Abstract
An edge protection system including spaced counterweights each having a connecting bracket on one side thereof. Cantilever arms each have vertical legs on opposite ends, with one leg pivotally secured to the counterweights and the other leg secured to hubs. The vertical legs may selectively support the cantilever arm at a height sufficient to allow workers to walk upright beneath the arm. Wedges connect ledger ends to connecting wheels on hub vertical posts, and secure a stiffener to the wheel and ledger sections. Counterweights have a U-shaped bracket and a plurality of weight blocks. The blocks are selectively stacked on the bracket with one upright leg extending through weight block center openings and the other upright leg in side slots of the blocks. A trolley has a carrying connector for connecting to a connector of the one upright leg on top of the counterweight for transporting the counterweight.
