Hollowcore planking support a lift?

[rkaiser58]

Hey guys. I am finally starting my build of a 25X30 garage with a basement. The top level will use hollowcore planks (7) 4'X30'. The question is, I want to put a lift (max weight on the lift 9000 lbs) in one bay on top of the hollow core. Has anyone used this and know if the planks can support the weight or require additional bracing underneath? Also what lift is recommended? 4 post?

Thanks for the help.

call a lift company, talk to them. i bet it can be done, but you may need to upgrade the floor system a bit. maybe pour 4" on top of planks, etc......

id call the concrete company before the lift company, they lift company wont know anything about what the concrete companies panels support. you'll ll probably be beefing up your floor system considerably if you go with a 2 post, id imagine a 4 post will be a better way to go since you are exerting essentially the same force as a car with 4 tires would on the floor and the only issues i see you having are the addional weight of the lift to account for and solid anchoring points for the posts.

you reminded me as i looked at the lift picture that if you plan to use the lift for vehicle storage and parking underneath you should also mention that fact to the concrete company since they need to make sure it will be holding the weight of 2 cars and the lift
