MOD / MOC - 42151 C Model American Truck - Attachments

[Paul B Technic]

Recently I have built and reviewed the American Truck C model of set 42151, which was designed by "ConstructionsByDonat". While I found this to be a well designed and built C model, I felt with some changes it could be a good base for expanding it. I spent sometime working on some changes, these include: - Redesigning the cabin roof and supports, to better lock this in position and give it a more polished and finished look.

- Reducing the height of the exhaust pipe.

- Change to dual rear axels.

- Swapping the rear wheels to offroad type tread.

- Extending the rear body, this it is allow various attachments to be connected.

 

After doing all of the above, I decided it would be fairly easy to modify my cherry picker attachment from my UORT and mount this on to the rear. This lead to me pulling my UORT and most of it's attachments apart, and using these parts to improve this truck and also modify my cherry picker attachment. This now has a solid mounting system and can easily be removed from the truck with only one axle being removed from the rear, but it is still solid enough to not allow the cherry picker attachment to come off. My plan is to now build some different attachments for this.

MOC - 42151 C Model American Truck - Tow Arm

 

 I would like to present my latest MOC attachment for my modified LEGO Technic 42151 C Model American Truck, this is a tow arm.

It features a tow line, which is controlled by the yellow gear on the side of the body. It also has a locking stem, to keep the tow line in place.

 

This attaches using the same mounting points and system as my previous attachment and this is the standard mounting system I will use with this truck for attachments in the future.

Thanks for the reply. I am planning on finishing a couple more attachments, then will go back and improve some of these.

MOC - 42151 C Model American Truck - Recovery Tow Attachment Mk2

 

As a passionate LEGO Technic builder, I'm thrilled to share my latest creation: the Recovery Tow Attachment Mk2 for the LEGO Technic 42151 C Model American Truck. This custom design transforms the standard American truck into a powerful recovery vehicle, ready to tackle any heavy-duty towing job. Below, I'll take you through the inspiration, design process, and features of this unique MOC (My Own Creation).

The inspiration for the Recovery Tow Attachment Mk2 came from my fascination with real-life tow trucks and their complex machinery. I wanted to create a realistic and functional attachment that could seamlessly integrate with the LEGO Technic 42151 C Model American Truck. My goal was to design an attachment that not only looked authentic but also provided a challenging and rewarding building experience. This attaches using the same mounting points and system as my previous attachment and this is the standard mounting system I will use with this truck for attachments in the future.

I started by studying various types of recovery tow trucks and their mechanisms. Using my existing collection of LEGO Technic pieces, I built several prototypes to test different mechanisms and configurations.

Each prototype helped me refine the design, ensuring that the attachment was both functional and aesthetically pleasing.
After multiple iterations, I finalized the design and created a detailed parts list.

The final build involved careful assembly, ensuring that all moving parts operated smoothly and the attachment securely connected to the truck.

The Recovery Tow Attachment Mk2 has two features:
- Tow Arm with Tow Line: This is controlled by the front set of black gears and has a lever to automatically lock this line in place as it is reeled in.
- Recovery Lifter: This is controlled by the rear set of black gears and is used to lift the wheels of the towed vehicle to allow his to be safely towed.

Overall, this is the attachment I have spent the most time and effort on designing and building, I am very happy with how it has turned out.

My final mods for this MOC. I have now removed the second set of rear wheels which I had added and have removed the mounts for my attachments, I am now using these on my other truck.

Below is a video of my changes, to make this in to a race truck.
