ABSTRACT:
A worker platform assembly is modular in construction so as to be configurable according to the configuration and size, particularly width, requirements of each bridge and to metal surfaces thereof which are to be reconditioned by abrasive stripping and recoating. The assembled platform is suspendable at each end by suspension frame assemblies which are rollable along the parapets of the bridge for repositioning the platform assembly, with the suspension assembly being adjustable to various configurations of parapets. An adjustable curtain frame enables sealed enclosure of bridge surfaces to be treated and optimum access of workers to those surfaces during the treatment. Airborne residue is evacuated by vacuum for subsequent disposal in a manner which does not contaminate the environment, while heavier residue and spent abrasive grit is collected and positively moved off of the platform assembly for subsequent, environmentally safe separation and reconstitution of the grit for reuse.
