T/CPASE MT012-2021 Bridge-type crane metal structure crack damage resistance impedance monitoring method
Basic Information
Scope
Main technical content: This document specifies the monitoring principles and methods, monitoring instruments, monitoring conditions, monitoring procedures, evaluation of monitored structures, monitoring records and reports, and handling of abnormal situations for piezoelectric impedance monitoring of crack damage in the metal structures of bridge-gate cranes. This document is applicable to bridge-gate cranes operating in general environments, but not to those used in environments with flammable and explosive substances, combustible gases, dust, corrosive gases, nuclear radiation, or toxic gases. The piezoelectric impedance monitoring of crack damage in the metal structures of other types of lifting machinery can be carried out in accordance with this document.
