“This was the first larger model from Lego Technic with the pneumatic function. Unfortunately, it’s noticeable because the pneumatic elements weren’t fully ready yet for series production (e.g. the raising and lowering of the boom only works with the support of rubber rings).... More Otherwise, it’s a very nice model.”

“Set 8851 was released in 1984 as the flagship example of the new pneumatic system. It does not feature any traditional Technic geared systems. Instead, all technical functions are carried out via pneumatic actuators which makes this model less mechanically complex than... More many others of this size. Despite this fact, the model is quite difficult to build. There are many tubes in the chassis which have to be routed just right in order for the whole thing to fit together.”

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.
