Gantry treefram brief

The most reliable contraption available in the current version is the crane (other useful ones cannot be used)

### How it works

A series of tree planting and tree chopping work in one direction by a crane with a mechanical hand and a mechanical saw

#### Optimization Ideas

Establish a timeline with the planting of saplings as the origin, the saplings grow until the trees are chopped as the end of time

Shorten this timeline as much as possible to improve efficiency

Can save stress by reducing non-essential blocks in contraptions

### Structural Design Ideas

#### One-piece

Simultaneous planting and chopping of trees by a set of (axle) cranes moving with all the working parts of an entire tree farm

But it needs a lot of linkage blocks so it's not the first choice, but it only needs one axis so it can save the material of the crane

Since it is one piece, if the growing tree cannot be chopped off in time, it will waste the time for the sapling to grow

#### split type

Multiple sets of (axle) cranes moving with a small number of working parts Tree planting and tree felling are done separately

#### Comprehensive

Multiple sets of (axle) cranes move with a small number of working parts Simultaneous tree planting and tree chopping

### Powertrain

The power source of the power machinery in TWR must be a set of steam engine system fuel consumption is indispensable

If the output of the tree farm is used as fuel, the net output of the tree farm will be very small, and the efficiency will be low

The output of the tree farm can be converted into a series of fuels through the fuel processing system, so that the fuel value of the fuel output of the tree farm is higher than the fuel value consumed

Under such circumstances, the power system of the tree farm has completed an internal fuel cycle, so it no longer needs external fuel input and can continue to run

### Control System

①In order for the working group to work continuously, we need to control the direction of movement of the working group so that the working group can move continuously within the working range. A control system is essential

The direction of movement of the crane is related to the direction of rotation of the crane rod, so we can indirectly control the direction of axial movement of the crane by reversing the gearbox

When the working group reaches one end of the crane pole, a redstone signal is sent to change the state of the reverse gear box through the redstone circuit, so that the axial movement direction of the working group changes

(The specific measure is to use a certain method to send a redstone pulse when reaching a certain end to change the state of the latch at the reverse gear box)

②The two cranes drive each other, and the crane rods rotate in reverse. When one crane reaches the end of its movement, the other crane reaches its starting point.

It is possible to move the two crane blocks back and forth in the axial direction

### Optimization Ideas

① Establish a timeline starting from the planting of saplings. The saplings grow until the trees are felled as the end of time. Shorten this timeline as much as possible to improve efficiency

②The stress can be saved by reducing the non-essential blocks of the working group (necessary blocks: the main block of the motion mechanism, the working block, and the storage block). The saved stress can drive additional working groups
