factor that will load the the aircraft closest to the ram a little more
then migrate out with a slightly lighter load towards the ends of the
crossbeam. This is really very minor and certainly hundreds of times
better the concentrating the load in a small area. Yes,
wider certainly is better! Bob
