After digging around, I've found out about spring balancers. They sound like the thing I've been looking for (see previous log) in that they're a tether used to counterbalance tools to prevent strain on workers. The cool feature is that the balance force is adjustable, which is even better than a constant force or gas spring strategy. It also requires much less effort on my part to implement.
- The cheapest I found, coming in at £68 total for 8 (4 per SecSavr) delivered and with UK VAT added.
- Might be unsuitable since I can't find the length of the cord, and it's smaller than the other two, implying that the cord is shorter.
- 1.4m cord
- 1.5m cord
- This is the one I'm likely going to go with.
I'm thinking that it might be possible to connect the cord ends together for SecSavr installations that have a Z height that exceeds the cord length of a single spring balance.
