@superwhiteboy78 it sure did shake the 30+ story building, those were the high speed cars, we tested them 3 times and people thought we were having an earth quake. The only thing we broke was a the bracket for the ring n string on the counter weight. Good times. I been laid off since Feb 2010 and am anxious to get back in the shit.
@cquetsch There is a buffer on the pit floor for the counter weight. Once the counter weight lands the car won't travel up anymore. The hoist way is designed for there to be enough room in the the over head for the counter weight to land on the buffer, and in the event that the multiple safety switches designed to electrically shut the hoist motor down fail, the hoist ropes will break traction without the counter weights aid to lift the car, and the car will not be able to travel up any further
Sometimes it damages things in the hoistway. Nothing that isn't able to be repaired. In this case nothing was damaged. We just racked the car a little bit and that is easy to straighten out.
in response to your elevator crash question... No that was not a test tower. We increased the speed of the elevator in an existing building. Which means they needed new rated buffers, and we got to test them.
I did the full load tests at thomas eagleton federal courthouse in st. louis, mo. Those cars go 1200 feet per minute and make some racket on impact

Question for any elevator mechanics who might read this.
There is a buffer to safely stop the cab in the event it impacts the floor of the shaft.
Is it possible to have a malfunction that would cause the cab to impact the top of the shaft?
Is there some sort of buffering mechanism on the top of the shaft ?
Just curious. Thanks.

That was cool... How much weight was in that when it dropped?
radioprankster 3 years ago
fully loaded and running at high speed. If I remember correctly there was 4500 lbs loaded in the car when we crash tested it.

Wow, those buffers stop that elevator quickly!
