Hebi Shuangmin JKMD Multi‑Rope Friction Hoist: A Reliable Solution for Large‑Scale Deep‑Mine Hoisting

As mine operations continue to extend deeper and production capacities keep expanding, single-rope winding hoists, constrained by drum rope‑holding capacity and the strength of individual wire ropes, can no longer meet the demands of deep‑shaft, high‑capacity hoisting. Multi‑rope friction hoists, with their unique technical principles and superior performance, are becoming the key equipment for deep‑shaft hoisting in modern large‑scale mines. The JKMD series multi‑rope friction hoists manufactured by Hebi Shuangmin Mining Machinery Co., Ltd. feature a floor‑mounted configuration and are suitable for vertical shaft hoisting in coal, metal, and non‑metallic mines.

Technical Principles and Structural Features

The JKMD series is a floor‑mounted product in the family of dual‑rope, multi‑rope friction hoists. Friction sheave diameters range from 1.6 m to 5.5 m, with all units equipped with four wire ropes and a friction coefficient of 0.25. The complete unit complies with AQ1036‑2007 “Safety Inspection Specification for Multi‑Rope Friction Hoists Used in Coal Mines,” GB/T 10599‑2010 “Multi‑Rope Friction Hoists,” and the company’s internal standard Q/HBSHM006‑2010.

The JKMD series multi‑rope friction hoist employs the flexible‑body friction transmission principle: steel ropes are draped over the friction sheave, and the frictional force between the ropes and the sheave lining drives the hoisting container up and down. Compared with single‑rope winding hoists, multiple steel ropes share the load, allowing for the use of thinner ropes and smaller‑diameter friction sheaves, thereby resulting in a more compact overall unit size.

This product series features a floor‑mounted configuration, with the machine room located directly on the ground, eliminating the need for separate shaft‑tower structures. It is easy to install and maintain, making it well suited for mine renovation and expansion projects. The complete unit comprises key components such as the main shaft assembly, drive system, braking system, head sheave assembly, and electrical control and safety systems. The main shaft assembly serves as the power‑output actuator, handling the hoisting load; the braking system incorporates disc brakes paired with a hydraulic station, providing two‑stage braking capability; and the electrical control system integrates intelligent modules including fully digital speed regulation, PLC control, and online operational condition monitoring.

Core Product Advantages

Highly capable and well-suited for deep wells. The hoisting container and its load are supported by multiple steel wire ropes, resulting in significantly greater lifting capacity and height than single-rope systems. It is suitable for integration with large-scale mines producing up to 4 million tonnes per year.

High safety redundancy. Multiple wire ropes share the load, and in the event of overload, slippage occurs before sudden failure, providing greater safety redundancy. The system is equipped with multiple protective functions, including over‑winding, overspeed, speed‑limiting, brake‑gap monitoring, and rope‑slack detection.

Lower energy consumption and cost-effective operation. The balance‑enhancement system is designed with a smaller drive sheave diameter, resulting in lower system inertia and torque, as well as reduced motor power and energy consumption.

Comprehensive supporting capabilities are in place. Shuangmin manufactures a complete range of mining equipment and components, including head sheaves, cage frames, skip buckets, fall arrestors, tail rope suspension systems, and tension‑automatic balance systems for hoisting ropes, enabling one‑stop, turnkey outfitting of hoisting systems.

Production and Service Assurance

Hebi Shuangmin Mining Machinery Co., Ltd. was established in 2009 and is located in the Shilin Industrial Park of Hebi City, Henan Province. The company is a designated manufacturer of specialized mining equipment and spare parts. It has obtained ISO 9001 certification for its quality management system and certification from the National Coal Safety Center, and is a member of the Coal Safety Association.

The company operates a 25,342-square-meter production base, equipped with 160 sets of manufacturing and processing equipment, and employs over 180 staff members, including 27 specialized technical personnel. It has an annual output capacity of more than 500 hoisting winches of various types. All core components, such as the main shaft assemblies for winches and hoists, are manufactured in-house and undergo final assembly at the company, eliminating reliance on external subcontracting and ensuring quality control from the source.

In terms of product delivery and services, the company offers end-to-end capabilities spanning product design, manufacturing, installation and commissioning, as well as after-sales maintenance. Prior to shipment, all equipment undergoes rigorous inspection and load‑test validation; following delivery, a dedicated technical team provides on-site support for installation and system commissioning, ensuring smooth and reliable startup.

Market Applications

The Shuangmin JKMD series multi-rope friction hoists have been deployed in numerous mining projects across China. In 2026, the company was successfully shortlisted for the tower-type multi-rope friction hoist procurement project of Chifeng Shanjin Hongling Nonferrous Mining Co., Ltd., a subsidiary of Shandong Gold Group, submitting a bid price of RMB 653,880.00, thereby demonstrating the company’s technical expertise and comprehensive manufacturing capabilities in the field of multi-rope friction hoisting equipment.

The company’s products are exported to numerous countries and regions, including Germany, Turkey, Ghana, Tanzania, the Philippines, and North Korea, with its international market presence continuing to expand.
