Load / Drop Test Hooks

Load and Drop Test Hooks

Load and drop test hooks are used for proof load testing and functional verification of lifting and life-saving equipment. These hooks allow controlled release during testing procedures to simulate real operational conditions. They are commonly used by service stations, inspection bodies, and testing facilities.

Key Applications

• Proof load testing
• Dynamic drop testing
• Type approval testing

Testing Standards

• IMO requirements
• Classification society guidelines

Equipment Considerations

• Accurate load capacity
• Repeatable release performance
• Controlled test conditions

These hooks are designed to deliver consistent and measurable performance during testing procedures, ensuring that equipment meets required safety and operational standards.

Looking for a release hook for drop testing?

If your project has moved from general research to specifying hardware, PRD Hook’s drop testing application page outlines on-load release options, actuation choices, SWL ranges, and suitable product series for controlled and repeatable test setups.

Selection factors for load and drop testing

Drop testing places unusual demands on a release hook because the release event must be repeatable, measurable, and clean. The hook should match the required safe working load, release under the expected load condition, and avoid adding side force or unwanted rotation to the test object.

Common selection factors include the maximum test mass, release height, number of cycles, triggering method, fixture geometry, reset time, and whether the test requires manual, electric, pneumatic, or hydraulic actuation. For laboratory and production test rigs, consistency across repeated cycles is often more important than basic lifting capacity alone.
