摘要：
A fall prevention safety device for the head-carrying carriage of drilling machines, includes a safety cable constrained between the carriage (C) and a rotating drum suitable for winding the safety cable. The drum rotates according to the translation of the head-carrying carriage in such a way as to maintain the safety cable constantly tight, so that when the drive chain is no longer tight, the safety cable holds the carriage and prevents it from falling down.
