Understanding Load Testing Water Bags

What Are Load Testing Water Bags?

Load Testing Water Bags are specialized, flexible containers designed to simulate heavy loads during proof load testing of lifting equipment. They are widely used for cranes, lifeboats, davits, winches, gangways, and offshore platforms to ensure safety and compliance with international standards.

How Do They Work?

Instead of using solid weights or steel blocks, Load Testing Water Bags are filled with water on-site to create the desired test load. This method is:

• Safer – Gradual loading reduces risk to equipment and personnel

• Cost-effective – No need to transport heavy solid weights

• Flexible – Multiple bags can be combined for higher capacities

• Easy to handle – Lightweight and compact for storage and shipping

Key Features of High-Quality Load Testing Water Bags

• Certified and Durable Materials: Made from high-strength PVC or reinforced polyester fabric

• Precision and Accuracy: Calibrated flow meters and load cells ensure accurate weight measurement

• Rapid Deployment: Quick-fill valves and strong lifting points for fast setup

• Wide Capacity Range: From a few tons to hundreds of tons for different applications

Why Choose Load Testing Water Bags Over Traditional Weights?

• Reduced Logistics Costs: Only water is transported on-site

• Minimal Storage Space: Foldable and compact when not in use

• Customizable Solutions: Sizes and capacities tailored to specific projects
