Rotary Platforms

A rotary dairy cow milking platform which rotates about a rotational axis, said platform comprising a plurality of pre-fabricated moulded bail floor defining modular components and a supporting substructure, wherein the modular components are detachable from the substructure and each has been:

• a) pre-formed independently of any components comprising or depending from the substructure, and
• b) totally or at least in part formed from a fibre reinforced resin based composite material,
• wherein each of said modular components has a mould defined rigid exoskeleton wrapped about an inlay or an imbedded core of another material moulded within the exoskeleton, each of said modular components having end peripheries substantially radially aligned with respect to the axis of rotation of the milking platform, the modular components having been assembled onto the substructure to form a substantially annular deck of the milking platform, and wherein:
• the composite material comprises fibreglass or other fibre reinforced plastics, or a polymeric system;
• and
• d) each modular component provides at least part of a floor for a plurality of cow milking bails.
