Crane Testing Water Bags
Hydro-Wates rents crane proof load testing water bags in capacities ranging two (2) metric tons up to thirty five (35) metric tons. In certain applications, these water bags can be clustered together and stacked, with standard rigging hardware, to achieve test loads of up to 500 metric tons, without the need of spreader beams.
With our extensive inventory of rental water bags and rigging hardware, you can rent all of the equipment necessary to perform your load test from one supplier. We can ship this equipment anywhere in the world packed in special shipping containers that we supply. Our rental fleet of crane testing water bags includes the following sizes: 2 Te, 5 Te, 12 Te, 20 Te and 35 Te. All of our water bags are rated in metric tons.
Our water bags have undergone extensive design verification and inspection prior to being released for field use. The minimum design safety factor for our water bags is 6:1 and each water bag is proof load tested to its rated working load capacity following assembly. All of our water bags are manufactured in accordance with EN ISO 9001:2008.
Advantages of Using Crane Load Testing Water Bags
- Ease of Handling. Since water bags are constructed from a light weight and pliable PVC fabric, they can be rolled up and packaged into containers that allow for economical shipping to your worksite – worldwide. The packaged weight of water bags is approximately 1% of its weight when filled with water.
- Controlled Application of Test Load. Application of test loads occurs gradually as the water bag is filled with load water. This prevents shock loading and allows for the early identification of technical problems with the equipment being tested. It is also possible for the operator to stage up to the final proof-load using intermediate hold points and test hoisting/braking capability of equipment prior to reaching full test load.
- Verification of Test Force. Accurate selection of test loads can be achieved using calibrated load cells or water meters. This allows for an infinite number of test loads to be achieved to meet equipment specific requirements. All of our load cells and water meters are provided with calibration certificates which are renewed annually.
- Controlled Release of Test Fluid. Release of test fluid is performed by draining water from the water bags, avoiding the need to lower the test load in critical or hazardous areas.
- Compact Size for Shipping. Because of their compact size, water bags and load measurement equipment can, in many cases, be transported by pick-up truck and small commercial trailers.
- Acceptance by Certifying Authorities. Water weights are accepted for proof load testing by US Occupational Health & Safety Administration, UK Health & Safety Executive, American Bureau of Shipping, Det Norske Veritas, Lloyds Register, and other classification and certification organizations.
