Product IntroductionThe multi-rope friction hoist head sheave is the core guiding device for floor-type multi-rope hoisting systems, typically installed at the top of the headframe. Its main function is to precisely change the running direction of the steel wire ropes and maintain the synchronization of multiple ropes.
Application Scope:
Main and auxiliary shaft hoisting in deep coal mines:
Used for hoisting coal and gangue, as well as transporting personnel, equipment, and materials. Meets the comprehensive demands of high production capacity and deep mining depths.
Main shaft hoisting in large metal mines:
Used for high-load, high-efficiency centralized hoisting of metal ores such as copper, iron, and gold.
Other deep vertical shaft projects:
A key equipment suitable for applications requiring large hoisting capacity, serving high-yield, deep well mining operations. Compared with traditional single-rope drum winders, the sheave for multi-rope friction hoists offers significant advantages in terms of hoisting capacity, hoisting height, equipment compactness, and operational safety.
| Structural Features and Working Principle |
The core structural design of the multi-rope friction hoist head sheave lies in its unique combined mechanism of fixed sheave and floating sheave.The fixed sheave acts as the static support foundation of the system, undertaking main load bearing and basic guiding functions, and providing a stable structural fulcrum for overall operation.The floating sheave adopts an axial micro-floating design, which can perform real-time and accurate compensation for the dynamic displacement of steel wire ropes during operation. |
| Core Advantages & Value Safety: "Fixed-floating" mechanism + auto tension balancing prevents single-rope overload. Boosts system safety redundancy. Efficiency: Uniform multi-rope force. Smooth operation. Less vibration/shock. Supports high-output, large-tonnage hoisting. Low Maintenance: Reduces uneven rope wear. Extends service life. Cuts downtime for rope adjustment. Lowers operating costs. Reliability: Critical tech for safe, continuous deep mine operation. Ensures stable core hoisting performance. |
