Western Q-682-Z Series Wire Rope Construction Block - 4 Ton - 3/8 in Wire Rope - 6 in Sheave

Product Description

Product Description: The Western Q-682-Z Series 4 Ton Wire Rope Construction Block is a heavy-duty double-groove rigging block engineered for demanding construction, industrial, and general rigging applications where increased line pull capacity and versatile multi-part reeving configurations are required. Featuring the S-Type New Oval Pattern shell design, this block combines a modern oval profile with robust structural construction suited to a wide range of block and tackle, crane, and rigging systems. This variant accommodates wire rope cable up to 3/8 inch in diameter and is rated to a 4 Ton working load limit, making it well suited to medium to heavy rigging tasks on construction sites, in industrial facilities, and in marine environments where a 3/8 inch rope diameter is preferred or specified.

The two 6 inch sheave grooves allow this block to be used in multi-part line reeving arrangements, enabling greater mechanical advantage and increased effective lifting capacity when configured in a block and tackle system. The 6 inch sheave outside diameter provides a generous rope bend radius relative to the 3/8 inch wire rope, helping to significantly reduce rope fatigue and extend rope service life over repeated heavy-duty lifting cycles. The sheaves run on self-lubricating bronze bushing bearings, 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 deliver consistent performance across a range of operating conditions, resist corrosion, and provide reliable service life in both indoor and outdoor applications without requiring frequent maintenance.

The Q-682-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 double-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 4 Ton or greater, and the block must be inspected before each use in accordance with applicable lifting and rigging safety standards.
