150T Capacity Load Testing Water Bags with PVC Fabric Reinforced and UV Resistant for Industrial Proof Load Testing

Hongruntong Marine Load Testing Water Bags are specialized flexible test weights engineered for lifeboat and davit testing applications. These bags meet the unique dimensional and procedural requirements of survival craft certification as mandated by international safety conventions and classification societies.

Designed for proof load testing at 1.1 times the maximum working load, these water bags feature geometries specifically tailored to fit within standard TEMPSC designs. This allows for accurate simulation of weight distribution and permits observation of craft hull structure deflections and on-load release mechanism operation under realistic conditions.

The material specification prioritizes clean handling with complete absence of substances that could stain or contaminate survival craft interiors. The external fabric features an anti-soiling compound to prevent color or plasticizer transfer. Constructed with fully welded perimeter seams to eliminate leakage potential, each bag includes a dedicated fill hose with quick-connect camlock fittings.

• Lifeboat Hull Conforming Geometry
  Flexible envelope conforms to internal contours of lifeboat hulls, ensuring test load is transferred across broad contact area for accurate service loading simulation.
• Clean Handling Fabric with Zero Residue Transfer
  PVC formulation with high-molecular-weight plasticizer system and polyurethane topcoat prevents surface tackiness and residue transfer to sensitive equipment.
• Integral Lift Point Access Ports
  Reinforced access ports align with lifting bridle penetration locations, allowing rigging connection from outside the craft and reducing setup time.
• Color-Coded Capacity Identification System
  Visual identification system using colored fabric, lifting eye webbing, and storage bags prevents deployment errors and facilitates inventory management.

• Passenger Vessel Lifeboat Davit Testing: Streamlines SOLAS Convention compliance testing, reducing time per station to under one hour and eliminating material handling logistics.
• Offshore Installation TEMPSC Testing: Specifically sized for Watercraft, Harding, and Norsafe product families, ideal for remote locations with severe deck space constraints.
• Rescue Boat Davit Certification: Low-profile design distributes test load across hull bottom, eliminating point loading that can damage boat structure.

• Specialized Regulatory Knowledge: Deep understanding of international conventions, classification society rules, and flag state requirements.
• Tailored Bag Sizing: Database of internal dimensions for common lifeboat models ensures optimal fit and accurate weight distribution simulation.
• Lightweight Portability: Empty bags weigh less than 20 kg for 5-tonne capacity, enabling single-person transport through vessel accommodations.
• Surveyor Acceptance: Widely recognized by major classification societies with comprehensive documentation packages meeting surveyor expectations.

• How is the water bag secured within the lifeboat to prevent movement during testing?

  The bag's conforming geometry and friction with interior surfaces prevent movement. For additional security, integral lashing points allow attachment to seat mounting hardpoints.

• Can the same water bag be used to test multiple lifeboats of different capacities?

  Yes, bags can be partially filled for lower test loads with provided calibration tables relating fill volume to suspended weight.

• What is the procedure for drying and storing the water bag after testing?

  After complete drainage, air dry thoroughly in well-ventilated area, then fold according to original crease pattern and store in protective bag in clean, dry location.

• Are these bags compatible with lifeboats equipped with on-load release mechanisms?

  Yes, specifically designed for compatibility with on-load release mechanisms, applying full test load through lifting bridle for proper operation verification.

• What is the maximum water temperature for filling bags in tropical waters?

  Rated for continuous service up to 60°C, well above typical fire main water temperatures in tropical regions (approximately 30°C).
