Water Weight Bags are precision-engineered proof load testing devices designed for lifting appliances that require gradual load application, traceable load accuracy, and simplified logistics. Unlike fixed solid weights, Water Weight Bags utilize controlled water filling to incrementally increase load, allowing operators to monitor structural behavior at every stage.
In 2024, a major deep-water port in Oman conducted a comprehensive commissioning program for a newly built 65-ton gantry crane designed for container handling in high-temperature marine environments. Traditional counterweight blocks were not an option due to limited truck access and operational restrictions in the quay area.

The load accuracy typically falls within ±1% when using standard calibrated flow meters. For high-precision projects, digital flow measurement systems can improve accuracy further.
Yes. The TPU-coated structural fabric is engineered for thermal stability, UV resistance, and salt-spray durability.
