#CMT# #/CMT# The guardrail (2) has a hook (17) engaged around a rod of a frame and a vertical scale and provided at an end of the guardrail. An operating handle (4) with projecting part is articulated towards the end of the guardrail opposite to the hook (17), and hooks (19, 20) are placed on the rod of the frame or vertical scale. A horizontal distance provided between an inner edge of the hook (17) and inner edge of the hooks (19, 20) is greater than a distance provided between exterior of the rod and exterior of a post corresponding to the frame or scale. #CMT#USE : #/CMT# Fixed or rolling scaffolding guardrail. #CMT#ADVANTAGE : #/CMT# The projecting part provided towards the bottom being constituted by the unique handle fold along the upper beam, thus reducing weight of the guardrail and limiting encumbrance for storage and transportation. The handle is fixed on the guardrail by an articulation axis, thus preventing problems to the operator, during a mounting operation of the scaffolding. The guardrail is hooked on the rod, without intervention of the handle. The immobilization of the handle in a folding position permits to manipulate and store the guardrail in a secured manner and avoids the risk, during the installation of the guardrail. The guardrail enables easy mounting by the single person. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective over view of a scaffolding guardrail. 2 : Fixed or rolling scaffolding guardrail 4 : Operating handle 5 : Upper beam 8 : Lower beam 17, 19, 20 : Hooks. |
