INSTRUCTIONS ON HOW TO CALCULATE THE CRANE'S STAND-
ING STABILITY
* The standing stability should be determined in connection with the commissioning inspection and
made by an authorised installation company or installer.
NOTE! The calculations related to the stability of the vehicle carrying the load crane can be
used only as indicative values. The verification of standing stability should be done experi-
mentally by a test load according to the standard EN 12999.
* The crane is considered to be stable when the sum of overturning moments multiplied by the sta-
bility factor is lower than the sum of moments in which the structure is maintained upright.
* The crane in the most unfavourable position in relation to the overturning edge when under a
static load on a horizontal surface. The vehicle is unladen.
*The stability factor of an installed crane should be approx.
* The factors required for and affecting calculation of standing stability cannot be know in advance,
therefore the standing stability must be determined case by case depending on the truck make,
truck structure, crane's installation location and crane type on the basis of the actual (measured or
calculated) weights and dimensions.
* If, when determining the standing stability, any parameters or questions appear that are not men-
tioned in the truck's maintenance/registration book, please contact the nearest dealer or importer
of the truck make in question. Or Kesla Oyj regarding the crane.
