Cement Mixer

42112-1 Technic 2020 1161 parts 3.1% repair risk Intermediate

The LEGO Technic Cement Mixer (42112-1), with its 1161 pieces, meticulously recreates a vital construction vehicle. This detailed model features 8 robust wheels and an opening driver’s cab, providing access to the internal mechanisms. A prominent large mixing drum simulates real-world operation; it rotates automatically as the truck is pushed or can be turned manually via a separate gear. For unloading, turning the drum counterclockwise dispenses the 'concrete' — represented by 100 1x1 LEGO bricks. An articulated funnel system, controlled by a dedicated handle, guides the 'concrete' into position, while a moving motor detail adds to the model's authentic feel and complex Technic functionality. This replica stands as a functional display piece showcasing engineering principles.
