Guideline for new crane standards
FEM Wind zone classification
EN / EN 14439

24. 1. What is new in EN 14439
1.3. European Standards:
Improved Safety in Out-of-service Conditions
* WIND = Important factor in the stability of the crane
* New standards (FEM 1004 – and EN 14439) are considering the windload in a more
realistic way:
- Taking in account:
1) crane’s height
2) regional wind history
 This reduces the risk of accident due to “out-of-service” wind conditons

25. 1. What is new in EN 14439 1.3. European Standards:
Improved Safety in Out-of-service Conditions
- Previous standards made no references to different
wind areas and used only their national boundaries:
ex.: cost area’s can very different wind conditions
- Reference wind speeds:
New standards will be divided according to a wind speed
level classification (A = lowest ; F = biggest)
Most of Europe is covered by the C - category
- Wind Speed Profile:
The old standards gave one Wind Speed Profile for cranes
with heights between 20 m and 100 m: 151 km/h
The new standard give a more representative wind speed
Profile which is dependent of the height.

26. 1. What is new in EN 14439 1.3. European Standards:
Improved Safety in Out-of-service Conditions
- Wind Recurrence :
Wind speed profiles can be set according to various levels,
based on the time period considered for identifying the highest
probable windspeed. “ The longer the time period, the more
probable it is to find bigger storms”
Typical wind speed profiles are defined for:
* 10, 25 or 50 years
* 25 is recommended for tower crane
- C category is the minimum required reference wind speed
so even A en B are C.
- In commercial and technical documents a letter (C,D,E, F) for
the reference wind speed followed by a number (10,25,50) for
the wind recurrence:
example: C25

27. 1. What is new in EN 14439 1.3. European Standards:
Improved Safety in Out-of-service Conditions
Example C25:
* tower crane in area C with a 25 year recurrence
* For a crane at a height of 60 m:
EN 14439: windspeed 161 km/h
wind pressure: 120 kg/m²
FEM 1001: windspeed 151 km/h
windpressure: 110 kg/m²
Example D 50:
* tower crane in area D with a 50 year recurrence
For a crane at a height of 60 m:
EN 14439: windspeed 193 km/h
wind pressure: 180 kg/m²
