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

Ultra High Load Capacity and Scalability

Designed for the most demanding industrial and offshore projects, these water bags can be combined to achieve mega-scale loads exceeding hundreds of tonnes. Reinforced structures and precise load distribution ensure safe, predictable behavior under extreme hydrostatic pressures, providing confidence for engineers during critical proof load tests.

Customizable Configurations for Project-Specific Requirements

Hongruntong Marine offers fully customized solutions, including bag dimensions, lifting point arrangements, and modular connection systems. This allows adaptation to unique project constraints, such as unusual crane geometries, dock layouts, or offshore platform limitations.

Extreme Environmental Durability

Bags are constructed from advanced multi-layer technical fabrics resistant to UV, seawater, hydrocarbon exposure, and temperature extremes. Seams and lifting points are reinforced to maintain structural integrity under repeated use in challenging environments, including offshore, port, and high-exposure construction sites.

Precision Control and Safety Systems

Integrated filling and draining systems allow fine control of applied loads in staged increments. Reinforced attachment zones and multiple lifting points provide redundancy and operational safety. The water medium naturally mitigates shock loads, reducing risk for personnel and equipment during mega-scale testing operations.

Applications

Port and Shipyard Mega Crane Certification

Used for proof load testing of ship-to-shore, quay, and gantry cranes rated up to several hundred tonnes. The bags allow precise load application without massive steel weights or permanent ballast.

Offshore Platform Lifting Appliance Verification

Ideal for heavy-duty offshore cranes, subsea lifting frames, and winches. The water bags perform reliably in harsh marine environments, enabling compliance with classification society standards and project-specific load requirements.

Large Scale Structural Load Testing

Applicable to bridges, heavy industrial platforms, and temporary construction structures where extremely high loads must be verified. Modular configuration enables precise staging and distribution of massive loads safely.
