“I am glad I bought this. Its real strength lies in its… strength, and it's clearly been engineered to be useful and playable, and not just decorative; its compromises are all made in the direction of playability and robustness and for that I applaud it. LEGO's best crane,... More bar none.”

Brickipedia
“It features the second largest piece count ever (the first is 42055 Bucket Wheel Excavator, at 3,929 pieces) for a Technic set at 2606 pieces, and includes a power functions large motor and a power functions battery box. The set has a 4-mode gearbox on the crane's... More superstructure that controls the outriggers, hook, extend boom and raise/lower boom.”

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.
