Thanks for the input Tom. May not be overloading it but as for experience? How does that go "what goes up must come down".
Haven't taken the time to call them yet, need to find out if they have a show room, want to see it before I bring it home.
The one thing that concerns me is the size of the base plate where it bolts to the floor. With this type of hoist, verses the ones that have a beam across the top, all the load is transferred to the concrete anchors.
A friend had this style hoist, but a LOT more expensive installed in his small shop. Mind he regularly lifts 3/4 ton pickups. The anchors pulled loose on his. The company said it was the concrete so he chiselled out the floor and poured a block where the hoist sits. They came loose again, the manufacturer then made the base plate larger but never gusseted it. The plate flexed and the anchors came loose again. On the last go around they epoxied the anchors into the concrete and the problem seems to have gone away.
I have 6 inch thick floor with high strength concrete (forget the compressive strength right now) with fibreglass chop. So the base should be good. But I do have radiant heat pipes to avoid.
Just did a rough calculation.
For a 4000 pound vehicle if the frame is 4 feet wide the load would transfer about 5000 pounds pull to the outside anchors. They have 3 across the outside so about 1700 pound per anchor. Is that a reasonable tension on a 3/4 inch anchor?

Free advice is worth exactly what you payed for it.
