Gantry crane

[jPRO93]

Hey guys!

Having problem to attach crane (1x1 wheels) on 1x1 small block platform (track).. Idea is have wheels on top and under that 1x1 platform.. However attach wheels from bottom seems impossible. I would like to avoid pistons, since they gonna be placed in final crane (that will hold hangar miner)

Purpose of this crane is simple, just need precisely put tunnel miner on platform trucks.. Then its job is done. And yes, i know i could just make it much easily, but thats not my way.

On YT i found same concept (just dont want use thrusters as source power), so it HAS to work. Its only about proper attachement way.

I know that you know many useful tricks and would be happy if you could share a bit for me!
Thanks much


(when you just want make hangar hall, but only preparing for first drill takes so much time, but i love it :D)

When i made my train i had to create the wheels so when i opened it up with ride height i could slot it over the track. Then put ride height down again and it would grip the rail.

You probs wont be able to place wheels while the thing is in position, have to build it then move it over (or sideways onto) the rail, then adjust ride height to grip it.

This is all so much easier in creative ofc, just paste it where it needs to be, in survival you will have other issues to overcome like moving it onto the rail with a ship or something :)

Hm... problem seems that i am not suing suspensions, but rotors... It works somehow, but looks dumb, when wheels are only on top...

I try remake with suspensions i think...

Ehm.. yea, this is 7th version, i destroyed almost perfect flat moon surface in front of hangar bcs of this :D

Heres a couple shots of the running gear i made, it might give you some ideas. I think your defo gonna have to use suspensions not rotors for the height adjustments :)

Thats looks pretty cool...

However this is how closest I am...

Ahh yeah just swapping those rotors out for suspension should work great from that screenshot. The problem with rotors is they dont absorb any shock, so itl be prone to exploding or spinning from internal forces. You can see how some are already bent from the weight or tight fitment :)

Exactly, that rotor used to adjust height to add wheel (with rotor part) with another support ship and then attached to rotor, support ship almost didnt survive tho :D ...

Really tried so many ideas...

Now i try completely make bottom on its own and then attach via merge blocks to top part of crane
