I am 72 and the physics of that were covered in 9th grade which was a long time ago. You could of course place a couple safety stands in the middle of the spans and the numbers improve dramatically. I am surprised BendPak does not offer something of that sort as an option.Sorry if this is an overpost but I just want users to understand that:
YOU CANNOT LIFT A L2501 SAFELY ON A 9,000 LBS RATED 4 POST CAR LIFT
The safe lifting capacity on a 4 post lift is based on having 4 wheels at or near the lifting posts, as the vehicle being lifted has a smaller wheelbase the safe lifting capacity of a 4 post lift falls dramatically.
See this specification sheet from Bendpak:
View attachment 94715
K is the runway length, towards the bottom is the "Min Wheelbase at Capacity", all of these lifts are rated for 9,000 lbs. Below this is the "Min Wheelbase @ xx %", these numbers show how the safe capacity of the lift reduces with wheel base reductions, these capacity reductions are very eye opening!
A Kubota L2501 HST without loader, no loaded tires and probably no fuel weighs 2,623 lbs acording to the Kubota data sheet and has a wheelbase of 63.3". None of the 9,000 lb 4 post lifts detailed above, that are designed to lift a car or truck is safely capable of lifting a bare non loader Kubota L2501.
As the wheelbase falls below 70" or 80" all of these lifts are below 25% capacity rating of 2,250 lbs. At 63" wheelbase a bare L2501 is an unsafe load and could result in lift / runway failure. The runway is stronger and provides more safe lift capacity the closer you are to the 4 posts.
I'm not singling out Bendpak in any way, it's just that they publish the data clearly, many lift manufacturers and sellers do not clearly publish or share this data. Many sales people of 4 posts lift do not even know about this fact that capacity diminishes with wheelbase reduction.
Think twice before putting your compact tractor on a 4 post car lift. If you are buying a 4 post lift you need to review if it is suitable for the range of cars that you will put on that lift. A 9,000 lb lift that will safely lift an F150 pick-up may not lift a small Mercedes 2 seat sports car safely!
Stay safe. I'd hate to drop my tractor of a lift!
I have an asymmetric 2 post lift and fore/aft balance is critical to safe loading. For example the balance point on a V8 4WD extended cab pickup can be hard to accurately determine. Consequently every vehicle that goes up on my lift gets a safety stand in the front and/or rear.
