Gangway load testing water weight bags can be used for the load testing of gangways, accommodation ladder, small bridges, platforms, floor, and other long structures.
Our standard gangway test water bags are 650L and 1300L capacity. For the larger gangways and small bridges can be tested with our Deck & Floor Water Bags. We also can make other size and shape load test bags upon the clients’ special request.
DOOWIN gangway load test water bags are made of heavy-duty PVC coating fabric material. Each gangway load testing bags equip with one filling valve, one discharge valve, and one air-relief valve. The discharge valve can be controlled by one rope. There are some handles at both sides. The worker can fix the water bag test weights by these handles.
