Arrath posted:On all large construction equipment I've seen it shuts the motor down immediately. They'll probably just bypass the emergency shutoff to get it moved away. It only needs to be moved a quarter of an inch away, and rollers aren't top heavy. A medium length 2x4 would probably provide enough leverage to pry it away from the post and pull the stop button.

Arrath posted:Alternatively, give a mechanic 5 minutes and it'll never happen again! I worked with a pressman who used a magnet to gimmick the safety switch on our Heidelberg 4-color press. He was super-duper proud of the facts that he could open the covers to the rollers while the press was running at full speed (10,000 sheets per hour). Ever seen a press eat someone?

We defeated the magnetic security thing on a big laser cutter to try to laser cut someone's finger nails with the power turned down low. Didn't work out so well, he was fine though.

froward posted:here's how I think of it: You can think of it that way if you want, I'm not the boss of you, but each one of those sentences is really damned wrong.Voltage is electrical potential. The usual analogy is that if you want to think of current as water flowing through a pipe, voltage is like the pump pressure. It's got nothing to do with efficiency of anything. If one Coulomb of charge is accelerated across a one volt potential, it's picked up 1 joule of energy. And impedance of a material is dependent upon the material, it (generally) doesn't change based on the voltage; if you have a 2.5 megaohm resistor, it's going to have 2.5 megaohms of resistance no matter whether you put 1 volt across it or 100,000 volts across it or 1,000,000 volts across it (excepting if you stick enough voltage across it to make it breakdown and turn into a short.) But it does change based upon the *frequency* of the voltage. Current, again, has nothing to do with efficiency, it's just the flow of electric charge: one coulomb per second = 1 amp. Watts are not a measure of actual work done. Watts are a measure of power, which is the *rate* at which work is being done. Actual work done would be joules, not watts.

GotLag posted:Do those emergency stops engage the brakes or do they just cut the power? Will they be able to tow it or will they have to cut that pillar? BEGIN INFOTAINMENT: I can't speak specifically about this roller company, but in general the emergency stops on hydrostatically (hydraulically) controlled equipment like this just shut off all the electrically-controlled valves on the machine or dump pump flow directly to tank and all controls stop working. Typically there are no brakes in the conventional sense on hydrostatic machines; the hydraulic wheel motors provide turning force and stopping power. Often the emergency stops do not kill the engine, since turbo chargers on diesel engines can be costly and break during sudden engine shutdowns, and equipment owners would yell at people for pushing emergency stops, discouraging their use. When you know that emergency stop buttons are just single-pole switches, and you know where they are wired and plugged in, it is easy to TEMPORARILY bypass any damaged or otherwise compromised button. END INFOTAINMENT.

If you open the full resolution up, check out the one at the front-- it actually kinda worries me now that I take a second look Hard to know what there is to worry about : -four layers of shoring material that doesn't look tied together under the mid-outrigger; -shoring material sitting directly on ice; -ice is on sloped concrete; -truck possibly tilted toward its rear so that the part under the crane load is lower than the part behind the crane load (camera angle could be deceptive on this one); -jack at front of truck on at least three layers of shoring material that look to be the same height as its width which is in line with the load; -that front jack appears to be perpendicular to neither the shoring nor the ground plane. Although it looks like if the truck tipped the load would only fall into the building, if they are only lifting in line with the truck body. Nothing to see here, citizen, move along.
