Description

Water Weight Bags High Capacity Leak Proof Rapid Filling Lightweight Durable

Description

Crane Load Test Water Bags are engineered flexible load testing devices designed for proof-load testing of cranes, davits, winches, and lifting structures in marine and industrial environments. Manufactured from high-strength PVC-coated woven fabric with reinforced seams, these water bags provide a safe, controllable alternative to traditional solid test weights.

Typical capacities range from 1 ton to over 100 tons depending on project requirements. The lightweight empty structure allows easy transportation and deployment, while the filling system enables gradual loading for precise calibration. UV resistance, abrasion protection, and excellent tensile strength ensure reliable performance even in harsh offshore or shipyard conditions.

These water bags significantly reduce logistics costs, enhance operational safety, and simplify load test procedures for shipyards, ports, offshore platforms, and heavy industry facilities.

Case Study – Offshore Supply Vessel Crane Test

A Southeast Asian offshore service company required annual certification of a 50-ton deck crane installed on an offshore supply vessel. Transporting solid test weights offshore was costly and logistically complex.

Hongruntong Marine supplied modular water load bags with calibrated flow meters. The bags were filled directly using seawater, allowing controlled incremental loading. The entire test was completed within one day, reducing downtime by 40%.

Operators reported excellent handling, stable load behavior, and easy draining. The system has since become their standard annual testing solution.

Features

High Strength Structural Fabric
The load bags are produced from industrial-grade polyester base fabric coated with marine-grade PVC elastomer. This construction ensures exceptional tear resistance, minimal elongation under load, and strong fatigue durability. Reinforced webbing belts distribute stresses evenly, preventing localized overstress during lifting operations.

Controlled Progressive Loading Capability
Unlike solid weights, water load bags enable gradual load increase. Integrated filling valves, calibrated flow meters, and pressure relief systems allow operators to precisely control load increments. This improves testing accuracy while significantly reducing sudden shock loading risks.

Abrasion and Environmental Resistance
The outer layer incorporates UV inhibitors and abrasion-resistant coating. The bags maintain flexibility in low temperatures and resist degradation from saltwater, oils, and sunlight exposure. This extends operational lifespan even in offshore environments.

Operational Convenience and Storage Efficiency
Empty bags are foldable and lightweight. They require minimal storage space and can be transported easily to remote offshore sites. Quick-connect hoses and standardized shackles simplify installation.

Applications

Shipyard Crane Certification
Water load bags are widely used for commissioning tests of gantry cranes, jib cranes, and floating cranes during ship construction or repair.

Offshore Platform Maintenance
They enable periodic proof load testing of platform cranes without requiring heavy transport vessels for solid weights.

Port Equipment Verification
Harbor authorities use them for scheduled inspection of quay cranes, davits, and lifting beams to meet regulatory compliance.
