I forgot to mention blain.de.
I also thought I would share this. We just picked up a Otis 20NICL 2 speed AC 3500# capacity traction machine. We went to perform the 5 year full load test. Now when I pick up something new on service and we are testing, we like to prove it will perform. We started with 1500#. Then we added 500#. The car stalled failed to lift the weight while leveling in. Now the fun begins...
We first found an overload tripped. The dashpot on the N-301 overload relay was low on oil. We added oil and started again. Again the car stalled when trying to to lift 2000#. We removed the weight and ran the car. What we found was that M & N relays were not picking up. The gap was too much for M to pull in. And the coil was bad on N. Now the car operates fine and passes with flying colors.
My point is, I agree with proving the elevator will perform.
