“This model is one of the best Lego Technic models. Firstly, it has many functions. Secondly, it greatly resembles the original. The model makes enormous fun, which begins with assembling. Even though there’s no alternative model, the superstructure can be replaced by a... More cherry picker. I highly recommend this model and so it gets the highest rating.”

BrickEconomy Member Review
“I spent hours building this model and found the telescoping crane arm particularly intriguing, adding unique functionality. The large number of pieces makes it a valuable parts pack. Overall, it's a substantial and enjoyable set, despite some minor issues with the string and clutch gears.”
 

About Technic

TECHNIC is one of The LEGO Company's main lines based on creating detailed model machines and mechanical toys with specialized beams, axles, gears and connectors and primarily designed for older children and adults. The theme was first introduced as the Expert Builder series in 1977, but was officially renamed as TECHNIC in 1984. TECHNIC is still an active theme, and is one of the longest running themes in LEGO history. While most TECHNIC sets are vehicles that use pieces to mimic real vehicles, such as engine pieces, suspension, pneumatic, and transmission pieces, the TECHNIC parts have been used by various other System themes as well as LEGO Mindstorms.
