Does each lift have to have a load test every year?

Once every five years in Canada.

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

Ohhh she'll pass...

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.

I think I've seen it before somewhere, not sure if it was here though.

Yeah...that is the Eskimo Rollback Test done at Winter Park. It is already on the site and was popular topic in July and August.

I'd like to see the Eskimo Express go through that...

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.
