Jim, a semi-pneumatic tire is a relatively conventional tire filled with
(usually polyurethane) foam, so it exhibits most of the qualities of a
pneumatic tire while being nearly puncture-proof.
I just looked up "solid pneumatic" as it applies to forklift tires. Ig
wasn't incorrect, nor using the term differently.
It refers to SOLID tires mounted on pneumatic rims that have (supposedly)
the same compression and flex characteristics of the same-sized pneumatic
tires (for that application), but which - being solid - are totally-
immune to punctures.
They are solid, but made of soft rubber inside, so they act like
pneumatic tires and provide better cushioning. In forklifts, "Solid
Tires" refer to hard rubber tires that are only suitable for use on
hard surfaces. Solid pneumatic tires can drive on compacted dirt. (not
on fresh soil)
Is that exactly it or are they foam filled penumatics? I had a scissor lift
at one time that had tires that looked like they belonged on an ATV. They
were heavy ply pneumatics that had been foam filled. It worked well on hard
pack and decently on turf. They would get torn up rather quickly on asphalt
or concrete, so I had a second set of the regular white rubber hard tires I
used most of the time.
I paid $400.00 for my new to me 1971 vintage 4000 pound capacity
propane fueled AC forklift. I decided to see how high the forks would
go and amazingly they go up 15 feet! I was shocked. My building is 17
feet inside so it could be used to place stuff in the loft. Cool.
Well, that didn't take long to "pretty up". But you better drive it long
enough to rub all that yellow paint off the tires! <G>
Good deal, Ig. If you weren't so far from me, I'd make you an offer. My
little forklift just doesn't hack it for some of the jobs I need to do.
