I thought the last thing you needed was to have the chain slip pulling your fingers into the gear sprocket, amputating the ends of 2 fingers.
At least that's what the elevator repairman was yelling when it happened.
Ouch!
I know.
Sometimes the place I work at is a riot.
It might have warped my sense of humor a little though.
The guy was working on the freight elevator.
The outer doors are horizontal instead of vertical (like a passenger elevator)
The door had cocked slightly, one side higher than the other. So it wouldn't move.
The chain for the door came off the sprocket.
The repairman was pulling on the chain, trying to get it on the sprocket when the door shifted.
The door leveled, once it leveled it's full weight pulled his fingers between the chain and the sprocket.
He shoulda used a bar or screwdriver.
Anyway, I show up to either help, or get a good story, and the guy's yelling "THIS IS THE LAST THING I NEEDED TODAY!"
I wanted to laugh and ask him "Well, WHEN THE HELL DO YOU NEED THIS?"
But, I figured he'd had a bad enough day.
And I was kinda busy trying to stop him from bleeding all over me.
