Load Test Water Bags Constructions
Load test water bags is one system including water bags body and all its accessories. The water bags are designed that the lifting set is separate from the water bag body. The failure of any one webbing element will not result in failure of the lifting set nor cause a local overload of the bag.
Each set load test water bags system comes ready with following accessories certificated:
— Master link and shackles, 6:1 safety factor, EN 1677 or EN 13889
— Polyester webbing lifting straps, round slings, 6:1 SF, compliance with EN 1492-1
— High quality filling and drain hose with valves and camlocks
— Several handles welded around the water bag body
— The marine rope with pulleys
How to choose the best quality water bags?
Type Certificated by Drop Test
Comply with LEEA 051
DOOWIN load test water bags are designed manufactured, tested and certificated in 100%
compliance with LEEA 051 guidelines. There are several key elements.
- Lifting set should separate from water bags. Comprised several elements should share
the load. Each element should be manufactured comply with relevant BS standard.
- The safety factor of each type and size water bags should be proven via drop
test to at least 6 times the working load limit.
- Every water bags should be verified via either inflation of the water bags to
pressure in the range to 0.25~0.5 bar and then visual check of welded seams
for integrity and no leakage, or via a proof (drop) test to at least 2 times the WLL.

Awesome to use DOOWIN buoyancy bags for our Aramco project. Its quality completely can be comparable with UK products.
We have confident with DOOWIN. They can help us with innovative solution, well prepared to accommodate to our request.
Proof Load Testing Service
DOOWIN provides proof load testing services to companies across the China & throughout the world.
We have highly trained and licensed professional engineering team. They can perform specific proof load testing tasks and projects.
Crane Proof Load Testing
All types cranes can be load tested using water bags. And water bags are very convenient for the low headroom or very tight areas of load testing. Water bags can be filled with water slowly. So the crane problems can be recognized and corrected prior to reaching the rated testing load.
Overhead Crane Load Testing
DOOWIN offer expert proof load testing services for the overhead crane and bridges crane, jib and gantry cranes using our certificated water bags. We can do proof load testing service for initial commissioning, after repairs and periodic inspects of cranes.
Lifeboat Davit Load Testing
For proof load testing lifeboat davit system, DOOWIN offer certificated professional load test water bags 1t~20t. The required proof load testing can be accurately applied to ensure compliance with applicable regulations and proper lifeboat davit testing.
Boat Lift Load Testing
Because of the special structure of boat lift, proof load testing using water bags is recognized as a safe, effective load testing method. Proof load testing is generally performed prior to initial use, after repair, periodically inspection.
Building Load Testing
DOOWIN offer proof load testing for the building construction using pillow shaped water bags. Our pillow water bags can well ensure the uniform weight distribution. We equip the certificated water meter to ensure exact load water inside water bags.
Lifeboat Load Testing
For lifeboat load testing, the small size water bags can be arranged inside the vessel to simulate passenger loading. The water weight can be controlled accurately by professional filling and discharge lifeboat water bags system from far place.
