500kg Lifeboat Proof Load Testing Water Filled Weight Bag
Proof load water bag:
Proof load water bag is specifically designed to use water in place of traditional solid weights for loading test. This system allows for a much safer and practical method for load testing for most of the lifting equipment and load bearing structures, such as deck cranes, pedestal cranes, offshore cranes, and general purpose cranes.
Using water bags for your proof load testing requirements has many advantages:
1:Safe:The bags have a physically proven factor of safety in excess of 6:1 and are proof load tested to over 2:1 prior to being taken into service.
2: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 work site - across the China and worldwide from our service center in China. The packaged weight of water bags is approximately 1% of its weight when filled with water.
3: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.
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.
