Safety line, for working on scaffolding, is attached to a runner on a rail fixed to the scaffolding frame with a free path to rails on neighboring scaffolding sections

摘要

The safety line (6), for a worker on scaffolding, is attached to a runner (7) on a rail (8) attached to the scaffolding frame (1) to run along it. The rail is structured to form a running track with a neighboring rail for the line at the next scaffolding section (9), with a movable lock at the rail ends. The length of the line is adjusted automatically with the worker's movements, but locks on a sudden pull.
