How long are the lifting forks (15” for lifting flotation tires or 22” to raise both dual rear tires)?
A 12” long fork won’t fully engage a floatation tire and certainly won’t grab both rear tires. Mohawk Lifts lifting forks are able to raise both dual rear tires.
The first image shows a Mohawk Lift with lifting forks lifting both dual rear tires. The 2nd image is a Rotary lift. The third image is a Steril Koni Lift.
