The 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, highreliability 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.
