Design and Construction Standards
Material Requirements
Below-the-hook lifting devices must be constructed from high-quality materials, such as:
- Alloy steels with high tensile strength
- Corrosion-resistant materials for outdoor or harsh environments
- Materials tested and certified to meet industry standards
Strength and Capacity
Design calculations must ensure the device can safely handle specified loads:
- Design load ratings typically include a safety margin, often 5:1 or higher
- Capacity markings should be clearly visible and durable
Safety Features
Key safety features include:
- Automatic latches to prevent accidental load disconnection
- Load limit indicators or tags
- Fail-safe mechanisms for critical components

Inspection and Maintenance Procedures
Pre-Use Inspection
Operators must perform visual checks before each use:
- Inspect for cracks, deformation, corrosion, or wear
- Verify the integrity of load-limiting devices and safety latches
- Ensure all markings and labels are legible
Periodic Inspection and Testing
Scheduled inspections should be performed by qualified personnel:
- Check for signs of fatigue or material deterioration
- Test load capacity periodically through controlled load tests
- Maintain detailed records of inspections and repairs
Maintenance Practices
Regular maintenance ensures longevity and safety:
- Lubricate moving parts as recommended
- Replace worn or damaged components immediately
- Calibrate load limit indicators periodically

Training and Certification
Operator Training
Proper training is essential for safe operation:
- Understanding device specifications and limitations
- Recognizing signs of wear or damage
- Implementing correct lifting and securing procedures
Certification and Compliance
Personnel involved in the inspection, maintenance, or operation of below-the-hook devices should:
- Obtain appropriate certifications as per OSHA or local regulations
- Stay updated with the latest standards and best practices
- Maintain documentation of training and certifications
