Water weight bags are simple and safe water filled crane test weights designed to provide proof load testing instead of traditional solid load test weights.
DOOWIN load test water weight bags are designed for proof load testing the lifting equipment and structures that request proof load weight testing. When it’s newly finished, or periodic check or maintenance. Such as crane load testing, beam load test, lifeboat davit load test, derrick load testing, overhead crane load test. So, this water-filled water weight bags offer one kind of innovative crane load test weights solution. Most noteworthy, it has the advantages of Safety, Economy, Convenience, High Efficiency.

Proof load test water weight bags is one crane load test weights system including proof load bags and all its accessories.
Moreover, these crane load test bags are designed that the lifting set is separate from the water bag body.
As a result, the failure of anyone’s webbing element will not result in the failure of the lifting set nor cause a local overload of the weight test water bags.
The below specification is a common sizes proof load bag. In addition, we also make other size and other capacity load test water bags upon request.

DOOWIN offers water-filled proof load bags used for the low headroom bridge crane load test when the testing operation has low headroom.
Low-headroom water-filled proof load bags have a short height. So, it is a very flexible proof load test way where headroom is restricted. Each lifting point only can hang one low headroom water-filled proof load bag.
