Having installed many concrete anchors over the years this caution would concern me.

Each MaxJax™ lifting system is supplied with ten drop-in anchors and ten 5/8" x 2" high-yield hex bolts. The holding power of the anchors depends on the quality of the concrete and where the anchors are placed. If the concrete is old and brittle, the holding power of the fasteners will be reduced. Likewise, if an anchor is placed too close to the edge of the concrete or too close together, force generated by the anchor may break the concrete. The recommendation is that anchors should be placed no closer than 4-1/2" from the edge of the concrete or other anchors.

Further installation requirements?

I also noticed that the demo cars are small and looking at the arms for the
lifting it appears that the steel is a bit thin. So without passing judgement
I wonder if it could lift my 6000Lb beast on a regular basis let alone what the continued
effect of installing and removing the pillars over time would cause to the concrete anchors without using epoxy.
