8110 - Unimog - MODs and Improvements

[Paul B Technic]

I tried it before at an event and ran into problems with the PTO M-motor overheating and shutting down. It was 15 minutes on and 5 minutes to cool down. The Unimog PTO drive train should be redesign to have less friction if you plan to run it all day. I also had problems with the CV joint popping out. Definitely needs a more direct straight drive line.

Funny you say that, I ran in to the issue of needing to shut down the M-motor while building / testing the loading conveyor, I thought I had killed it at one point, I am tempted to "upgrade" to the L-motor and see what difference it makes.

@Paul B-I think a better name for that last attachtment is a cultivator, not a plow

@dr spock-I don't think they ever considered someone running it all day

Thanks for the suggestion ;)

I have only noticed it with the loading conveyor.

Might have to try make an NZ army style one of these:

No problem

Unimog Attachment - Scissor Lift

Over the past couple of weeks I have been designing and building a LEGO Technic scissor lift. This started off as a standalone project which was going to be separate to my Unimog attachments with manual control. After some early design work and overcoming some issues with both the lifting mechanism and control I designed to instead build this as a attachment for the Unimog, mounting it to the rear tray and using the rear PTO to raise and lower this.

I have spent around 15 hours over the past couple of weeks undertaking the research, design and construction process. I am very pleased with the end result and this is now my favorite attachment.

Unimog Attachment - Road Roller MK2

I have recently redesigned and rebuilt a road roller attachment for my Unimog U400. This is a redesign and rebuild of what I built a few years ago, it fits in well with the "civil services" theme of some of my other Unimog attachments. While researching this I had the goal of using a LA to raise and lower this, I also wanted it to be much more "professional" looking as far as the design and colours went.

Over the past week I have spent some time on this when and as I have been able to, last night I made the final changes and took some photos and a video of it.

Features are:

- Lift and carry of roller (rear PTO / small LA)

- swivel point for steering

Finally I got my 8110.

What type of modification of the basic design are recommend, something about steering, right?

Mine is "stock" except for the motor being replaced with the L motor.

Unimog Attachment - Loading Conveyor

Back in early March I shared my Unimog loading conveyor attachment. I have recently spent some time making some changes to this attachment, the loading area now has a cage around it to allow more parts to be stacked up for loading, new photos and a video are below.

Same for mine so far.

Hi all, after some time watching videos of unimogs in the agricultural industry, i thought it would be nice to make a 3 point hitch like device, and after some experiments i made a good one, it is made to be easily attached to the vehicle, it also has the same shape of the hitching point of the unimog and the PTO, so it can hold the same attachments:

The LDD model:

And the real (ugly) model:

It is able to hold the attachments:

The winch:

And the crane:

The complete lifting movement is about 5,5 studs:

As you can see, it has an small inclination, it is visible with small attachments (like the winch), but with heavy ones (like the crane), the weight of the attachment will bend it and it will be completely horizontal:

EDIT: i have started to upload images from bricksafe so i can make them smaller, thanks for the tip Jim.

Unimog Attachment - Cherry Picker (Aerial Bucket)

Over the past few weeks I have been working on another Unimog attachment, this is a Cherry Picker (Aerial Bucket) which mounts to the rear of LEGO Technic set 8110.

A couple of years ago I designed and built an "Off Road Unimog Aerial Bucket Truck", a video of this can be seen here:

Based on my experience for this I decided to try and build a suitable attachment for the Unimog.

Below are some photos of the end result, it features:

- Lifting of the bucket / arm: This is by the black handle on the side of the turn table. This drives via two gears the large LA.

- Rotation of the bucket / arm: This is driven off the rear PTO via three gears to the turn table.

- Manual lowering of the stabilizers: These are need to keep it level when it is rotating.

I spent a lot on time on getting the arm to raise and lower how I wanted, to achieve the maximum lifting height while still lowering down to roof height for transporting. I had originally wanted to have the stabilizers lowered via a small LA on each side but found this didn't work how I wanted so I went back to having this as a manual function.

