How to trick your Gantries to work (almost) for free

This contraption can extend or contract probably any number of gantries for negligible power. Here, 12 gantries do it for 200 J stored in one small transformer. All extend/contract at once, during that they declare they're out of power but finish the move. Then they again indicate they're powered and are ready to move back.

All that's needed is to hook them all on single wire behind one small transformer. No batteries, but the transformer must not be out of charge.

Do you want gantry unions? Because this is how you get gantry unions.

WE WILL NOT STAND FOR WORKING FOR NO POWER! GANTRIES, UNIONISE! WE GO ON STRIKE!

Nice trick. I ended up removing them entirely since the astronaut going for a pee break after every mission was slowing them down.

I mean, refuelling takes time, so can't be that grievous a time-loss.

Don’t they only leave the capsule if you unassign them?

Sometimes they do, sometimes they don't. I didn't notice any clear pattern yet.

Yeah, I was thinking the same. Could've sworn they stay if assigned.

Gantry is useless anyway , you don t need them. Better have skilled dupes with jet packs . Worst case use gantry to load astro and deconstruct

If it wasn't so strangely shaped I might use it. But it doesn't go all the way to the other side nor does it end perfectly in the middle of the rocket (so you could combine two of them for one rocket). Plus it has 2 tiles at the side.

Interesting. Certainly a neat trick! My guess is that the gantries don't have enough time to switch from "powered speed" to "unpowered speed" before they're finished moving.

For my rockets I have gantries for every... single...segment... because I'm constantly changing components around. I just delay each gantry by a few seconds when they extend or retract by using a buffer/filter combo as to not overload the conductive wire. The bunker doors take 45ish seconds to open anyway so I have plenty of time to spend on extending/retracting the gantries.

Exactly my case.

My bunker doors are controlled both by rocket launch/landing system and by meteor detection so most of the time they're already open when the rocket becomes ready for launch.

Yeah mine too except they stay closed until the rocket is ready to launch, then the green signal from the rocket sets off the whole sequence to launch. Opening the doors, pulling away the gantries, etc. Once everything is open, a green signal is sent to the rocket to launch it.

I like watching the whole sequence sometimes, I think it's fun, It's almost like a countdown in a way, that's why I don't just have the doors open with the rest of the doors when no meteors are falling. Plus it's all automatic so I never actually have to do anything.

Not like they consume a lot of power anyway, a tiny chunk when the rocket comes back to refuel/let the astronaut out, and a tiny chunk when the rocket's about to blast off.

Neat find anyway.

It’s less about power and more about line limits. I have two gantries on my rockets and delay them to avoid overloading the circuit they’re on, if only for a fraction of a second.

If it was a fraction only there wouldn’t be any damage as overload starts to damage only if overloading takes longer than a second.

Gantries take longer than a second to open

1
ohcibi•

Yes but overloading does not. Which is the point of this thread.

Which is a great way to illustrate the difference between Joules (work) and Watts (power).

The gantry moves for 1.7 seconds, consuming 1200 W - that should translate to 2040 J per gantry, 24480 J for twelwe in my case. More than charge of one smart battery.
