Western Q-681-Z Series Wire Rope Construction Block - 3 Ton - 3/8 in Wire Rope - 6 in Sheave

Description du produit

Product Description: The Western Q-681-Z Series 3 Ton Wire Rope Construction Block is a heavy-duty single-groove rigging block built for demanding construction, industrial, and general rigging applications where reliable performance and durable construction are essential. Featuring the S-Type New Oval Pattern shell design, this block offers a modern oval profile that provides structural strength and a streamlined form suited to a wide range of block and tackle, crane, and rigging configurations. This variant is designed to accommodate wire rope cable up to 3/8 inch in diameter and is rated to a 3 Ton working load limit, making it well suited to medium rigging tasks encountered on construction sites, in industrial facilities, and in marine environments where a smaller rope diameter is preferred or specified.

The single 6 inch sheave provides a generous rope bend radius relative to the 3/8 inch wire rope diameter, helping to significantly reduce rope fatigue and extend rope service life during repeated lifting cycles. The sheave runs on a self-lubricating bronze bushing bearing, a proven and low-maintenance bearing solution well suited to construction and field rigging environments where regular lubrication may not always be practical. Self-lubricating bronze bushings provide consistent performance across a range of operating conditions, resist corrosion, and offer reliable service life in both indoor and outdoor applications without requiring frequent maintenance intervention.

The Q-681-Z Series construction block is designed for integration into block and tackle systems, crane rigging assemblies, and general construction lifting arrangements where a dependable medium-capacity single-groove wire rope block for 3/8 inch rope is required. The S-Type New Oval Pattern shell is compatible with standard rigging hardware including hooks and shackles rated to the appropriate working load limit. All connected rigging components must be rated to 3 Ton or greater, and the block must be inspected before each use in accordance with applicable lifting and rigging safety standards.
