6.8 Outdoor use
When the lifting system is used outdoors, you must take account of the maximum
permissible wind speeds. Maximum permissible wind speeds for various types of
vehicles are given in the next table.
 The values in the table are averages and may only be used as a guideline.
The maximum permissible wind speed depends on both the type of vehicle and its
weight. When hoisting large vehicles with high sides, the values for lighter vehicles
should be observed.
