Absolutely stupid shit. I get it, it’s the most dangerous occupation in the country. The class is just stupid .I had to do the 3 day new miner at red dog mine in bfe ak last week just so I could go outside and measure some plow trucks for a few hours before the plane left on day 4. I now understand your hatred of msha
is it just a bunch of shake hands with danger videos?
Pretty much.
.Mine was 3 days of repetitive shit that could have been condensed into one 8 hour day. Reminded me of HAZWOPER and every boring monthly safety meeting with a sprinkling of actual mine related stuff all rolled into one.

make them deeper
Yeah that is the plan. Just need to find an extra long 1.5” fine thread tap. 2 of the holes are where the retaining pin is so that probably won’t work for those.
next size bigger for those holes?
I forgot to ask if the hoist and traverse functions are all VFD or contactor driven on that crane.It does. Takes a hard job and turns it into a 1 person easy job. Gonna pull a moil out of a surestrike end block tomorrow by myself. Damn block must weigh 4-5000#. Moil is damn near 10” around
I still need to put on a fall protection harness and Superman across the shop on the crane.
Vfds. Just had to replace one last month. It was letting the magic smoke out.
Are your bridge motors 120 hz?
Unsure. I just swapped it out. I thought they were just 60hz maybe not.
Depends as they make both. You can use either, just change the parameter. Obviously both motors should match. I was just curious.
But worse because instead of being produced by people who lived it they're produced by clipboard warriors who screech "written in blood" any time someone questions a policy that was put in place due to a potential hazard they don't understand with technology that's no longer used.
still has exhaust, means it's just a diesel-electric machineThey're coming for yah
As long as the components were engineered to last 30,000hrs I would not be afraid of an electric drive loader.They're coming for yah
"The mine is the world's largest producer of zinc and has the world's largest zinc reserves.[1][2] Red Dog accounts for 10% of the world's zinc production.[3] Red Dog accounted for 55% of the mineral value produced in Alaska in 2008."
You bolt an ugly post to it to tie off too
.
How many hours on it?
How do they like the electric loader? I’m sure it burns a bunch less in fuel.
That's funny considering mechanical drive was cats sales pitch in haul trucks 20 years ago (Electra haul was making diesel electric haul trucks back in the 70s).They're coming for yah
Speaking of VFDs, we replaced a VFD for a 25HP pump this month that lost some smoke in the fall, replacement parts took several months to show up so it ran in bypass mode.
Vulcan Materials is very happy. You are 100% correct on the increase fuel economy.
Helicoils.
