A lifting hook is a mechanical device used to lift and move heavy objects safely. It is typically made of strong materials like steel and is designed to attach to cranes, hoists, or other lifting equipment. The hook's shape allows it to securely hold loads, preventing them from slipping during transportation. Lifting hooks come in various types, including safety hooks, which have a locking mechanism to prevent accidental release, and clevis hooks, which can be easily attached to chains or slings. Proper use and maintenance of lifting hooks are essential to ensure safety in lifting operations.
