US Patent 11598108 Support and levelling device

A levelling structure for levelling a structure having supports for secondary support on fixed footings. A coupling mechanism extends between an access point on the structure and the footings. Adjustment of the coupling member from the structure alters the elevation of the structure and supports together towards or away from the footings. By providing the adjustment from the structure itself, the requirement for elevational adjustment beneath the structure is avoided as well as adjustment against the opposition of the load.
