Pulleys, drums, chains or ropes. Pulleys, drums and wheels must have a diameter commensurate with the size of rope or chains with which they can be fitted. Drums and wheels must be so designed, constructed and installed that the ropes or chains with which they are equipped can wind round without falling off. 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.
Lifting chains have a working coefficient chosen so as to guarantee an adequate level of safety; as a general rule, this coefficient is equal to four.
