'''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.
''Transport belt'' may refer to:

|-
| {{imagelink|express-transport-belt|Express transport belt}} || 5.625 || 7.144 || 40.179 || [[Logistics 3]]
|}
 
==Basic==
'''Task''': make a steady flow of items from your [[Mining drill]]s to the [[Furnace]]s.
 
* 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 belts/Physics|Transport Belt physics]].

===Turns and bends ===
[[Transport belts/Turns|Turns]] will always keep the alignment of items.
 
[[File:transport-belt-two-lines-1.jpg|thumb|256px]]
 
===Belt Lanes: using two sides===
Belts have [[Transport belts/Belt lane|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 belts/Physics|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 [[Transport_belts/Optimizing#Parallel Belts|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 [[Transport belts/Side insert|inserted from the side]] and they stay on the side of the belt they came from.
 
=== Lane Mixer (Mixing both sides of a belt into one) ===
 
Mixing of two lanes into one is depended on the fact, that you cannot really controll, how the mixing with the splitter works:
 
Without usage of underground belts:

With usage of underground belts:
:[[File:Ss+(2015-06-14+at+10.54.34).jpg|300px]]
:[[File:LaneMixer.png|300px]]
 
A third type of mixing is by using the different speeds of the belts. A basic belt as input and put this into an express belt.
 
    vv
    vv
    vv <-- this belt needs to be basic belt!
  >>>>>>>>>>>>
    ^
    | This belt needs to be express belt!
 
  All other belts needs to be fast belts!
 
The result is, that if the output belt is not jammed, then the both input lanes are guaranteed to be mixed 1:1.
