LEGO Technic 42242 Mercedes-Benz Unimog U 5023 – Attachment – Rubbish Loader MK2

I have always been a fan of rubbish trucks and rubbish loading equipment. Over the years, I have built several different versions, experimenting with various lifting mechanisms and designs. There is something fascinating about watching a bin being lifted, emptied, and returned to the ground using a clever mechanical system.

After returning my modified LEGO Technic 42242 Mercedes-Benz Unimog U 5023 back to its original tray size, I discovered that my previous rubbish loader attachment was simply too large to fit the revised rear layout. Rather than seeing this as a setback, I took the opportunity to redesign and improve the attachment, resulting in the new Rubbish Loader MK2.

The attachment connects to the rear of the Unimog using my standard rear mounting points, allowing it to be installed and removed quickly. Like the original version, it is powered by the rear PTO output, providing a realistic and functional method of operating the lifting mechanism.

One of the main improvements in the MK2 design is the lifting mechanism itself. The entire system has been strengthened and reinforced, resulting in smoother operation and improved reliability. Despite being more robust, the attachment is also noticeably more compact than the original version.

The reduced size brings another advantage: it uses fewer parts. This leaves more pieces available for designing and building other attachments for the Unimog, something that is becoming increasingly important as the collection of rear-mounted equipment continues to grow.

Using the PTO drive, the Rubbish Loader MK2 is able to lift a rubbish bin, tip it to empty the contents, and then lower it back to the ground. The sequence closely mirrors the operation of real-world bin lifting equipment and provides plenty of satisfying mechanical movement.

I am very pleased with how this updated version turned out. The smaller footprint suits the standard tray configuration much better, while the improved lifting mechanism makes it both stronger and more reliable. It also continues to expand the versatility of the Unimog platform, demonstrating how a single vehicle can be adapted for a wide range of specialised tasks.

The Rubbish Loader MK2 is a great example of how redesigning an existing model can lead to a better result. By making the attachment smaller, stronger, and more efficient, it has become an even more practical addition to my growing collection of Unimog attachments.
