Technic Concrete Mixer Truck 42112

This Technic Concrete Mixer Truck, set number 42112, was released in 2020 as part of the popular Technic theme.

BuyMyBricks now supplies sealed original examples sourced from verified suppliers.
In depth

The full description

The LEGO Technic Concrete Mixer Truck 42112 is a retired set that showcases the engineering excellence LEGO Technic is renowned for. This factory-sealed release represents a genuine piece of LEGO history, offering the complete building experience exactly as it left the factory. Whether you’re a dedicated Technic builder or expanding your collection, this is an opportunity to own a set that’s no longer in production.

What You Get

  • Complete, factory-sealed LEGO Technic Concrete Mixer Truck 42112
  • All original pieces, instructions, and packaging intact
  • Authentic LEGO construction with motorised mixing drum functionality
  • Detailed working mechanisms characteristic of the Technic range
  • Collectible retired set in pristine condition

Why This Set

Technic sets are built for builders who appreciate mechanical depth. The Concrete Mixer Truck 42112 delivers exactly that, a satisfying construction experience with functional, motorised elements that reward your time spent building. The mixing drum rotates realistically, and the truck’s chassis is engineered with the precision you’d expect from the Technic range. Once built, it becomes a striking display piece that captures the engineering ingenuity behind everyday vehicles. This set engages you during the build and impresses afterwards, making it ideal for both serious builders and those seeking a model with genuine mechanical character.

Condition Guarantee

This set arrives factory-sealed in its original packaging. We’ve verified its authenticity and condition before listing, so you can build with complete confidence. Every piece is guaranteed to be present and correct, as it has never been removed from the factory seal. You’re receiving the set exactly as LEGO produced it, no surprises, no missing elements. Your building experience will be exactly what the designers intended.

Shipping & Returns: Free tracked UK delivery on orders over £85. If you’re not entirely satisfied, we offer a 30-day returns policy. No questions asked.

Common questions

The things people ask

Is it genuine and factory sealed, and what if it is not?
Every set is checked before it is listed: the factory seals and tape first, then the corners and edges, and anything worth knowing about the box goes on the listing. If a set from us is not genuine and factory sealed, tell me and I refund in full and pay the return postage. We sell sealed retired sets and nothing else, so there is no opened or used stock for yours to get mixed up with. Returns for any other reason are within 30 days, sealed, as the returns policy says.
When will it arrive?
Order before 3pm on a working day and it goes out the same day, tracked and insured. UK orders arrive within 1 to 3 working days, and you get the tracking number by email as soon as it is on its way. Tracked UK delivery is free over £85.
How is it packed, and what if the box arrives damaged?
The set box travels inside a second carton with fill, so the courier handles the outer box and not the one you are keeping, and every parcel is insured to its full value. If it still turns up damaged, photograph the outer packaging and the set box before you unpack any further, then email support@buymybricks.com with the photos and your order number the same day. We reply the same working day with a replacement if we have one or a full refund, and we deal with the courier claim ourselves so you do not have to.
Do you ship outside the UK?
Yes to the United States and Canada, with tracked and insured delivery costed at checkout before you pay. We do not ship to the EU at the moment. Everywhere in the UK is covered by the standard tracked service.
Can I return it?
Yes, within 30 days of delivery. If it arrived damaged or not as described, tell us and we pay the return postage and refund in full or replace it. If you have simply changed your mind, the set needs to come back sealed and as it arrived, and the return postage is yours. The refund goes back to the card you paid with within 3 working days of the set landing back with us. Use a tracked service so there is proof of delivery.
Is there a discount code?
Yes. Join the email list on any page and your first-order code comes through in the first email, along with what has just landed. We do not print the code on the site, so the list is the way to get it.
Can I pay in instalments?
Yes. Klarna Pay in 3 is at checkout: three equal payments, no interest and nothing extra to pay. Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay and Shop Pay are all there too. Payment is handled by Shopify Payments and we never see your card details.
Is it going to be a gift?
Tell us in the order notes at checkout and no prices or invoice go in the parcel. Sending it straight to them is fine: put their address as the delivery address and keep yours as the billing address.
Can I have a VAT invoice?
Yes. We are VAT registered and every price on the site already includes VAT. Reply to your order confirmation asking for one and it comes back the same working day. For a business or bulk order, email support@buymybricks.com before you buy and we will sort an itemised invoice.
Not the set you want?
Tell us the set number and we will look for a sealed one through the trade. If we find one at a sensible price you get an email with the link before it goes on the site. Ask us to find it.

Not answered here? Email support@buymybricks.com or ring 01904 900212. A person reads it, usually the same day.
