Construction Block With Shackle 2 Sheaves

Outlines the 2-sheave CB series, supporting loads from 30 up to 140 UStons. The document provides exhaustive technical dimensions and weights, focusing on high-durability performance for mobile and land-based crane operations.

High-Capacity Lifting Utility: Construction Block with Shackle (2 Sheaves)

The Construction Block with Shackle (2 Sheaves) is a heavy-duty rigging component designed for versatile lifting and construction applications requiring multi-line reeving. These blocks feature a dual-sheave configuration to increase mechanical advantage and are supplied with a high-strength shackle attachment as standard. Each unit is manufactured for high-durability performance and is standard-fitted with bronze bearings to ensure smooth operational rotation.

Safety-First Engineering and Performance
  • Structural Integrity: Engineered with a Minimum Ultimate Strength equal to four times the Working Load Limit (4 X WLL) to provide maximum structural safety during operations.
  • Extended Capacity Range: Standard 2-sheave models support Working Load Limits (WLL) from 30 UStons up to 140 UStons.
  • Quality Assurance: While standard models are provided, Ropeblock offers custom versions tailored to specific project requirements.
  • Document-Led Manufacturing: Technical drawings are submitted for approval prior to production, serving as the definitive document for final dimensions.
Flexible Attachment and Design Integration
  • Attachment Versatility: Beyond the standard shackle, optional configurations are available, including units with a hanger, pin, swivel eye, or swivel jaw.
  • Broad Rope Compatibility: Precision-engineered to accommodate wire rope diameters ranging from 1/2″ up to 1-1/2″.
  • Optimized Service Life: To maximize rope and sheave longevity, users should adhere to wire rope manufacturers’ D/d ratio guidelines.
