At Holloway, water bag testing provides a safer, more economical, and less time-consuming alternative to solid weight testing for proof testing cranes, lifeboats, structure strength, and other applications.

Our water bag testing method is safer because water bags are less likely to tip over or collapse, and they can be easily moved and positioned, reducing the risk of accidents. Water bag testing is also more economical because water bags are less expensive to purchase and transport, and they can be reused multiple times. Finally, water bag testing is much faster than solid weight testing because water bags can be filled and emptied quickly, and they can be stacked to test multiple loads simultaneously.
