LEGO Technic 42203 - Attachment - Rubbish Bin Loader MK2

This is an updated version of my rubbish bin loader attachment for the LEGO Technic 42203 Tipping Dump Truck. As part of this build, the original tilt tray has been removed and replaced with a fixed rear tray, creating a more stable and functional platform for future upgrades. The tray sides have also been completely redesigned to better accommodate the rubbish loader mechanism. This new mounting standard will be used across all future attachments for consistency and compatibility.

Key Features:
Bin Loader from LEGO 42167: Adapted from the mechanism in set 42167, the loader has been modified for smoother operation and better integration with the truck chassis.

New PTO Drive System: Control is now mounted at the front of the tray and runs centrally down the body to provide a rear Power Take-Off (PTO). This powers the lifting mechanism for the rubbish bin, which is operated using the black gear at the front of the tray.

Independent Crusher Control: A rear-mounted crusher is integrated into the rubbish bin lifting body and is controlled separately using the black gear located at the top.

Secure Mounting System: The entire attachment slides onto the truck’s chassis and is locked in place at the front with a pair of pins. This ensures stability while still allowing for quick removal and swapping with other attachments.

Next Steps:
This is just the beginning of my modular upgrade path for the 42203 truck. More attachments are in the works to expand its capabilities and transform it into a true multi-role vehicle.
