Weak links in chainsaw lanyards (EN)
31m
Do these products provide what they promise?
Chainsaw drops provide a connection between the climber's harness and the chainsaw. They are designed to keep the saw from falling off, but also feature a predetermined breaking point so that the strap will break if the load is too heavy.
Strops from various market-leading manufacturers are tested here to find out at what load application the strops fail and whether the products actually deliver what the manufacturers promise:
That the saw will not drop under a lesser degree of loading, but that the lanyard will break off (or a fall-damper trigger) if too large loads are applied.
