I disagree, Excel is faster and easier, once you get used to it.
the deciding factor being what components the plant buys.
at most outages using Excel, they do not buy enough different types of Excel components, which then requires us to use Pole/Knuckle in combination with Excel....and even then its faster than brand, or straight Pole/Knuckle. Ask any tech that has crawled up on a 60 foot Excel scaffold nd they will tell you they felt safer than Pole/Knuckle, it is the only scaffolding that the manufacturer will allow builders to tie off to while erecting.
It is also considered medium-duty, we use it for any rigging below 1000lbs using swivels and a 3 pole triangle set-up.
A single 5 ft TR5 Excel truss will hold 3000lbs
Excel is also the only scaffold OSHA will allow to be built and hoisted to the work location.
As you can tell i like Excel. Talk to anyone that does Byron outages, 85% of the scaffolding is Excel....but remember it is faster, we generally build 400 scaffold in a week. Excel will shorten outages.
