concrete ceiling swing install

im trying to install a swing/heavy bag that can handle about 250-300 lb.
i have a concrete ceiling. its about 2.5" to 3" thick, then its hollow after that.
i was gonna install wedge anchors but im not sure i can do that anymore.
how can i install my swing in the ceiling.

Toggle bolts would be my suggestion if it is really reinforced concrete but the thickness leaves to think it may not be real concrete.

try moving the hole 3" to avoid the rebar,,, the ceiling may be a hollow precast conc plank,,, wedge anchors usually list pullout strengths on the package,,, shear strength would be found on the co's w/site

Keep in mind that a swing involves a dynamic load, instead of just a static load. Meaning you want to use a product that can withstand moving forces.

Do you not have access to the other side ceiling? What about anchoring to a rebar intersection. That's how our chandeliers are hung (a figure eight type loop with one end in the light box and the other around a piece of rebar) granted its not a dynamic load but we have a one in that weight range.
