Standard Weight Calibration Container for Accurate Load Testing
Product Overview
The Standard Weight Calibration Container is a specialized, high-precision testing solution designed for the calibration and verification of container weighing scales, weighbridges, and overload/unbalanced load detection devices. As global logistics regulations (such as VGM – Verified Gross Mass) become increasingly strict, ensuring the accuracy of container weighing is critical for transportation safety.
This calibration container provides a reliable, traceable measurement standard. It effectively resolves common issues in container weighing by offering a stable, high-mass reference point, thereby guaranteeing the accuracy of testing equipment and ensuring the safe transportation of freight across rail, road, and sea networks.
Key Features & Engineering Excellence
-
Collaborative R&D: Jointly developed with the Scientific Research Institute of China Railway Shanghai Group Co., Ltd. This partnership ensures the calibration box meets rigorous engineering standards, improves measurement accuracy, and provides solid technical support for safe container transport.
-
Traceability & Reliability: Provides a high-precision measurement standard that ensures the accuracy and long-term reliability of your weighing equipment, making it ideal for periodical verification and legal metrology compliance.
-
Optimized Internal Structure: The calibration container features a rationally designed internal layout. The standard weights are securely integrated and evenly distributed to simulate real container loads, making the unit highly convenient to use, transport, and maintain.
-
Versatile Configurations: Available in standard 20-foot and 40-foot ISO container dimensions to suit various sizes of weighbridges and handling equipment (e.g., reach stackers, gantry cranes, and rail weighbridges).
Proven Field Application
The system has been successfully deployed and accepted on-site at major logistics hubs, such as the Shanghai Beijiao Freight Yard. It is widely trusted by railway operators and port authorities to validate their weighing infrastructure and prevent costly overweight penalties or dangerous unbalanced loads.
