The tightening torques given apply to the threads and bearing surfaces of the nuts greased. During assembly and before the rope is taken into service, the collar nuts must be tightened to the prescribed torque. After the load is applied for the first time, the tightening torque must be checked again and, if necessary, corrected. (Extracted from DIN 1142)
