Sinking head sheaves 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 Single groove models). Rugged, reliable, and adaptableto harsh conditions
Sinking head sheaves are core load bearing and guiding components for vertical shaft excavation, deep well construction, and large scale underground engineering.
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 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.
