Main Sections and Summaries

1. Anchoring Clamps with Screw Plate (825X Series)

• Codes and working load limits (W.L.L) are provided for single-leg and multi-leg configurations (1 strand, 2 strands, 3/4 strands).
• Load capacities vary by configuration and angle of loading (0°, 90°, 0°-45°, 45°-60°, asymmetric).
• Typical W.L.L ranges from 30 to 100 tons depending on the model and configuration.

2. Weld-On Lashing Rings with Single Base (831X Series)

• Available with or without springs, with detailed dimensional data (A to H in mm) and weights (kg).
• Welding thickness and hardness values (HV + ∆a) are specified for each model.
• Load capacities range from 3,000 to 32,000 daN, suitable for various anchoring needs.

3. Anchoring Brackets with Screw Fixing (835X Series)

• Designed for 3/4 strand configurations with maximum tightening torque values (Nm) specified for each size.
• Thread sizes range from M20 to M48, with corresponding working load limits from 4 to 30 tons.

• Detailed load limits for different strand and leg configurations, including angles of loading.
• Dimensions and weights are provided to assist in selection and installation.

5. Weld-On Lashing Rings with Double Base (821X Series)

• Designed for lifting applications with minimal overall dimensions for anchorage.
• Includes detailed dimensional data, welding thickness, and hardness values.
• Load capacities range from 8,000 to 32,000 daN, with weights from 0.73 to 5.75 kg.

6. Weld-On Lifting Rings with Double Base (820X Series)

• Facilitates easier positioning for lifting and lashing.
• Working load limits range from 4 to 30 tons across various strand and leg configurations.
• Detailed specifications include dimensions, tightening torque, and load limits for different angles.

Critical Information and Best Practices

• Working Load Limits (W.L.L): Each product is rated for specific load capacities depending on the number of legs/strands and the angle of load application. It is critical to select the correct model based on these parameters to ensure safety.
• Installation: Some devices require welding with specified welding thickness and hardness values to guarantee structural integrity. Others are designed for screw fixing, allowing anchorage without welding.
• Load Angles: Load limits vary significantly with the angle of applied force; users must consider the angle to avoid overloading.
• Torque Specifications: For screw-fixed anchoring brackets, maximum tightening torque values are provided to ensure proper installation without damaging components.
• Dimensions and Weight: Detailed dimensional data supports proper integration into structures and helps in planning installation space.

Summary of Tables and Data

• Tables provide codes, load limits, dimensions (A-H), weights, welding thickness, and hardness values for each product type.
• Load capacities are expressed in tons or daN, with configurations for single leg, two legs, and three/four legs.
• Torque values for screw fixings range from 250 Nm to nearly 2000 Nm depending on size.

Conclusion

This document serves as a comprehensive technical reference for selecting and installing anchoring and lifting points. It emphasizes safety through precise load ratings, installation requirements, and product specifications. Users must carefully match product codes and configurations to their application needs, respecting load angles and installation guidelines to ensure reliable anchorage and lifting operations.
