Abstract

The invention relates to a safety net (10) installable as an aerial rock fall arrestor, which includes a first set of major elongate tensile elements (12) arranged in a major grid with the major tensile elements extending in at least two transverse directions (12.1, 12.2) having major crossovers where the major tensile elements cross each other and defining major grid mesh openings (14), between the major tensile elements. The safety net also includes a catchment zone (16) defined on a main portion of the major grid and an adjustment arrangement extending along at least two borders of the catchment zone, the adjustment arrangement having major grid mesh openings (14.2) that are narrower transverse to an adjustment direction than the major grid mesh openings (14.1) of the catchment zone.
