FAQ
1. Can underwater lift bags be used in conjunction with other lifting equipment?
Yes, underwater lift bags can be used in combination with other lifting equipment to lift heavier objects.
2. How do you choose the right size lift bag for a specific lifting operation?
The size of the lift bag needed will depend on the weight of the object being lifted. It is important to choose a lift bag with a lifting capacity that exceeds the weight of the object.
3. Are there special considerations for using underwater lift bags in cold water?
In cold water, it is important to ensure that the lift bag material is suitable for low temperatures and that the inflation mechanism is not affected by cold conditions.
4. Can underwater lift bags be used in strong currents?
It is best to avoid using underwater lift bags in strong currents, as this could make it difficult to control the lift operation.
