The Gantry Carriage is a block that can move structures along Gantry Shafts.
|Gantry Carriage||Any Planks
+ Andesite Casing
|Gantry Shaft||Andesite Alloy
+ Redstone Dust
Place Gantry Shafts along where the Gantry Carriage will move. Apply Rotational power to the shafts to move the Carriage along them, and invert the power to move it back. Inverting the placement of the shafts will invert all movement. Use a Wrench to help change the orientation.
Apply a redstone signal to the shaft to stop the carriage and send power through the Carriage's output.
Gantry Shafts attached to the Carriage's output will move along with them automatically.
