Precautions for the use of 7*7-3.6mm wire rope:
1. Do not use the new 7*7-3.6mm wire rope directly under high speed and heavy load immediately, but work under low speed and medium load for a period of time. After the new rope gets used to the operating conditions, gradually increase the working speed of the wire rope and increase the lifting load.
2. The 7*7-3.6mm wire rope should not be strongly squeezed during use, so as to avoid deformation of the steel wire rope, resulting in structural damage and early broken wires, broken strands or even broken ropes, which will significantly reduce the service life of the steel wire rope and endanger the safety of work.
3. When the 7*7-3.6mm wire rope is working at high speed, it should prevent it from rubbing against other objects outside the non-matching wheel groove. Due to the instantaneous frictional heat generated when the 7*7-3.6mm wire rope and these objects work with each other at high speed, the surface layer of the steel wire can show a martensite structure, and although this change in structure cannot be discerned by the naked eye, it is It is the main cause of the early fracture of the steel wire.
4. When the 7*7-3.6mm wire rope is wound on the drum, it should be arranged as neatly as possible. If it is loosely wound, the structure of the steel wire rope will be damaged due to the mutual extrusion of the steel wire rope during operation, and early broken wires will directly affect the service life of the steel wire rope.
