Crane Load Test Water Bags
Wear Resistant Flexible Fabric with Accurate Load Capacity and Quick Deployment
Water Weight Bag is a flexible temporary load testing system engineered for proof load testing, functional verification, and capacity assessment of marine cranes, deck cranes, davits, hoists, lifting appliances, and other load-bearing equipment. It uses controlled water filling to generate a predetermined testing load, providing a practical method for applications where conventional steel or concrete test weights are difficult to transport, position, store, or adjust.
Product Overview
The system is designed around the principle of converting a measured quantity of water into a controlled temporary load, allowing the testing team to establish progressive loading conditions according to the approved engineering procedure. The main body is manufactured from high-strength PVC or reinforced PVC-coated fabric selected for water containment, tensile performance, flexibility, and resistance to normal industrial handling.
Case Study: Water Weight Bag Testing for a Deck Crane
A commercial shipyard in South Korea was completing commissioning work on a newly installed deck crane fitted to a 38,000 DWT bulk carrier. The crane had a rated lifting capacity of approximately 40 tons and was scheduled for final operational verification before the vessel was released for service.
The Water Weight Bag system was selected as the temporary test load. The bags were delivered in an empty folded condition and transported to the vessel using the shipyard's normal material-handling equipment. The progressive loading procedure allowed intermediate inspections to be performed without removing and replacing heavy test weights.
