The continued development of WATER WEIGHTS® water filled proof load bags has increased greatly the practicability, economy and safety of providing proof load testing on cranes in power plants, general industry, construction and marine operations.
During transportation and staging the bags with load cells weigh approximately 2% of its rated load keeping freight costs, storage space, floor loading and especially manpower to a minimum.
The load is always measured accurately with a certified loadcell or flowmeter, so exact weight variations required during test is always achieved by simply filling or dumping the bags.

There have been several serious accidents during proof load testing involving Sub Standard Equipment which was simply not designed for the physical demands of proof load testing.
The use of WATER WEIGHTS® water filled proof load bags for proof load testing is recognised world wide as the most effective and safest solution.
