Sinking head sheaves core load-bearing guiding components vertical shaft excavation, deep well construction, large underground engineering. High-load high-frequency high-reliability vertical hoisting system design. Covers extensive heavy-duty lifting applications.
Shaft sinking phase: Guide ropes kibble sinking buckets, sinking hanging platforms, safety ladders efficiently transport personnel, materials, equipment vertically.
Mine production & roadway extension: Provide stable rope guidance cage hoisting systems, material transfer systems, auxiliary equipment.
Infrastructure projects: Support heavy hoisting vertical transport bridge pile foundation holes, underground diaphragm walls, deep foundation pits.
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: sinking head sheave adopts a modular heavy-duty design, consisting of the following core units
Sheave Body: High-strength alloy steel material, integral heavy forging multi-layer steel plate box welding forming. Superior torsional rigidity fatigue resistance performance. Rope groove precision CNC machining, surface hardening treatment, durable guiding surface.
Bearing System: Fitted large-diameter double-row spherical roller bearings high-strength sliding bearings. Optimized low-speed heavy-load working conditions. Delivers outstanding radial load capacity self-aligning performance.
Support Frame: Heavy-duty steel plate box-welded frame construction, high structural stability. Ground-fixed headframe-mounted installation compatible. Adjustable base plates enable quick on-site setup precision alignment.
Safety Accessories: Anti-rope-jump devices, auto lubrication, vibration monitoring. Enhance safety & maintainability.
Working Principle: head sheave is mounted on the support shaft via a precision bearing system, using rolling friction to ensure smooth rope guidance and power transmission.
Dynamic Load Bearing: Scientifically distributes combined loads from lifting tackle, materials, and rope self-weight, transferring forces efficiently to the support headframe.
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.
