Where do I get the water?
Water supply is generally from a hydrant system, pumped out of a reservoir/body of water or a water truck supplied by customer.
Where do I dump the water?
If allowed water may be dumped in the immediate vicinity of the test or channeled/pumped to it's original source, or a drainage system.
How many gallons of water do I need to fill the bag?
Water generally weighs 8.34lbs/gal (fresh) and 8.4lbs/gal (salt). Given the actual weight of the bag, you can determine the remainder by dividing the total weight requirement by the weight of water above.
What about environmental concerns when dumping the water?
Please have a look at the different programs we have in place on our environmental page at http://waterweightsinc.com/en/environment.html. You may also ask your representative to supply our standard environmental documentation when asking for a quote.
Can I just set the bags on the ground?
We do not recommend setting our standard suspended water bags on the ground as a practice. We however, supply specially designed bags that are suited to this application.
Can I just transfer the bag to another crane when filled with water?
This is possible when using our specialist sit down bags during testing.
How much lead time do I need to give if I have a load test coming up?
Our standard requirement is 2 weeks for test that do not exceed 200 tons. For higher capacity tests, lead times will be specified in your quotation.
What if I don't have enough headroom to use the water bags?
We have developed alternative rigging arrangements and bag shortening techniques using specialized beams to address headroom challenges. Please talk to your local rep, if you have any headroom challenges.
How long will it take to fill and dump the water from the bags?
At standard fire hydrant pressure (approximately 240 gallons/minute), we can fill the bags on average at a ton (2,000lbs) per minute. Standard emptying time is about 2.5 tons (5000lbs) per minute dependent on distance to discharge location.
Is your equipment tested/certified?
The bags have a physically proven (type tested) factor of safety in excess of 6:1 and proof load tested to over 2:1 prior to being taken into service. They are also certified and type approved by the American Bureau of Shipping and tested and manufactured to ISO9001-2008. Click here to watch video of test.
How do you measure the weight in the bag?
The load is measured by using either a certified flow meter that registers the water in gallons when filling the bag(s) or by using a certified load cell with indicator that measures the actual weight just below the hook.
How often are the bags tested and repaired?
After each job, upon return to our premises.
What are the hose sizes attached to the bag?
Filling is achieved through a standard 2.5" hose, and a 4" drain line which may be supplied with or without a valve for draining. Please talk to your local representative about fittings and valves per test requirements.
