Edge protection system using cantilevered counterweight

摘要

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.

主权项

1. An edge protection system for protecting workers pursuant to protection codes, regulations, or prudent safe concerns, comprising;
a plurality of spaced counterweights each having a connecting bracket on one side thereof; a plurality of cantilever arms, each of said arms having a first vertical leg on one end, each of said first vertical legs being pivotably secured to one of said connecting brackets for pivoting about a vertical axis of said leg; and a plurality of ledgers having opposite ends; a plurality of hubs, each of said hubs secured to the other end of one of said cantilever arms and including a connector with slots therein connected to one end of each of two ledgers; a stiffener connected to at least one of said two ledgers and connected to one of said hub connectors by a wedge through a selected one of said slots; and second vertical legs on the other end of the cantilever arms, said hubs being secured to said second vertical legs, wherein said first and second vertical legs support the cantilever arm at a height sufficient to allow protected workers to walk upright beneath said arm.
