Certificates and Qualifications:
Testing and Certification
Before leaving the factory, the equipment needs to undergo strict tests, including performance tests (lifting, luffing, and slewing movements with rated and overload loads), emergency stop confirmation, manual brake release tests, limit switch confirmation (under no - load conditions), and insulation resistance measurement. The test records of each item will be submitted to users to ensure reliable product performance.
Company Certifications
