Factorio – 3 to 1 belt balancer

Here is our Factorio tutorial showing how to build a 3 to 1 belt balancer that reduces the number of belts used while drawing an even amount from each incoming belt.

This 3 to 1 belt balancer is particularly useful at train depots, as two of them are sufficient to provide egress for all 6 inserters capable of unloading from one side of a single train car. If you are carrying two items on each belt, each segregated into their own lane, this belt balancer will keep those items separate in the same lanes after they’re combined into 1.

Factorio – 2 to 6 belt balanced splitter

This Factorio tutorial demonstrates how to build a balanced 2 to 6 belt splitter.

This belt balancer is very useful at train depots. Each train car can only be accessed by 6 inserters from each side, so a 1 to 6 or 2 to 6 belt splitter is often needed. This design shows you how to build such a splitter that provides an equal amount of items to each of the outgoing 6 belts. Providing an equal amount ensures that all your inserters are able to work for the same amount of time, decreasing the amount of time your trains have to wait in the depot to be loaded.

Factorio – 2 to 3 belt balanced splitter

This video shows how to split two belts into 3 balanced belts.

This Factorio tutorial demonstrates how to split 2 belts into 3 outgoing belts in a balanced fashion, rather than just leaving a single belt alone while splitting a second 50/50. This technique can be useful for evenly loading buffer chests at a train depot, since a train car can only be reached by 6 inserters per side.
