My client wants to fix a pillar crane to an existing 200mm thick concrete slab containing mesh top and bottom. The crane comes with a 900mm x 900mm base plate with 8 no. 30mm dia bolts around perimeter with an embedment of 385mm, obviously not possible. i have proposed a 2.4m x 2.4m base plate which reduces the forces on the concrete slab and have proposed using M16 HIT-RE 500SD fixings at 250mm centres embedment depth 125mm around the perimeter. Max axial load is 48kN and the overturning moment from the crane is 129kNm. Can you confirm if these fixings would be adequate.
Please call me if required mob 07879171920. Thanks
