Critical Stone Crusher Mantle Swap Operation: Safety Challenges & Engineering Solutions

In this video, we address a critical issue in modern techniques for lifting the mantle from the shaft. The current method involves welding two metal plates with holes onto the large and thick mantle, then using chains and a forklift to lift it off. This process is hazardous due to the significant thickness difference between the parts, making proper welding challenging.
Many workers worldwide have suffered injuries or fatalities when these welds fail, causing the mantle to crush those underneath. You can see the small plates already attached to the mantle at 16:16 in the video.
Our bachelor thesis in Mechanical Engineering from Chalmers University of Technology offers insights into this issue and proposes a safer solution. You can find our work here: studentarbeten.chalmers.se/pub....
Although the text is in Swedish, the proposed solution is still accessible and worth a look.

No dust mask, no work platform, no safety harness to name just a few safety breaches

[@nategilman5899]

walking under a boom....

[@stoddern]

Lots of negative comments about safety. Given that Sweden not only has it's own safety administration MYNAK, it also has to abide by EU-OSHA. I think they are just fine.

[@smartypants5036]

What was missing was the team of woman getting paid 77 cents on the dollar doing the same work.

[@khloebarajas7132]

[@stoddern]

OSHA? Did you hear any English, no you didn't. So why would the United States safety administration have to do with anything?

[@sonyopattanaik3983]

Doing fully unsafe work, no safety harness used during height work.

[@williamclements3266]

NO MASKS?????

[@AKAtheA]

pointless hi-vis vest? Check
pointless helmet? Check
A way to safely stand atop the crusher to actually do his job? nope, too expensive...
corpo "safety" in action

[@TheBFBomber]

And no breathing mask...
