75 Tons Heavy Duty Crane Proof Load Bags Reinforced Seams Superior Tear Resistance

Economical Alternative to Solid Calibration Weights
Water bags eliminate the need for costly steel or concrete test weights, offering a reusable, adjustable, and cost-effective solution that adapts to a wide range of load requirements.

Compliance with International Testing Standards
Manufactured to meet or exceed standards such as OSHA, ASME B30.10, and EN 13135, ensuring the bags are suitable for certified crane testing and inspection programs.

Versatile for Multiple Load Testing Applications
Beyond cranes, these bags are also ideal for testing hoists, winches, lifting frames, and even structural load testing, thanks to their customizable size and capacity options.

Low Maintenance and Easy Cleaning
The smooth PVC surface resists dirt and algae buildup, allowing quick rinsing and cleaning. Regular maintenance is limited to visual inspections and valve checks, extending operational lifespan.

Accurate Load Application
Our bags allow gradual filling for precise, controlled load application during crane testing, reducing stress on equipment and ensuring compliance with test protocols.

Customizable Capacities and Shapes
We manufacture water bags ranging from 1 ton to over 100 tons capacity, with custom dimensions available to meet specific crane load test requirements.

Lightweight and Portable When Empty
Compared to solid test weights, our empty water bags are easy to handle, transport, and store, significantly reducing logistics costs.

Quick Setup and Deployment
Designed for fast installation with minimal manpower, our water bags can be prepared for testing within minutes, saving valuable project time.

Q1: What are crane load test water bags used for?
A1: They are used to apply precise, controlled loads during testing and certification of cranes, hoists, lifting equipment, and structural components to ensure safety and compliance with industry standards.

Q2: How do water bags compare to traditional solid weights for load testing?
A2: Water bags are more portable, adjustable, and cost-effective. Unlike solid weights, they can be filled onsite to the exact load needed and are easier to transport and store when empty.

Q3: What materials are water bags made from?
A3: Typically, they are constructed from high-strength, multi-layer reinforced PVC fabric combined with polyester mesh to ensure durability, flexibility, and resistance to punctures and abrasion.

Q4: How do you fill and drain the water bags?
A4: Water bags feature large, corrosion-resistant valves that allow rapid filling and draining using standard water hoses or pumps, significantly reducing setup and teardown time.
