Abstract (en)
[origin: WO2016009323A1] Fall prevention safety device (D) for the head-carrying carriage (C) of drilling machines, comprising a safety cable (F) constrained between said carriage (C) and a rotating drum (T) suitable for winding said safety cable (F). Said drum (T) rotates according to the translation of said head-carrying carriage (C) in such a way as to maintain said safety cable (F) constantly tight, so that when said drive chain is no longer tight said safety cable (F) holds said carriage (C) and prevents it from falling down.
