The Rope tension (OEM Part No. 3128313591) is a spare part compatible with Simba S7D underground drilling rigs. Manufactured from durable alloy steel, it acts as a mechanical component for the cable tension adjustment system at the rope tensioning assembly position. It precisely controls wire rope tightness to stabilize telescopic boom movements, offset tension loss during repeated operation, and reduce rope abrasion underground. With high structural toughness and accurate dimensional tolerance, it ensures smooth traction performance and extends the service cycle of rig cable systems.
