Transport belts are items which are used to transport items from one place to another. There are three types of transport belts, each with their own properties.
Types
| Type | Speed (tiles per Game-second) | Required technologies |
|---|---|---|
 |
1.875 | none |
| |
3.75 | Logistics 2 |
| |
5.625 | Logistics 3 |
Basic
Task: make a steady flow of items from your Mining drills to the Furnaces.
- Select a belt by taking a Storages/Stack from your Inventory
- Rotate the belt by pressing "R" until it faces the right direction.
- Place the belt (by default left mouse)
- Move in the direction you want the belt to go, and hold down the left mouse button: the belt continues to be placed.
In-place-replacement
If you have placed a belt in the wrong direction you don't need to dismantle it.
- Make sure your game-hand is empty and then simply press 'R' over the piece and it will change on the spot.
- This in-place-replacement is also possible with other belt-types. Pick up a faster belt type and place it over the current: The belt is picked up and replaced with that in your hand.
- Many more things can be in-place-replaced: Poles, Chests, Inserters, Assemblies, Furnaces...
Advanced
- For a more advanced introduction into the belt mechanics see the Belt transport system page.
- For information about the finer aspects of handling belts try the page on Transport Belt physics.
Turns and bends
Turns will always keep the alignment of items. Be aware; the inner side of the turn moves items at half the speed, meaning turns are likely to be bottlenecks. Using faster belts at the bend is recommended to maintain capacity of your network.
Belt Lanes: using two sides
Belts have two lanes that can be used for transporting. This allows for either a double flow of one material, or with some careful setup, transporting two different materials on the same belt.
Speed, Density and Throughput: About finding the bottlenecks
This is a mistake often made - even by advanced players. But first we need to introduce some definitions:
- Speed
- How fast does a belt move. This influences of course the throughput. The speed is easy to calculate: Basic transport belt is the slowest, the Fast transport belt is twice as fast as the basic and the Express transport belt is 3x the speed of basic.
- Density
- How tight are the items put on the belts. See Transport belts/Optimizing for tips, how to keep the density as tight as possible. See Transport belts/Physics about how dense you can put the items on the belts.
- Throughput
- This is speed * density. The maximum density on all belts are nearly equal (indeed the density on faster belts is lower, see Transport Belt physics).
This formula
Throughput = Speed * density
gives you two opportunities to enhance the throughput:
- More speed
- more density.
More speed is expensive (see optimizing with parallel belts), so more density is in many cases much easier to obtain. The way is in most cases, to find the bottleneck.
The bottleneck can be seen quite easy, if there is a part of a belt, where the items sometimes stop or don't move (or don't move fast) at maximum density and suddenly they come to a point, where this "stop and go" releases itself and they run free and are not so tight on the belt. This is in most cases the exact place, where you need to optimize your belts. It doesn't make sense to optimize much before or after this point, because if you fix it, you will find the next bottleneck anywhere else.
Side inserts (Crossings)
When belts join together at a t-junction, items are inserted from the side and they stay on the side of the belt they came from.
