Power for lifts?

[Automobilist]

We're pouring the slab for a new garage/shop this week. Will be installing two BendPak lifts, one two post & one four post.

Question is: should we run conduit for 220 under the slab, and bring it up right by each lift? Or, should we bring the lift's power in from overhead? I guess we need air lines as well for the safety lock releases, and that will come overhead.

Seems a whole lot easier to go overhead because of the motor elevation on the lift.

A lot easier to come from overhead. Motors are typically mounted near the top of the columns.

When I build my shop soon, I'm planning on running conduit underground. Would love one day to be able to set up a bridge crane, and power coming down would mess that up.

From my point of view as an electrical contractor the more you can get in the slab the better off you will be. A few reasons for this is you can run the conduit as the crow flies. Less conduit and wire. PVC goes in at about 100' in a matter of minutes. As for the point of connection on your lift I am pretty sure it will be about 4' above grade as most lift motors have the control mounted on the motor itself. As for bringing the conduit up in the right location you should have installation directions that will give you all the dimensions you should need.

If i was wiring your garage I would have as much conduit in the slab as I could.

For a 2-post: maybe. You'd want to make sure you get it in the exact right place.

For a 4-post: no. The flexibility to move a4-post around is important.
