Wouldn't it have been safer inside the forklift cage? Unless the shelves were full of caustic chemicals, I guess. At least you have some protection over your head.

Cage probably protects from crushing, but not from impalement or flying debris. Looks like the "cage" is just roll bars, rather than a mesh.

That was not a big impact. I hope that only happened because the racking is really really overloaded. My workplace is mostly bulky boxes which the overhead guard would deal with but even then, a piece of broken pallet or racking could skewer straight through it or come in from the side. Best bet might be to jump out and huddle against the side of the forklift. I kind of want to stop wearing my seatbelt now. It's not like our electric stand-up forklifts have them, and the seat is deep so you can't slide out.

The guy that posted it said his company actually made them and put them on all the trucks.

quote:

This is my best guess, but I'm not sure.
They're on blow in insulation trucks. Normally the generator on them would run the blowers. The blowers and generators are hard wired together. I think that if they don't want to run the generator they can back feed it with this with a line from another truck, or the jobsite. However that is pure speculation.

Check out this current controller you can make at home!

If you like this, his homebuilt arc welder project is pretty great, too.

Seems like a reasonable solution to the problem "how do I control the current in my home made arc welder".

I can't imagine that all of that material cost + labor costs is saving you much compared to the $50-100 that a new Variac would cost.

Couldn't you just use a dimmer light switch? Or am I completely off on the amount of power those can handle?

Buying all those those parts new is definitely worse than buying a non suicidal option.

That switch is never supposed to open with current flowing through it, it's used for isolation. Like turning something off then unplugging it.

IIRC the problem is that dimmer switches wreck the... what is it, the AC 'wave pattern'? Light bulbs don't care but more complex tools and appliances can be damaged or have their lifespans cut drastically short by that kind of uncontrolled current.

Slight derail, but I read 'The Black Paradox' last night and that artist seriously has it out for loving with your expectations and scarring your mind. I read most of it like this :suspense:. The only thing I could think of more mind loving than reading his work is that video of the guy that did a swan dive off that pier and split his face open.

A dimmer switch using a triac basically chops up the AC waveform. So you get "chunks" of it instead of the whole sine wave. Imagine one cycle of a waveform. If it fires (gates) at 90 degrees and 270 degrees, you'll get nothing, then the "right half" of the first hump, and then nothing, then the "right half" of the second hump that goes negative. It basically acts as two check valves that can be activated at a certain point on the sine wave.

With a rheostat, you add an additional load in series, so you end up dropping the voltage the load sees. You can also do this with a transformer.

You can do this for smaller induction motors, but if you want to change the speed of a bigger induction motor, you need a drive that takes in 60Hz (or 50Hz for people living in weird countries) and changes the frequency - a variable-frequency drive or VFD. These generally (except cycloconverters) take AC, turn it into DC, then turn it back into AC. Or you can make a motor-generator with a DC motor spinning an AC generator.

Yeah, that's pretty much exactly how you do it to do work on foundations or to add elevation supports for flood prone areas. Being that high I'm going to guess they're adding a lower level to allow storm surges to wash through without wiping out the living area or washing away the house altogether. Say like a carport and storage areas. I know that FEMA charges a 10x premium if your house isn't elevated enough in risk areas. So instead of flood insurance costing you $3600/yr it will cost $36,000/yr.
