Product Description

Product Description

Key Technical Specifications:

• Material Composition: Forged from 34CrNiMo6 alloy steel with trace element optimization for enhanced fatigue resistance.

• Surface Treatment: Electro-galvanized (HDG) coating with 85μm minimum thickness, compliant with ISO 1461 for 3,000+ hour salt spray resistance.

• Dimensional Precision: CNC-machined throat opening maintains ±0.25mm tolerance to prevent accidental disengagement.

• Certifications: DNV-GL, ASME B30.10, and EN 1677-1 compliant with full traceability documentation.

 

Intelligent Safety Features:

1. Auto-Locking Latch Mechanism: Spring-loaded safety latch with dual-stage engagement prevents accidental release, even under vibration or shock loads up to 2g.

2. Load Direction Indicators: Laser-etched arrows specify permissible loading angles (0°-120°) to prevent side-loading failures.

3. Non-Marring Jaw Design: Precision-ground contact surfaces with hardened inserts (HRC 50-55) prevent wire rope abrasion during grab operations.
