I heard couple stories recently from climbers who are questioning safety climbs on towers. One lost his life due to a device malfunction the climber was using provided by his employer. This particular device has fallen into scrutiny in the UK and Europe for malfunctions that have resulted in other fatal injuries. The device had a tendency to roll out which resulted in this fall. I haven't been able to get very intricate detail yet because the case is still in litigation and the person sharing this with me was trying to be careful. The second climber was slightly injured when the safety climb cable worked out of the stand-off at the top of the monopole. From what the climber was told, the cable tends to twist out of the grab device sometimes. I rarely trusted safety climbs to work from as a positioning device myself, but on some poles I would use it to hang dish mounts, boom mounts, and running lines. I have seen as many as three to four climbers working off the same safety climb device on monopoles (I don't know why, but I saw it with my own eyes in total disbelief). That caused me to question whether that was safe or not, since the device to fall into compliance would need to hold 15-20,000lbs. Is this correct to assume? I don't climb anymore but these stories got me thinking about how trusting I have been with these devices in the past. I know they tend to loosen (especially on poles that have slip-joints). It only takes a minute to tighten a loose climb up. Has anyone here had a problem or heard of problems like these?
