National Project Demonstration Engineering—Shandong Gold Group Xincheng Gold Mine JKM-5.5×6 (III) Tower-Type Multi-Rope Friction Hoist

　　In 2021, Shandong Gold Group’s Xincheng Gold Mining Co., Ltd. developed and manufactured the main‑shaft hoisting equipment—the JKM‑5.5×6 (III) type multi‑rope friction hoist—featuring a novel external wedge‑type support friction sheave design and a high‑torque composite coupling technology. The new main shaft has a depth of 1,527 m, adopts a tower‑type layout, and employs a double‑bucket hoisting system with a bucket capacity of 18 m³. The hoist is driven by a 5,800 kW motor and is tasked with conveying 6,000 t/d of ore and 1,200 t/d of waste rock from underground.

　　The main unit of the JKM-5.5×6 (III) multi-rope friction hoist was shipped to the site on October 12, 2023. At present, the guide sheave assembly has been fully installed, and the spindle assembly and motor are essentially in place; installation of the remaining components will proceed sequentially.
