Abstract
Abstract A scaffolding platform is provided which is stronger and more resistant to damage. The platform includes two longitudinally-extending parallel rails and transverse, parallel cross rails affixed at least to end portions of the longitudinal rails. Mounting hooks for mounting the platforms on scaffold frames are affixed to end portions of the longitudinal rails by fasteners which are located on both sides of one of the transverse rails for each hook, there preferably being four fasteners for each hook. One end of each of the transverse rails has a notch to straddle the body of one of the mounting hooks between its two pair of fasteners.
