the arithmetic ratio between the load guaranteed by the manufacturer up to which a piece of equipment, an accessory or machinery is able to hold it and the maximum working load marked on the equipment, accessory or machinery respectively
Kinnitusotsikutega varustatud trosside koormusvaruteguri väärtus ei tohi olla väiksem kui 5. Tõstekettide koormusvaruteguri väärtus ei tohi olla väiksem kui 4. Selleks, et kontrollida varutegurit, peab kraana tootja läbi viima lasti tõstmiseks ettenähtud trossi- või ketitüübi ja nende kinnitusotsikute koormuskatsetused.
Ropes used directly for lifting or supporting the load must not include any splicing other than at their ends (splicings are tolerated in installations which are intended from their design to be modified regularly according to needs of use). Complete ropes and their endings have a working coefficient chosen so as to guarantee an adequate level of safety; as a general rule, this coefficient is equal to five.
