Proof Testing Water Bags

All our water bags are made of high quality PVC coated polyester material fabric. Water bags are used for testing cranes and many other types of lifting structures and applications. The ‘raindrop’ design of the water bags ensures that the weight is evenly distributed over the entire water bag. As a result, most water bags have a safety factor of 6:1. In addition to the regular ‘standard’ type water bags, there are also ‘low headroom’ type water bags. The ‘low headroom’ version is specially designed for testing in places where lifting height is limited.
