Mezzanine gate assembly
View Patent ↗A mezzanine gate assembly is adapted to provide ingress and egress to an elevated platform while safely preventing falls and injury to workers positioned thereon or even below the mezzanine platform. The mezzanine assembly generally includes a support assembly which has a first and second upright support members. Each of the first and second upright support members has a base portion fixedly attached to the elevated platform and an upper portion which is configured to function as a post adjacent to the respective terminating railing. The mezzanine gate assembly comprises an interior gate assembly and an exterior gate assembly. Generally, each of the interior and exterior gate assemblies are designed to move and pivot through a path of motion which provides a plurality of points of travel. The interior gate assembly is operably designed to engage with and deviate rearward while the load is delivered to the platform via forklift in order to provide a barrier between the respective railing and side of the load. The exterior gate assembly is operably designed to provide a barrier while the load of goods is manually removed from the pallet.
