the arithmetic ratio between the load used to carry out the static or dynamic tests on a piece of equipment, an accessory or machinery and the maximum working load marked on the piece of equipment, accessory or machinery
Kraana tuleb projekteerida vastupidavana staatilisele ja dünaamilisele koormuskatsele. Üldjuhul viiakse katsetused läbi katsetuse teguri kordsel nimikoormusel. Arvutustes peab staatilise katsetuse teguri valima sellise, mis tagab piisava ohutuse. Käsiajamiga kraanadel on staatilise katsetuse tegur 1,5 ja masinajamiga kraanadel 1,25.
The machinery and the lifting accessories must be designed and constructed to withstand the overload in the static tests without permanent deformation or patent defect. The calculation must take account of the values of the static test coefficient chosen to guarantee an adequate level of safety: that coefficient has, as a general rule, the following values:
(a) manually-operated machinery and lifting accessories: 1,5;
(b) other machinery: 1,25.
