jacking on concrete base
jacking on concrete base
(OP)
hello,
what should i be considering in order to jack (lift) 190,000lb of equipment. the base is structural concrete with a lift of grout. the grout is not yet in place.
i have thought that the compressive strength of the grout should equal or better the concrete and that a metal base plate should be placed between the back and the grout. this is in response to concerns over compression and pressure?
Also what would the minimum time for the grout to reach adequate strength be?
I look forward to responses.

RE: jacking on concrete base
Make sure the jack has enough excess lifting capacity and sufficient ram travel to lift the equipment without having to keep shimming the equipment and then resetting the jack.
With the little information you have given, I don't think there is much else to add.
