Crane Load Test Water Bags High Load Capacity Easy To Fill Drain Reusable

Load Testing Water Bags are engineered for mega-scale projects requiring extremely high proof loads and precise structural verification. These custom-designed systems are suitable for heavy industrial cranes, offshore lifting appliances, large bridge spans, and port or shipyard infrastructure. By using water as a controllable load medium, these bags allow precise incremental loading while eliminating the logistical, safety, and cost challenges associated with massive steel or concrete test weights.

Each bag is manufactured from multi-layer, high-tensile technical fabrics reinforced with heavy-duty webbing and specialized seam construction to handle extreme hydrostatic pressures. Lifting points are strategically reinforced, and customized attachment configurations are available to meet project-specific load distribution requirements.

A leading port authority required proof load testing of newly installed ship-to-shore cranes rated up to 400 tonnes. Traditional steel test weights were impractical due to extreme size, handling complexity, and limited dockside space.

Hongruntong Marine provided a fully customized fleet of ultra-high-capacity Load Testing Water Bags engineered to carry loads exceeding 50 tonnes each. The modular system allowed multiple bags to be combined safely to reach the required total test load.

During testing, bags were delivered empty, deployed using site cranes, and incrementally filled with seawater. Engineers monitored crane performance, structural deflection, and load distribution at every stage. The client reported exceptional safety, operational efficiency, and reduced project risk.
