Description
Hongruntong Marine crane load testing water bags are flexible, high-capacity proof load devices specifically developed for marine cranes, offshore lifting systems, and heavy industrial hoisting equipment. Constructed from multi-layer reinforced PVC fabrics, these bags deliver excellent tensile performance while remaining lightweight when empty.
Their modular configuration allows easy handling and rapid deployment. Integrated safety valves, reinforced lifting lugs, and calibrated filling systems ensure accurate load simulation. These water bags significantly enhance testing safety while lowering transport and operational costs.
Case Study – Floating Crane Commissioning
During commissioning of a 200-ton floating crane in a Middle Eastern shipyard, traditional test weights posed transport challenges. Hongruntong supplied a set of interconnected water bags totaling 220 tons.
The modular setup allowed staged loading. Testing finished ahead of schedule, reducing crane commissioning time by two days. Engineers highlighted improved safety margins and simplified logistics.
