The GBC Balls are patiently waiting in line, ready for their next adventure.
But there’s one question:
How do you think they’re going to get to the top?
We’ve been putting the legendary LEGO Technic 8258 Crane Truck to work in a completely different way, transforming it into our newest Great Ball Contraption:
GBC 62 Lifting Factory
Can you guess the lifting mechanism before we reveal it? Drop your theories in the comments!
The folks at Brickworld Chicago 2026 did it again!
Their latest Great Ball Contraption layout is putting the spotlight on our incredible GBC Glow Balls! As the balls travel through a mesmerizing network of lifts, ramps, and moving mechanisms, they create a stunning glowing effect that takes the Great Ball Contraption experience to a whole new level.
From smooth ball flow to eye-catching illumination, this layout is a perfect showcase of how our GBC Glow Balls can transform any GBC into a captivating display. Whether you’re a LEGO Technic enthusiast, a GBC builder, or simply love kinetic creations, this is one you don’t want to miss! Great Ball Contraptions are designed to move balls continuously through interconnected modules, creating fascinating mechanical displays.
Imagine your own GBC glowing at events, exhibitions, or in your LEGO room!
Last week we asked you to guess which LEGO Technic set was getting the GBC treatment…
And some of you got it right!
(Enjoy those well-earned bragging rights 😄)
And the answer is… the LEGO Technic 8258 Crane Truck set.
Originally released in 2009, the LEGO Technic 8258 Crane Truck was one of the standout Technic sets of its era. With 1,877 pieces, Power Functions, a motorized crane, extendable outriggers, steering, and a detailed V8 engine, it was packed with impressive mechanical features.
More than 15 years later, this classic Technic icon gets a completely new life as a Great Ball Contraption module!

A huge thank you to Paul Beugelsdijk for building our GBC 61 – RAAF module and for sharing his experience with us.
“What a fun build! Attention to detail of the build will result in a very satisfying and reliable GBC.”
Paul even took it a step further by designing and adding his own return ramp, creating an even smoother ball return and adding more action to the module. We love seeing builders put their own creative spin on our designs!
Paul also shared a wonderful story about how his passion for building started. After his family emigrated from the Netherlands to the USA in 1956, one of his favorite Christmas memories was receiving a Tinker Toy set—a building toy that sparked a lifelong love for creating, eventually leading him to LEGO® Technic and GBC.
Watch Paul’s GBC 61 in action here and if you’d like to build your own GBC 61 – RAAF, you can find the instructions here.
Thank you again, Paul, not only for sharing your build and story, but also for leaving us a wonderful review. Happy building!
