A logistics tower placeholder with a 16 belt goods elevator, up/down to 4 high for use over buildings. 
Only use the 12 main belts if you plan on replacing it with a tower later!
* belts exit on the opposite sides to entry.

 As the early limit is 150 facilities, I've only posted the kit. 
The 8 basic belts (4 each up & down) may be mixed, matched & rotated into whatever tower you need. :-)
Just remove the belts you don't want with shift, then rotate & paste over it to fill the gaps with the belts you DO want.
The colourful thumbnail is an ALTER'vator made just as noted above. :-) 

* If you have problems with collisions, construct it nearer the equator.
