Using water bags for your proof load testing requirements has many advantages:

1.  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 – across the U.S. and worldwide. The packaged weight of water bags is approximately 1% of its weight when filled with water.

2.  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.

3.  Accurate selection of test loads can be achieved using force dynamometers or water meters.  This allows for an infinite number of test loads to be achieved to meet equipment specific requirements.

4.  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.

5.  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.

6.  Water bags 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.
