Water Weights

Water bags for load testing

Load test with Water Weights Bags

Load tests of items with a very large load weight are often carried out with Water Weights Bags.

Water Weights Bags are specially designed containers that are filled with water to achieve the desired load weight. Since water is available everywhere, you only need to transport and store the light flexible material from which the water bags are made. Our Water Weights Bags typically weigh less than 2% of the total load weight, the remaining 98% is made up of water.

The method makes it possible to test everything from aircraft decks, lifting beams, cranes and other lifting equipment, to bridges of lifeboats. The technology is simple, safe and adjustable, so it can be used in many places. Indoors, outdoors, onshore, offshore, at your own location or on the other side of the globe.

The Water Weights Bags are often used for load tests and certifications of lifting equipment in offshore and maritime environments.

We have water bags in the sizes 1-2-5-10-12-20 and 35 tons

We hereby have a solution for all load test challenges!
