Hebi Shuangmin Tianlun Products: Key Guiding Components for Mine Hoisting Systems

The head sheave is a critical component of the mine hoisting system, responsible for changing the direction of the wire rope, providing support, and transmitting power. It is mounted at the top of the headframe or in the shaft tower. As the hoist drum rotates to wind or unwind the wire rope, the rope first contacts and engages with the sheave’s groove; friction between the rope and the sheave’s rim drives the sheave to rotate, converting the rope’s linear motion into rotational motion. After being redirected, the wire rope descends to suspend and raise various containers within the shaft. Hebi Shuangmin Mining Machinery Co., Ltd. manufactures a full range of mining‑grade head sheaves, enabling complete integration with hoist mainframes, headframes, cage systems, skip buckets, and other equipment to form a comprehensive hoisting system.

Product Classification and Structural Features

According to the coal industry standard MT/T 327-2011, head sheaves are classified into three types—shaft head sheaves, shaft sinking head sheaves, and traveling head sheaves—based on their hoisting method and application. Shuangmin’s range of head sheave products covers the primary application scenarios in mine hoisting.

Fixed Crown Sheave With a simple structure, high strength, and easy maintenance, it is particularly well suited for applications where wire ropes are wound onto drums without significant angular deviation or where precise alignment is required, such as in single‑rope winding hoists. The sheave body rotates only, offering excellent fatigue resistance and deformation resistance, making it ideal for long‑term heavy‑load operations under high‑frequency use. Sheaves are available in three configurations: monolithic cast steel, welded construction, and molded steel‑plate rim; all utilize rolling bearings.

Well drilling and overhead pulley suspension The equipment is designed to match the maximum static tension of wire ropes used in JZ‑series shaft‑sinking winches, covering a range of specifications from 5 t (50 kN) to 40 t (400 kN). It is suitable for operating conditions during the shaft‑driving phase, supporting hoisting platforms, pipe‑stabilizing devices, and rope‑guiding systems. The double‑sheave shaft‑sinking suspension head sheaves are available in single‑groove and double‑groove configurations; the double‑groove version features an adjustable design that allows the sheave and bearing housing to be fine‑tuned, enabling selection and customized assembly based on specific application requirements.

Multi-rope friction sheave It is an essential component of a floor‑mounted multi‑rope friction hoist, and the ratio of the head sheave diameter to the diameter of the hoisting wire rope must comply with the relevant provisions of the applicable codes.

Market Applications and Export Performance

Shuangmin’s hoisting sheaves have been deployed at numerous domestic mining sites and overseas projects. In 2020, a German customer made a special visit to the Hebi Shuangmin factory for an on-site inspection and subsequently placed an order for multi‑rope friction sheaves, underscoring the international competitiveness of the company’s sheave products.

In its market‑expansion efforts in 2026, the company successfully secured a place on the shortlist for the first batch of pulley‑wheel procurement projects of China National Coal Group Xinji Energy Co., Ltd., submitting a bid of RMB 2.386 million. The project stipulates delivery within nine months of the contract’s effective date. According to available performance records, Shuangmin has previously supplied JKMD‑series hoists and pulley‑wheel assemblies to numerous mining enterprises, including Qian’an Haode Mining Co., Ltd., Kazuo County Xinyou Mining Co., Ltd., Panshi Guangfeng Mining Co., Ltd., Chifeng Tianma Mining Co., Ltd., and Baotou Weiyе Economic and Trade Co., Ltd. Consistent inclusion in the tender lists of major mining groups underscores the company’s comprehensive manufacturing capabilities in pulley‑wheel and related auxiliary equipment.

Production Assurance and Service Capabilities

Hebi Shuangmin Mining Machinery Co., Ltd. was established in 2009 and is located in the Shilin Industrial Park of Hebi City. 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 major manufacturing and processing equipment, and employs over 180 staff members, including 27 specialized technical personnel. In addition to head sheaves, the company offers a comprehensive range of mining equipment and components, such as derricks, single- or multi-rope cage systems, skip buckets, fall‑arrest devices, wedge‑type rope loops, tail‑rope suspension systems, and automatic tension‑balancing hoisting‑rope suspension units, thereby meeting customers’ one‑stop procurement needs. As a guiding component at the top of the derrick, the head sheave is precisely matched to the hoisting drive unit, with exact installation dimensions, and has been exported—alongside the host equipment—to numerous countries and regions, including Germany, Turkey, Ghana, Tanzania, the Philippines, and North Korea.
