Crane Load Test Water Bags are innovative tools designed for proof load testing of lifting equipment, including cranes, davits, and winches. Made from high-strength PVC or TPU materials, they are lightweight when empty and easy to transport, yet capable of carrying loads from 1 ton to over 100 tons when filled with water. These bags allow gradual load application, ensuring accurate measurements and minimizing stress on the equipment. Their compact storage size, corrosion resistance, and quick setup make them a preferred choice for shipyards, offshore platforms, and construction sites.

• Reinforced Lifting and Handling Points
  Heavy-duty lifting loops or D-rings are integrated into the bag's design, reinforced with extra fabric layers and stitching, enabling secure rigging and safe handling during testing.
• Compatibility with Load Monitoring Systems
  Water bags can be used in conjunction with electronic load cells and sensors to provide precise, real-time load data, enhancing safety and documentation during testing.
• Chemical and Abrasion Resistance
  The PVC fabric resists degradation from exposure to oils, greases, acids, and solvents commonly found in industrial sites, ensuring the bag maintains integrity in tough environments.
• Custom Branding and Identification Options
  Manufacturers offer the option to print logos, serial numbers, and safety instructions directly onto the bag surface for easy identification, traceability, and compliance with client branding policies.

• Industrial Machinery Load Testing
  They are utilized in testing heavy machinery and equipment that require periodic load verification to maintain operational safety and compliance.
• Testing Temporary Structures and Scaffolding
  Water bags help verify the load capacity of temporary scaffolds, platforms, and worksite support structures before use.
• Testing of Lifting Accessories and Rigging Equipment
  Used to test shackles, slings, hooks, and other rigging accessories by applying precise loads to ensure compliance with safety standards.

• Over 30 Years of Professional Manufacturing Experience
  With three decades of continuous production and R&D, we have developed unmatched expertise in crane load testing technology. This experience ensures stable product quality, precise engineering, and the ability to handle highly customized client requests.
• Specialization in Load Test Solutions
  Focusing exclusively on load test water bags allows us to refine designs for maximum safety, efficiency, and durability. Every detail, from lifting point reinforcement to seam welding, is optimized for heavy-duty industrial use.
• Marine Grade PVC/TPU Fabric
  We use high-strength, abrasion-resistant PVC and TPU composite fabrics that offer excellent UV resistance, saltwater corrosion protection, and long-term durability, even in harsh marine or offshore environments.
• Advanced High-Frequency Welding Technology
  All seams are produced with high-frequency heat welding, creating strong, leak-proof joints that can withstand extreme loads without failure.
