5 Tons Durable PVC Load Test Bags Wear UV Seawater Wear Resistant Easy Cleaning

Combining portability, accuracy, and safety, Crane Load Test Water Bags are trusted worldwide for verifying lifting capacities. They use water as a safe, controllable load medium, enabling step-by-step weight increase to the target load. When not in use, they fold down for compact storage, saving valuable space. Their robust construction ensures long-term performance in demanding industries.

• Superior Load Capacity and Accuracy
  Crane Load Test Water Bags are engineered to withstand extremely high loads, with capacities ranging from a few hundred kilograms up to several tons. Their precision design ensures consistent load distribution, providing highly accurate load test results for cranes and lifting equipment.
• Premium Grade Reinforced PVC Fabric
  Constructed from multiple layers of industrial-grade PVC with polyester reinforcement, these bags offer exceptional tensile strength and resistance to tearing or punctures, even under harsh working conditions.
• Advanced Leak Proof Welding Technology
  The seams are fused using heat-welding or RF (radio frequency) welding techniques, creating airtight seals that prevent water leakage during extended testing periods, ensuring safety and reliability.
• Rapid Fill and Drain Valves
  Equipped with large-diameter, corrosion-resistant valves designed for fast water filling and draining. This reduces setup and dismantling time on site, improving operational efficiency.

• Crane Load Testing and Certification
  Water bags are widely used to perform static and dynamic load tests on various types of cranes, including tower cranes, mobile cranes, and overhead cranes. By simulating actual lifting loads, they ensure cranes meet safety standards and regulatory compliance before operation.
• Hoist and Winch Load Testing
  Ideal for testing the load capacity and structural integrity of hoists, winches, and lifting gear. The flexible nature of water bags allows precise adjustment of test loads to match equipment specifications.
• Structural Load Testing for Bridges and Buildings
  Water bags serve as controlled, adjustable weights to test the load-bearing capacity of bridge sections, beams, floors, and other structural elements, enabling engineers to assess safety margins and durability.
