In the U.S., new or relocated installations are required to go through an Acceptance Test with 110% of design load.
For existing installations, they are required to go through Dynamic Testing every seven years, which only requires 100% of design load.

Dino, In your travels, have you found that most lifts are dynamic tested at 100% or 110%? I have heard that some are tested at 110% to get comparable results to the acceptance test.

vt's 7-year dynamic testing uses 110% of design load, have since 1982. all lift components are designed for 110%, no problems other than apu's that used to pass sometimes have run out of steam, or whatever. a tune-up usually does the trick. if an insurance/fed forest inspector requires an "official" procedure, we simply take the loaded portion out of the original designer's acceptance test. the 110% load gives the area some level of comfort that his apu has the 'nads to pull the load when needed.

I have found that most areas are doing the 100% (even though a lot of smaller, remote areas are behind the curve in regards to B77-1999). Many areas with "older lifts" do not have the original acceptance test documentation or a copy of the standard to which the installation was originally tested.
The reasoning for 110% to get comparable data makes good sense. Especially for a lift that is in the 10-20 year old range. MHO

While on the subject of load testing, I wish to congratulate the engineers, technicians and fabricators at Doppelmayr - Cetec on a job very well done. We completed our load tests and final inspections today on two new lifts. I could not find a rough edge. They are both machines that are very well executed - from top to bottom.
Thanks guys, I sold you short - but will not do it again.

I don't know if this video has been posted here before, but today I found this load test video very interesting.

That lift has alot of sag in the cable. The only lift I've seen that had that was a '88 Riblet triple, Sliver Fir at Ski Acres.
You think thats alot of sag? Just look at the Mystery Peek double hall on seymour. On a busy day with people coming out of the cafe (LOL) you can get a 30 ft difference (I think its more) from the returning chairs. It would be amazing to be a lifty riding down.
