Here's a small preview of our latest project at work. A complete review will follow soon.

Here is a short video in German.

Mini Unimog THW

While being busy at work and university I spent less time building with LEGO^®. I tried to work on some projects like a dumper truck and a street sweeper, but both of them need some more time because of problems in development and lack of time figuring those. So I came up with a THW-Version of my Mini Unimog Fire Brigade.

"THW (Technisches Hilfswerk) is the Federal Agency

for Technical Relief of the Federal Republic of Germany.

Its statutory tasks include the provision of

technical assistance at home and humanitarian aid

abroad."

Source: http://www.thw-nw.de

Its main features are as follows:
- 9V power supply with "generator" and light towers
- Trailer with lifting mechanism
- Boat with raiseable propeller and hatch

And this is what I came out with.

I used a Hinge with Towball Socket (30396) and a Steering Knuckle Arm (6572) to attach the trailer to the Unimog. Therefore, the Hinge is placed inbetween two Axle and Pin Connectors Perpendicular (6536). At the back is the 9V power take off using a Plate 2 x 4 with Contacts (4757) connected to an Electric 9V Battery Box Small (4760c01) via an old Electric Wire (5306b).

The trailer can be lifted to launch the boat, while the winch can pull it out of the water. Both functions use a combination of a Gear 8 Tooth (3647) and an Axle Pin with Friction Ridges (42093).

The boat is also a simple build with hatch at the front to rescue people drowning, a searchlight and a raisable propeller.

One of the various helpful tasks of the THW is to illuminate the deployment location. So it has two light towers using the PF LEDs (61930c01) and a generator to "hide" the wire connectors of the PF LEDs and the PF Extension Wire (60656).

This is my first presentation without real photos due to the lack of some parts (and money) and I would like to get some feedback, if this is an equivalent alternative to photos of the build model.

Note:

LEGO^® Digital Designer lacks in some parts, you have to replace the fake parts of these:

- Electric 9V Battery Box Small (4760c01)
- Electric Wire (5306b)
- Electric Plate 2 x 4 with Contacts (4757)
- PF LEDs (61930c01)
- PF Extension Wire (60656)

Mini Unimog Fire Brigade

After introducing my Mini Version of the LEGO^® Technic 8110, I have to build another Version. A Fire Brigade Truck, inspired by VFracingteam's Unimog.

Its main features are as follows:
- 7-wide, compared to the 9390 axle width
- Live axles with suspension
- Portal axles
- HOG (Hand of God) steering

Fire Brigade Version:
- Front PTO with water cannon
- Water tank and pump

And this is what I came out with.

The Unimog is used in rough terrains and with the snorkel it's able to cross small rivers.

A water cannon lets the firemen extinguish the fire from inside the cab.

The roof contains some tools and the "water pump" which is an old Pneumatic Spring Cylinder (5103). Its main advantage over the new pumps (2797c02) is the ability to suck in the water. 

A Pneumatic Airtank (67c01) is used to store the water.

The pump can be lifted to be operated easily and is stored when not in use.

 

The most important part of the pumping mechanism is the Pneumatic Distribution Block 2 x 4 with Non-return Valve (4692). There is the tank insert on the left, pump in the middle and the water outlet on the right. 

It's a Fire Truck, so it has to be able to extinguish fire. To proof its ability I made a short video.

Note:

I used colored round Plates to show you where to connect the Hoses.

Mini Unimog U400

This is my latest MOC, the probably smallest functional version of the 8110, unlike the cute 9390, which is very limited in functions. The whole MOC based on an older chassis I now finished the last evenings, using LDD again.

Its main features are as follows:
- 7-wide, compared to the 9390 axle width
- 355 Parts
- Live axles with suspension
- Portal axles
- Front and rear PTO with gearbox
- Working winch
- Working crane with a grabber
- Two outriggers
- Tiltable bed
- HOG (Hand of God) steering

And this is what I came out with.

Unfortunately I didn't own that much orange pieces, so I made it Lime Green for the first presentation.

To achieve a live axle setting I used the Liftarm 1 x 2 with Ball Joint Angled (50923) and realized the suspension with Rubber Connectors (45590).

The winch at the Front-PTO, using the Pin Connector (87408).

The crane is located on the Rear-PTO and uses the new turntable elements (99010, 99009).

 For switching between Front and Rear-PTO a gearbox slides the axles and gears and connect them with the 12T Gear (32270). The axles get connected by pushing them inwards and can easily be disconnected via the crank (33299) on the other side. 

This Mechanism is also shown in the video, also including the other functions in action.
