The difference between static rope class a and class b

What’s the difference between static ropes A and B? What’s the difference between static ropes A and B? Static ropes are divided into Class A ropes and Class B ropes:

Class A rope: used for hole exploration, rescue and rope passage. Recently, it has been used to connect with other devices and leave or go to another working face in a tense or suspended situation.

Class B rope: used together with Class A rope as auxiliary protection. When using, be sure to keep away from wear, cut and reduce natural wear to reduce the possibility of falling.

The difference between static rope class a and class b

It is forbidden to be used in situations where it is not allowed to be used.

If it is a cave practice, working on a rope, working at high altitude or fixing a rope for rescue and safety, and the user needs to climb freely, the power rope of the symbol and EN892 standard must be used. Ropes with low ductility must never be used when the fall coefficient is greater than 1.

The safety system must ensure that there is a reliable hanging point at the same height or above the user. Relaxation of ropes between users and protection points should be avoided.

Different elements together to form a safety chain (safety belt, connection point, flat belt, hanging point, protection point device, descender) must comply with EN standard and match the rope.

The use of some mechanical devices, such as descending stop devices or other adjustment equipment, should ensure that the rope diameter and other parameters are compatible with it.

It is recommended to use a strong 8-shaped knot when connecting.

Do not use the lock to connect with the user’s safety belt when the user is in danger of falling. The connection point shall be tied at any point of the rope with a figure-of-eight knot. The rope head at the node should extend at least 10cm.
