Recently, ZPMC, a subsidiary of CCCC, led the revision and publication of two international standards, ISO 9374-4:2024 and ISO 9374-1:2024, regarding the information to be provided by crane suppliers and users. This follows ZPMC's 2021 release of three international standards for cranes.

These newly revised standards update the versions initially released in 1989, incorporating modern crane design methods, intelligent technology, and critical safety information. They are set to enhance global commercial collaboration and technical exchanges between crane manufacturers and users.
