Rope Testers
The LMA Signal measures loss of metallic cross-sectional area (LMA) caused by corrosion, abrasion, etc. The LMA Signal is quantitative and can be calibrated. (Typically, a rope must be retired when the LMA exceeds 10%).The WRR Signal measures wire rope roughness (WRR). WRR is defined as the aggregate surface roughness of all wires in a rope. WRR is typically caused by and indicates internal and external corrosion pitting, broken wires and clusters of broken wires. The WRR signal is quantitative, and it is calibrated together with the LMA Signal.The LF Signal can indicate localized flaws (LF), for example, broken wires, corrosion pitting, etc. Because it is only qualitative - and cannot be calibrated - it is of limited value for assessing rope deterioration and for making rope retirement decisions.
