What is new in EN 14439 1.3. European Standards: 1.3.5. Improved Safety in Out-of-service Conditions * WIND = Important factor in the stability of the crane * New standards (FEM 1004 1005 and EN 14439) are considering the windload in a more realistic way: realistic way: - Taking in account: 1) cranes height 2) regional wind history This reduces the risk of accident due to out-of-service wind conditons This reduces the risk of accident due to out-of-service wind conditons Slide 25 1. What is new in EN 14439 1.3. European Standards: 1.3.5. Improved Safety in Out-of-service Conditions - Previous standards made no references to different wind areas and used only their national boundaries: wind areas and used only their national boundaries: ex.: cost areas can very different wind conditions ex.: cost areas can very different wind conditions - Reference wind speeds: New standards will be divided according to a wind speed New standards will be divided according to a wind speed level classification (A = lowest ; F = biggest) level classification (A = lowest ; F = biggest) Most of Europe is covered by the C - category Most of Europe is covered by the C - category - Wind Speed Profile: The old standards gave one Wind Speed Profile for cranes The old standards gave one Wind Speed Profile for cranes with heights between 20 m and 100 m: 151 km/h with heights between 20 m and 100 m: 151 km/h The new standard give a more representative wind speed The new standard give a more representative wind speed Profile which is dependent of the height. Profile which is dependent of the height. Slide 26 1. What is new in EN 14439 1.3. European Standards: 1.3.5. 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. 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 reference wind speed followed by a number (10,25,50) for the wind recurrence: the wind recurrence: example: C25 Slide 27 1. What is new in EN 14439 1.3. European Standards: 1.3.5. 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/m FEM 1001: windspeed 151 km/h windpressure: 110 kg/m Example D 50: * tower crane in area D with a 50 year recurrence For a crane at a height of 60 m: For a crane at a height of 60 m: EN 14439: windspeed 193 km/h wind pressure: 180 kg/m FEM 1001: windspeed 151 km/h windpressure: 110 kg/m Slide 28 Support - Loadings Slide 29 Support - Topview crane base Slide 30 Design of the F15 document Slide 31 Slide 32
