In high-risk industries such as petrochemicals, energy storage, and hazardous operations, positive pressure containers play a critical role in protecting both personnel and equipment. Ensuring their structural reliability is essential. One of the most important validation steps is the lifting test, which verifies the strength and stability of the container under operational conditions. This test is also key for obtaining international certifications like DNV 2.7-1 and EN 12079.
Purpose of the Lifting Test
The lifting test serves several critical functions:
Testing Procedure
The lifting test typically follows these steps:

Conclusion
Lifting tests are a critical step in validating the structural safety of positive pressure containers. At TLS, all lifting tests are performed according to international standards, guaranteeing that every container delivered meets stringent safety and reliability requirements for high-risk environments.

Purpose of the Lifting Test
The lifting test serves several critical functions:
- Verify load capacity: Ensures that lifting points, base frames, and the overall structure can safely handle both rated and overload conditions.
- Check structural stability: Confirms that the container maintains its shape during lifting and that welds and connections remain intact.
- Support certification: Provides third-party testing evidence required for international standard compliance and customer assurance.
Testing Procedure
The lifting test typically follows these steps:
- Applying load: The container is lifted using cranes at specified angles, often around 45°, to simulate real-world lifting scenarios.
- Load levels: The applied load ranges from 100% to 125% of the safe working load to evaluate performance under overload conditions.
- Test duration: The container is held in the lifted position for several minutes to observe any structural shifts.
- Inspection points: Lifting points, base frame, welds, and overall structure are carefully checked for permanent deformation or damage.
Results and Applications
After testing, a third-party inspection report documents:
- Applied loads, lifting angles, and duration
- Any observed structural deformation or damage
- Final pass/fail evaluation

Lifting tests are a critical step in validating the structural safety of positive pressure containers.
