The Fresh Aero
EasyLift 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 Fresh
Aero EasyLift
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 EasyLift 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
the lift points specified in Grumman maintenance manuals (station
125). This is very useful for strut servicing too.
Innovative features include:
Six ton heavy duty hydraulic jack coupled to a
robust welded steel support structure with a 17 inch square 11
gauge base to enhance stability
Support structure is heavily powder coated with
a durable and attractive finish. This coating looks great and will
last a lifetime.
An articulating support 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. Lifts the aircraft
at the locations specified in the Grumman manuals for excellent
access when performing strut, wheel or tire maintenance.
The support beam features a
structural aluminum "C" channel core fastened to a treated wood
sub plate and cushioned with a heavy duty wrap around carpet. The beam extends the width of
the aircraft with a large load lifting area – considerably more
than required by Grumman service manuals.
The support beam ram socket
is designed to locate the ram end (and pivot point) as close to
the aircraft as possible. This increases the overall stability of the
lift.
1 ¼ inch diameter ram with a 1 inch diameter
Acme threaded screw and nut for adjusting the crossbeam height
prior to lifting.
Balanced heavy duty carrying handle for easy
transporting and handling
Locking collar on ram for additional safety
Tool holder for jack pump handles and locking
collar wrench is integrated with base for easy and quick access
to tooling
No assembly required! Just drop the Acme
adjustment screw into the extension ram and you’re ready to lift
– right out of box!

The
Fresh Aero EasyLift 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 EasyLift one of
the finest lifting systems in the aviation market today and a superior
solution for lifting Grumman AA1 & AA5 series aircraft. It
doesn't get any easier than this!
Notes:
We manufacture the EasyLift 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.
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 10 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.
Shipping Costs:
We ship the EasyLift in two containers, a 18x18x20 inch box that
holds the Easy Lift's base, jack and brace structure, and a 4x6x48
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 adds to the material and labor
costs. The EasyLift can be shipped UPS Ground or USPS Parcel
Post and we have included a shipping estimator on our shopping cart
for your convenience. We
have considered fabricating the EasyLift 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 EasyLifts 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 EasyLift up in person (see
note at bottom of page).

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
Fresh Aero 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 EasyLift 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
EasyLift 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
