JZ Series Shaft Hoists—The Core Suspension Equipment for Shaft Construction
Release time :
31 Aug,2026
Source:
The JZ series shaft‑drilling winches are specialized suspended equipment for vertical shaft excavation, featuring a static tension of 50–250 kN and a rope capacity of 400–1,300 meters. Manufactured independently by Hebi Shuangmin, they have served numerous mining sites across China and are also exported overseas.
The JZ series shaft sinking winches are specialized equipment used in vertical shaft excavation projects in the mining industry, commonly referred to as “stabilizing winches.” This series of winches is primarily employed during the excavation of vertical shafts in coal mines, metallic mines, and non-metallic mines to suspend and support various tunneling equipment, such as hoisting cages, water pumps, ventilation ducts, and grouting pipes. They also serve to tension and stabilize the hoisting ropes. Additionally, these winches can be used to replace tail ropes connecting the hoisting cage compartments or as surface‑mounted lifting devices.
Structural Features and Operating Principle
The JZ series shaft‑sinking winches are manufactured in strict compliance with standards such as AQ 1031‑2007, “Safety Inspection Specification for Shaft‑Sinking Winches Used in Coal Mines,” and GB/T 15112‑2007, “Shaft‑Sinking Winches.” The products feature a winding‑type design, with key components including the main shaft assembly, reducer, service brake, and safety brake. The main shaft assembly employs a gear‑driven drum to achieve an overhead rope‑out configuration, while the reducer can be either a cylindrical‑gear or planetary‑gear type. The JZ single‑drum shaft‑sinking winch is a single‑drum, winding‑type unit; it is driven by an electric motor through a coupling, reducer, and gear transmission to rotate the drum, offering a compact structure and high transmission efficiency. The double‑drum model utilizes a differential system to synchronize operation, enabling simultaneous dual‑rope suspension and ensuring stable, vibration‑free hoisting of suspended equipment.
Technical Parameters and Product Specifications
This series of winches features Strong lifting capacity, large rope capacity, and smooth operation. Featuring such characteristics, the main models range from JZ‑5/400 to JZ‑25/1300, with maximum static wire rope tension ranging from 50 kN to 250 kN (approximately 5 to 25 tons) and rope capacity from 400 meters to 1,300 meters. Taking the JZ‑25/1300 as an example, it delivers a maximum static tension of 250 kN (about 25 tons) and a rope capacity of 1,300 meters, fully meeting the requirements of shaft sinking operations in kilometer‑deep wells.
The JZP series employs disc brakes and a variable-frequency drive, ensuring smoother and safer operation, enabling stepless speed regulation, and delivering higher control accuracy. The product can be configured with explosion-proof electrical equipment or a variable-frequency drive–based electrical control system to meet customer requirements, making it suitable for underground environments with explosion‑proof standards or specific operating conditions.
Quality Assurance and Service Capabilities
Hebi Shuangmin boasts many years of experience in manufacturing well‑drilling winches. Its core components—such as the spindle assembly, reducer, and drum—are all independently machined, manufactured, and assembled in‑house, eliminating reliance on outsourced processing and ensuring quality control at the source. Prior to shipment, every product undergoes rigorous inspection and comprehensive test‑run verification.
The company offers end-to-end services spanning product design, manufacturing, installation and commissioning, as well as after-sales maintenance. Based on site-specific conditions such as mine depth and suspended load, we provide expert equipment selection and customized engineering solutions to ensure precise alignment between our products and project requirements.
Currently, our products serve numerous mining sites across China, with widespread application in shaft‑driving projects for coal, metallic, and non‑metallic mines, and are exported to multiple countries and regions, including Ghana, Tanzania, Turkey, and the Philippines.
