Re: Keeping Your Mind on the Job.
I used to work one of them presses, that one has no light curtain which stops it being operated when there's people in the machine. The top of the die is not bolted to the top half of the press so my guess is he was cleaning the top of the die before lowering the press to bolt the die to it and another operator on the other side (normally 2 operators) lowered it to bolt it up. The press can't collapse as they have a safety that rams the press up to it's top height incase of any malfunction. Ps that's a 1200 tonne press. It's about as tall as a 4 story house. |

Re: Keeping Your Mind on the Job.
If you look at the bottom right of the press in pic 1 you can see the bolt holding the die on, there are none in the top. On the right of picture 2 there should be a damper visible at the end of the press so it doesn't shake the factory apart, this shows it was still being setup for a new job. On a side note, when maintenance got sloppy in our place we'd just run the press louder till the MD complained and his office was 3 floors up abour 1/4 mile away.  |

Re: Keeping Your Mind on the Job.
No, there is a speed control but at either end of the scale it is slow. The only explanation for him getting trapped is that the press was raised just high enough to load the die, that is done to save time. Unfortunately in this case it also means it was low enough to trap him as soon as it started moving. People often clean the top of the die of during setup to get rid of the hydraulic oil on it which drips off and onto the operator and floor. The one I worked on was a Rovetta manufactured in the 60's Incidentally, the pit underneath the press is normally as deep as the press is high, I remember ours once had so much oil and water in it it was full to floor level. It took 2 tankers to drain it all. |

Re: Keeping Your Mind on the Job.
One last post, the only accident I've seen on one of them machines before was while loading a 4m by 2m die, the truck slipped while placing the die on the location pins and the die fell off the back. I was round the back when this happened, yes it was brown trousers time. |
