Protection against falls from heights, anually installed

Individual protection system which provides an anchoring point above workers, installed manually and without the need for a crane thanks to its reduced weight (19 kg), which makes it possible to safely carry out tasks for placing boards, guardrails, safety netting and formwork risers when a crane is not available on site. Significantly increases the protection of workers on site, acting as a complement to collective protection.
