Milan Reindl, the AFOL made LEGO Technic Designer, initiated a 3 part article dedicated to The History of Technic, at LEGO Technic blog - The official one!
This first part of the series is devoted to the Cranes produced by LEGO in more than 35 years of LEGO Technic history.
More precisely it all started with the Expert Builder sets, before anyone ever eared about Technic. Or if we want to go back long enough, than maybe it all started with some pré-Technic sets under the Gears "theme". But these are too much details for the audience of the blog, hence not mentioned in this version of the history.
It is however a good reading for you to have a flashback on how LEGO Technic cranes have evolved along the time.
Don't loose the next part, which will cover the evolution of LEGO Technic helicopters and planes.
Enjoy your memories!
