I am building a total of 3
wheeled platforms for 3 Costco (Lifetime brand) 8’ x 7.5’ sheds. I will
build a fourth platform for the current 8’x 8’ Keter shed from Costco many
years ago.
The location for these sheds
requires that they be above the paver deck due to rain water drainage.
Currently the shed is on the deck and it creates a dam which floods the
patio during heavy downpours. I
want to be able to occasionally move the shed to clean under it so it
makes sense to put them on wheels.
Shed weight is about 354 lbs.
and i’m estimating that the wheeled platform will weigh about 350 lbs.
probably less once the wood dries out.
Solidworks estimates that the
wood only is 285 lbs.
If the weights hold true I
should have a load capacity limit of about 3000 lbs. which should be more
than enough for the items I intend to potentially store inside.

paver deck

Thia is the paver deck where the
sheds will be located. The water drains to the right rear corner.
Currently there are a couple sheds sitting on the deck in the far right
corner and they acts as a dam to the water during heavy downpours.
Having the sheds on wheeled platforms
will allow the water to drain freely
while keeping the bottom of the shed dry.
The wheels will allow me to move the
sheds occasionally during cleanups and to seal the pavers when necessary.

Here
you can see the standing water and the slot drain at the end of the deck.
When this photo was taken there was an obstruction in the drain outlet slowing
the water drainage?

Eye bolts installed on the front of the deck to
facilitate moving the shed.
Additional 2” thick blocking was milled and installed
but not shown in these photos. This facilitates the screw schedule for
the interior field.
Liquid Nails Subfloor construction adhesive was used
to seal the edges of the plywood as well as providing additional strength
for the floor sheeting.

Used the router and
flush trim bit to cut out the wheel well openings. Sure beat using the
jigsaw and transferring all of the measurements!

residence within the wood framing and devouring the wood pulp!

Measured deflection without sheeting screwed down
using ~500 lb. point load is about 1/8 inch while bouncing up and down.

Once we finished building the platform, installing the
shed and loading ~500 lbs. of “Stuff” into the shed, Tyoer
and I stood in the opening of the shed while Arlene measured the
deflection of the front support wheel beam. Total movement was less than
1/16 “.
We also stood on the right side and bounced and the
movement was less than 1/8”
While these measured deflections are higher than the
computer simulations, the shed platform is very manly to say the least!
Will be interesting to see how difficult it will be to
move the shed once its fully loaded!
