Water Filled Water Weight Bags for Crane Load Testing

Introduction‌
Water Weight Bags are innovative hydraulic load-testing solutions designed to replace traditional solid weights during crane certification and structural integrity tests. These collapsible, water-filled systems offer enhanced safety, efficiency, and cost-effectiveness for proof load testing across industries such as construction, offshore operations, and heavy equipment maintenance‌.

Key Features & Advantages‌

1. Safety-Centric Design‌

• Lifting sets are structurally separated from water bags to prevent systemic failure (safety factor ≥6:1 per drop tests)‌.
• Complies with ‌LEEA 051‌, ‌EN 1492‌, and ‌ASME B30‌ standards‌.

2. Operational Flexibility‌

• Modular Capacity‌: Configurable from ‌1 to 110 metric tons‌ with customizable low-height options for restricted spaces‌.
• Rapid Deployment‌: Fills/drains in minutes using high-pressure PVC/TPU hoses with camlock valves‌.

3. Quality Assurance‌
