A load equalizing pier for a coach comprises a stand for placement on the ground and a head for placement under a load, e.g. a coach beam. The stand includes means for adjusting the height of the head. The head includes a base plate for attachment to the top of the stand and a support plate for placement under the load. Springs, supported by the base plate bias the support plate toward a biased position separated from the base plate. Bolts retain the support plate to the base plate above the base plate such that the support plate is movable downward from a biased position to a stop position restrained by the base plate. The springs apply a biasing force less than the desired load such that said support plate, under desired load, is restrained from further downward movement by said base plate. Preferably, the springs apply a biasing force of less than half of the desired load.
