Cartop Sheave in Machine Room
by on 12/08/10 04:03 AM
Here are some images of an elevator's cartop sheave that went through the machine room floor. Were not really sure how this happened or what the circumstances were that could have caused so much damage. Notice how the shackles are pulled into the cartop sheave. This must have been a hell of a ride!

There is no way the machine crushed the cwt frame and buffer and had enough inertia to send the car that high at normal speed. That is a reduced stroke buffer so is prob <500 ft/min car. I'm guessing the brake picked and the low line circuit was jumped out causing it to free fall because the EP generator couldn't output enough current. what controls drive that 155ht machine? Guess that's why we do our emergency tests to find crazy stuff like this.
