For mining industry, certain rope properties such as improved resistance to shock loading and higher bending fatigue life were becoming of critical importance. To meet these requirements, in the year 2005, after installation of our Plastication Line, Usha Martin manufactured Powerform Valley Filled & Cushion Core Ropes.
These Ropes have locked lubrication, to provide clean working environment, and plastic impregnation, to keep out external particle, dirt, and dust. In addition, these ropes were designed with smooth contact over drum and sheave in order to reduce abrasion wear. The quality testing results of the rope showed that the ropes exhibited higher bending fatigue life and higher resistance to shock loading.
