The invention provides a steel cord with a construction of n1, n is the number of the steel filaments of the steel cord, the steel cord has an elongation at 2.5N-50N of less than 1.2% and a twist pitch of greater than 16 mm, each of the steel filaments has a form of helical wave with a wave length L expressed in mm and a wave height H expressed in mm when being unravelled from said steel cord, L is greater than 16 mm, each of the steel filaments has a space volume Vs satisfying that, Vs=LH.sup.2/4, and Vs>20 mm.sup.3. The invention steel cord is beneficial for the stress distribution.

A rope system for system level recoil control and method for providing a rope system for system level recoil control are provided. The rope system includes a first rope component and a second component, and the second rope component is connected in series to the first rope component. The first rope component includes a first rope subcomponent and a second rope subcomponent, the first rope subcomponent has predetermined failure strength and is designed and configured to be a controlled failure point for the system, and the second rope subcomponent has a predetermined elongation capability. Upon failure of the first rope subcomponent, the second rope subcomponent is configured to elongate to absorb a predetermined amount of a predetermined operational strain energy of the rope system and to stretch over a predetermined distance and/or predetermined period of time before the second rope subcomponent fails.
