How to choose the right inflatable flexible jack ?
The choice of an inflatable flexible jack depends on several key criteria. It is important to clearly define your requirements beforehand to ensure an efficient and durable solution.
Here are the main factors to consider:
- The application shape : flat surfaces, circular areas, or complex geometries
- The required capacity : load to lift or pressure to apply
- The operating environment : temperature, chemicals, mechanical constraints
- The available space : some jacks are designed for very confined spaces
- The lifting height : the difference between the initial and final positions
In specific or complex cases, custom-made solutions are often the most suitable to ensure performance and safety.
