Product IntroductionThe sinking head sheaves are purpose-built to guide and support steel wire ropes during vertical shaft construction. Available in single-groove and double-groove designs, they feature durable alloy copper bushings, integrated lubrication oil cups, and adjustable spacing (for double-groove models). Rugged, reliable, and adaptable to harsh conditions, they are a critical upgrade for your deep well and underground projects, ensuring safer, more efficient operations.
Application Scope:
Sinking head sheaves are core load-bearing and guiding components for vertical shaft excavation, deep well construction, and large-scale underground engineering. Designed for high-load, high-frequency, high-reliability vertical hoisting systems, they serve a wide range of heavy-duty lifting applications:
Shaft sinking phase: Guide ropes for kibble sinking buckets, sinking hanging platforms, and safety ladders to efficiently transport personnel, materials, and equipment vertically.
Mine production & roadway extension: Provide stable rope guidance for cage hoisting systems, material transfer systems, and auxiliary equipment.
Infrastructure projects: Support heavy hoisting and vertical transport for bridge pile foundation holes, underground diaphragm walls, deep foundation pits, and other large construction projects.
Emergency & maintenance tasks: Handle temporary, high-load lifting operations such as underground equipment repairs and emergency rescue hoisting.
Single-groove sheaves are primarily used to suspend hanging platforms, formwork, and stabilizing ropes, while double-groove models are ideal for hanging ventilation ducts and pipelines during construction.
| Structure Features & Working Principle: |
Structure Features: The sinking head sheave adopts a modular heavy-duty design, consisting of the following core units ○Sheave Body: Made of high-strength alloy steel, either via heavy-duty one-piece forging or multi-layer steel plate box welding. It delivers excellent torsional rigidity and fatigue resistance. The rope groove is precision CNC-machined and surface-hardened for a durable guiding surface. ○Bearing System: Equipped with large-diameter double-row spherical roller bearings or high-strength sliding bearings, optimized for low-speed, heavy-load conditions, offering superior radial load capacity and self-aligning performance. ○Support Frame: Built with heavy-duty steel plate box-welded frames for high stability. It supports ground-fixed or headframe-mounted installation, with adjustable base plates for easy on-site setup and precision alignment. ○Safety Accessories: Integrated with anti-rope-jump devices, centralized automatic lubrication systems, and vibration monitoring interfaces to enhance operational safety and maintainability. |
| Working Principle: The head sheave is mounted on the support shaft via a precision bearing system, using rolling friction to ensure smooth rope guidance and power transmission. During hoisting system operation Dynamic Load Bearing: Scientifically distributes combined loads from lifting tackle, materials, and rope self-weight, transferring forces efficiently to the support headframe for stable operation. Adaptive Guidance: Optimized groove curve design adapts to changes in the rope’s running path, significantly reducing uneven wear and extending rope service life. Shock Absorption & Buffering: High-rigidity structure and precision bearing clearance control absorb impact vibrations from start-up, braking, and sudden load changes, protecting the entire hoisting system. |
