Have you ever wondered what is the logic behind the crane configuration codes used by Liebherr?

How could an unintelligible code such as “SL13DFB” being interpreted?

There is a logic behind the letters used – it has to be found in the German roots of the company.

The letters most frequently used in wind farm construction to define crane configurations are:

SL (“Schwer / Leicht”): This code means that the main boom of the crane is made of two different types of sections, “Heavy” (with a standard area) and “Light” (with a somewhat smaller area, used in the last segment of the boom). Between the “heavy” and the “light” sections s transition element is used

D (“Derrick”): The crane has a secondary boom, called “Derrick”.

F (“Feste Gitterspitze”): The crane use a jib (an auxiliary element assembled on the top of the main boom).

W (“Wippare Gitterspitze”): This is a different type of jib (a luffing fly jib). “WV” is the heavy version.

HS (“Hilfspitze”): This is one more jib configuration specifically designed for wind turbine assembly.

B (“Ballast”): The crane use a suspended counterweights system.
