Abstract
A support structure for a float pan for floating a concrete surface provides an interface between the float pan and a rotating machine. The support structure is characterized by a hub configured for concentric attachment to a rotor, and by a plurality of trusses that extend radially from the hub, each providing a planar contact surface. A mounting plate attaches between each planar contact surface and a top surface of the float pan and is radially adjustable along the planar contact surface. A truss beam structure cross-links the trusses together. A walk-behind or ride-on machine may incorporate the support structure and operate as a dedicated power flotation machine. Under weight of the machine, the planar contact surfaces of the trusses conform the float pan to a desired shape or radius of curvature for optimizing a flotation process.
