Double-groove Suspension Head Sheave

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.
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.
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.

Structure Features & Working Principle:
○Sheave Body: Made high-strength alloy steel, either via heavy-duty one-piece forging multi-layer steel plate box welding. The rope groove is precision CNC-machined 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.
○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.

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. 
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.
