Abstract

A guard for structural members is disclosed. It can reduce worker injury with a thin sheet metal or plastic, broadly U-shaped guard plate attached to a structural support through attachment to a pair of clamps, each with a primary and a secondary threaded clamp mechanism. The attachment between the guard plate and pair of clamps may be via a slotted intermediate structure. The primary mechanism has a swivel pad end while the secondary clamps have a pointed, cone-shaped end. is the guard can be used in wind turbine towers to protect workers on a fixed ladder from hitting interior flanges as they climb up and as they climb down.
