Santa-2023 gave me this -> wide deck scissors jack [deck size 14.6x9.1]
My question is...
What is the proper way to lift our ~900 lb bikes with a scissors jack?
conversely stated
If you want to cause massive damage to your bike lifting it up - what would you do to ensure damge?
My gut feelings are:
- it must be stupid to put the lift directly on the drain bolts and lift a 900 lb bike by bolt threads.
- it must be stupid to lift the bike directly on the joint-seam of the crankcase.
- is it must be correct so "spread the load" to as much surface area as possible
so that no one part is carring the entire weight.
- It must be wise to limit lifting to just the rear tire or just front tire.
the reason why if you lift just one tire, if you remove that tire the bike stability would be un-changed
but if you lifted both tires, if you remove one bike will be soo off balance it would topple had you not ratchet strapped.
- It must be wise to ratchet strap the bike secure once lifted.
As for how to accomplish the above here is what I did
(seeking advice if the above thoughts are right and if the plans below make sense)
I feel that "no one" has dedicated d-ring anchor bolts on their garage floor
yet we "gotta" ratchet strap our bike to something.
My plan is..
- take a 2'x4' 3/4" plywood sheet slide it between the tires so that it sticks out roughly ~14" on each side of bike
- center the jack on the 2'x4' plywood so weight of bike presses entire plywood into the ground.
- move the entire ply wood to so that jack is directly at the desire lift point.
- place a template block of wood on jack pre-notched so weight of bike is not on any its protusions.
By doing the above the weight of the bike will securing the plywood to the ground
I am planning on 6 flush mount D rings (3 each side of bike)
so that I have ample choices to ratchet strap bike to the ply wood.
for front of bike I can attach to frame but for rear of bike what to people attache to?
I am not convinced that the saddle bag guards are a wise ratchet strap point
but nor am I convinced is the swing arm a wiser choice as it moves.
do Y'all ratchet strap the rear of bike? - and how do you do it?
Here are pics of my scissor jack and the wood template I made.
Basically I used kids sidewalk chalk coated the protrusions and used the jack to press the wood into bike.
If there was chalk anywhere on the board I used a grinder and notched the wood away
repeated this until no matter how much I chaulked the protusions it didn't transfer to the board.
Enclosed are pic of end result...
I am planning to use these heavy-duty D rings as my anchors with the 2'x4' 3/4" plywood