Overall I am very happy with how this has turned out.

That is really nice Paul, it looks just like a real unimog, i am now imagining the outriggers with 42043 gear racks, it would look amazing, but it already seems really good.

[Paul B Technic]

Thanks for the feedback.

I am already working on a design for my next attachment :)

[Imanol BB]

i have designed a new cab, it has the same spaces for the IR receivers and M motor as my previous version, but this one has 3 seats, the holes in the roof are now closed and also has a new design, has working doors and the whole cab is 2 studs wider:

Over the past couple of weeks I have been researching, designing and building another LEGO Technic Unimog attachment, this is a flail mower. A few years ago I watched my local council mowing along a creek using one of these and thought it would make a good attachment, it is only now that I have the right pieces to make it possible.

For those who don't know what a flail mower is, below in red is some information from Wikipedia.

"Flail mower - From Wikipedia, the free encyclopedia

A flail mower is a type of powered garden/agricultural equipment, which is used to deal with heavier grass/scrub which a normal lawn mower could not cope with. Some smaller models are self-powered, but many are PTO driven implements, which can attach to the three-point hitches found on the rear of most tractors. This type of mower is best used to provide a rough cut to taller grass where contact with loose debris may be possible such as roadsides.

The flail mower gets its name from the use of "flails" attached to its rotating horizontal drum (also called tube, rotor, or axle). Many implement companies also refer to the flails as knives or blades. The rows of flails are usually staggered to provide a complete cut. The flails are attached to the drum using chain links or brackets, depending on the manufacturer. The rotating drum is perpendicular to the axis of the tractor. The PTO driveshaft along the tractor's axis must make a right angle through the use of a gearbox in order to transfer its rotational energy to the drum. As the drum rotates, centrifugal force pushes the flails outward.[1]

Standard flails are shaped like an extruded "T" or "Y" and the chain attaches to the bottom. There are also proprietary flails with different shapes for shredding larger brush and others that leave a smooth, finish cut.

If a flail strikes an immovable object, it simply bounces off. Other rotary type mowers have a tendency to grab and throw the object out of the mower deck if its small enough. This fact makes the flail mower best suited for areas where thrown objects would cause damage.

Flail mowers may also be used in a more or less upright position for trimming the sides of hedges. They are often called hedge cutters (or sometimes also hedge trimmers) then. Especially in forestry (agroforestry) some very robust variants of flail mowers – called flail mulchers, flail shredders, or flail choppers – are used."

Over the past couple of weeks I have been researching, designing and building this. I wanted this to have two features, the lifting of the how mowing attachment and the turning of the flails, to do this using just the single front PTO I have built a two way switch box, this allows both functions to work off a single PTO. Most of my time working on this has been on the mowing part, getting the gearing right and adjusting the height to ensure it is low enough to mow without hitting the ground too much.

Overall I am very happy with how this has turned out, it works as I want it to and is something a bit different. It is also another "front" attachment which is something I have not built many of and brings with it a number of design and construction challenges which are different to those faced when building "rear" attachments.

Thank you, I really enjoyed building this...

I have been working on a new crane for the mog, and after watching some cranes of palfinger, i decided to make an epsilon, at the first time, i was going to put the 8258 crane, but i thought it was too small for it, so i changed it a bit, the lower part is almost the same, but the upper part is completely different, and because i failed a lot of times trying to make a fully working and compact system to be the same as the Z folding system that has the epsilon, i used Efferman´s design ( http://www.eurobricks.com/forum/index.php?showtopic=57372&st=50#entry1203710 ), and i put it in the upper part, with some modifications, a really basic boom extention system and a small graber, here is the pic and the LDD file:

The crane has 4 large linear actuators, and the new turntable, i will make the base for it later.

I hope you like it.

[Paul B Technic]

That is a good looking crane.

[Imanol BB]

Thanks Paul, i also saw your mower, and instantly i thought in the MULAG mowers, it looks really good with those chain parts and it goes really fast, just like a real one.
