Fallskyddsblock, även kallade SRL, jojo, lina – kärt barn har många namn – är en viktig del av ett personligt fallskyddssystem när du arbetar där det finns risk för fall. Men vad är egentligen skillnaden mellan ett block och en vanlig fall arrester med lina?
How does a fall arrest block work?
A fall arrest block has a wire or strap that automatically rolls in and out of the block housing (much like a car seat belt). In the event of a fall, the block locks in a flash and stops you in a short distance. This reduces the free fall height, which is crucial when working at low heights.
When should you choose blocks instead of fall arrestors?
- In case of limited headroom (you have no room for long braking distances)
- When you want to move freely without dragging excess rope
- In vertical environments such as ladders, masts or towers
- For repetitive work where the rope has to be pulled out and back many times
Tips for choosing a block:
- Check if the block is approved for horizontal use if it is to be used over the edge
- Choose the right length (too short a line limits your movement, too long can be unnecessarily heavy)
