And then when we introduce slack on a belay device down the bottom at a bottom anchor, it runs through this pulley and the load travels down this skate block line, effectively working like a track line. The skate block, you’re probably familiar with its operation, but the great thing about it is we have our load applied to this pulley and it’s the weight of the load, which is tensioning the system. Again, it’s not new, but it’s something we need to discuss and get out there into wider use a bit more. But the question, which is quite valid, that’s come back to us is, “That’s great, but it’s complicated and it needs a team of more than what we often have.” So, we want to introduce the mirrored skate block. By that, I’m thinking about communications tower workers and crane workers who are often just the crane operator and a dogman who may be caught in this situation where they have to effect a rescue from the jib.ĭifferent times when we’ve taught skate block rescues, we’ve tried different techniques introducing fore and aft belays to protect the system in case we have a failure of the main line. Skate blocks is something that we’ve taught for many years, and often struggled with presenting various components of them to different teams, particularly small teams working in remote areas. Today, we want to have a look at skate blocks.
