<p>The present invention provides a guardrail system for scaffolding and mobile towers, in particular a guardrail system which facilitates the safe construction of a guardrail about a level of a scaffold construction above the level at which an operator is standing, the guardrail system comprising a frame (12) which is substantially rectangular in shape, a pair of upper couplings (14) and a pair of lower couplings (16) extending from the frame, the couplings being operable to secure the frame between a pair of scaffolding support members by advancing the upper couplings in a first direction into engagement with the pair of support members to define a pivot axis extending between the pair of upper couplings, and rotating the guardrail system, relative to the scaffold, about said pivot axis such that the pair of lower couplings are advanced in a second direction, substantially opposite to the first direction, into engagement with the support members.</p> |
