Improved and personalized elements

Few elements have been improved or personalized, in comparison to original Nico71’s version :

  • Additional reinforces for cabin
  • Suspensions fixation on chassis are inclined, to avoid mis-alignment during suspension work
  • Smaller tires (due to lack of larger tires in my Lego Parts inventory)
  • Reinforced steering system, to avoid steering issues
  • Replacement of wheel axles, with 5L with stop axles

The Nico71 version

This truck has been built based on Nico71 Unimog. Nico did a great job and I really enjoyed to replicate his trial truck.
You can click on the image below to see the Unimog by Nico71 on his website, instructions are also available.

Thanks Nico71 for your awesome work!

MOC Dump Truck

This Dump Truck is a personal creation (MOC). This set has no electric motor, and components used are almost studfull. I wanted to build a very realistic vehicle, like old Lego Model Team sets, including few functions with Lego Technic parts.

The Basket Truck has 2 steering wheels. The 4 rear wheels are linked with the small V2 motor. The truck has no hood, so the motor is apparent.

The dump can be moved. It is maintained up or down thanks to a worm. Pneumatic parts or linear actuators should be used for this vehicle, space constraints have prohibited them, particularly because of the 4 rear wheels drive and transmission parts.

The colors were chosen to make the truck realistic. There’s white cab, black is used for the bottom of the cab and the front bumper. Dump is gray, classical. A spare wheel is a present between the chassis and the dump.

Lego Technic 8289 Fire Truck

The Lego Technic Fire Truck #8289 is a nice Fire Truck with nacelle that measures 37 cm length, 14 cm wide and 20 cm high. Sold in 2007, its price was close to 70€, and the set contains 1036 parts. This set has no electric motor, and components used are almost studless. B-Model is an interesting fire 4×4.

This Fire Truck #8289 is quite nice. We can recognize an off-road truck like those who operates in forests. Nevertheless, the front bumper is too high, and the chassis of the truck is very strange in his conception.

On the sides of the truck, 2 stabilizers can touch the ground by turning the 2 gears on the roof. In doing so, the truck is very stabilized and you can easily operate the arm with the nacelle. At the back of the Fire Truck #8289, on the rear bumper, a gear is placed to turn the front wheels. It’s not very nice, but practical and necessary. There is no fake motor.

The arm with the nacelle can be lifted up by a gear on the side of the truck, and turned on 360° by another gear. Movements are good and realistic, it’s a pleasure to play with it.

Lego Technic 8273 Off-Road Truck

The Lego Technic Off-Road Truck #8273 is a very nice Truck that measures 33 cm length, 11 cm wide and 21 cm high. Sold in 2007, its price was close to 60€, and the set contains 805 parts. This set has no electric motor, and components used are almost studless. The B-Model is a 4×4 with 6 wheels, articulated in the center like a Trial Truck.

Lego Technic 8273ˆ Lego Technic 8273ˆ Lego Technic 8273ˆ

The Lego Technic #8273 has numerous functions. There is a direction to the front wheels from the roof rack with, a winch on the front, a crane lifting and rotating rotary, and a tilting dump. Also, the cab tilts like on a real truck, which is very appreciated.
We regret the absence of a motor under the cabin, but the frame of the truck doesn’t allow it.

Lego Technic 8273ˆ Lego Technic 8273ˆ Lego Technic 8273ˆ

Rear wheels are equipped with pendular suspensions, without shock absorbers. Consequently, the truck keeps its wheels on the ground whichever the land on which it operates.
The blue color is good, but I wish only the cab is blue with a black frame to have a more realistic truck.

Lego Technic 8273ˆ Lego Technic 8273ˆ Lego Technic 8273ˆ

The best point of the Lego Technic #8273 is probably his crane arm. The crane arm rotates at 360°, it rises and falls. The crane is designed to pick up pallets on the floor to put them in the dump. Dump can be tilted up with a wheel, but it requires a lot of strength. A linear clutch could solve this problem.

MOC US Truck

This US Truck is a personal creation, built a few years ago. Without an electric motor, components used are almost studfull, with a style like “Model Team” Lego vehicles. The truck measures 28 cm length, 10 cm wide and 15 cm high, it contains few functions: V6 engine, connected to the 8 rear wheels, and front wheels are steered from a little cylinder on the roof of the truck.

Many details are present on the truck. You can see the fuel tanks, the running boards or a complete interior with seat, steering wheel, and dashboard. A canopy roof brings brightness to the living space behind the seats. It includes a bed with a TV.

At the rear of the truck, flexible pipes are ready to be connected to a trailer. Doors can be opened, but the hood is fixed.

Lego Technic 8872 Forklift Transport

The Lego Technic Forklift Transport 8872 is a nice truck designed to carry a yellow forklift. I haven’t build the forklift yet, and we assume that several types of vehicles can be carried on the trailer . The trailer of my model has been extended, and the truck measures now 60 cm length, 9,5 cm wide and 14 cm high. Sold in 1993, the set contains originally 761 parts. This set has no electric motor, and components used are almost studfull.

Front wheels can be directed from the beacon of the truck. The trailer is locked by a mechanical system, and the trailer ramp can be lowered or raised with a small gear on the side.

My modifications on this Lego Technic Forklift Transport 8872 are essentially aesthetic. The tractor of the trailer is now equipped with seats and steering wheel, 2 exhausts are placed at the rear of the cabin, and 2 fuels tanks takes places between the wheels.

The trailer was extended and slightly redesigned to carry numerous cars and trucks of my Lego Technic collection. Also, a winch takes places on the trailer.

The arm is extensible and it can turn 360 degrees. The basket can be raised up, but there are no stabilizers.

All movements are irreversible with the use of worm, except for wheels and directions of course. Also, when I built this truck, I haven’t got pneumatic parts or linear actuators, today we should use those parts for more efficiency and better look.
