Advanced Multi Layer Fabric Technology
The bag body integrates multiple reinforcement layers, enhancing puncture resistance and fatigue strength. This structure ensures stability during repeated filling cycles and heavy lifting conditions.
Temperature Adaptability
Materials maintain flexibility across a wide temperature range, from cold offshore climates to tropical shipyards. Crack resistance and coating stability ensure long service life.
Optimized Filling/Draining System
Large diameter valves accelerate filling and draining, reducing operational time. Transparent level indicators assist operators in precise load monitoring.
Compact Storage Design
Foldable construction reduces storage footprint dramatically compared with steel weights, ideal for offshore logistics.
Applications
Dry Dock Testing Operations
Used during ship repair periods to verify onboard cranes without removing equipment.
