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.
