Erecting machine formal trial before lifting cranes and equipment safety inspection

overhead gantry craneerecting machine before formal lifting, try hanging the work must be organized. As a test crane, load must be graded, but also overload test must be carried out, how many super-appropriate, general lifting industry standard of 30%. However, due to larger tonnage  hoist gantry crane  hoisting works, by design, technology, materials, and machine safety sector participation overloading agreed quantity, it must be stressed overload test must be carried out. Try hanging examined several indicators must be clear, such as deflection, roll, midline, etc.; while lifting must be clear after the completion of trial conclusion (whether it meets the design requirements).
All machines and lifting equipment rack according to design drawings required after installation, first project organized by the Ministry for bridging machine and lifting equipment to conduct a comprehensive and detailed examination; final quality inspection department for acceptance, steel crane  who found that deficiencies must be timely reinforcement or rework, acceptance only after the trial lift and lifting operations and lifting equipment inspection tables fill the archive as a machine a file based data.
