The Return rope (OEM Part No. 3128315026) is a spare part compatible with Simba S7D underground drilling rigs. Manufactured from durable alloy steel, it is categorized as a wear part for the equipment load-bearing support system at the main bracket mount position. This steel wire rope undertakes frequent tension and friction during boom retraction, bearing repeated dynamic loads for resetting telescopic drilling arms. Its high tensile strength alloy steel structure resists abrasion and fatigue, ensuring reliable boom return performance and lowering frequent replacement frequency for mining equipment.
