GB/T 31051-2025

This standard specifies the design, performance, and safety requirements for anchoring devices used to secure cranes during both operational (in-service) and stationary (out-of-service) conditions, including exposure to wind and seismic events. It is applied in the crane manufacturing and heavy lifting industries, particularly for tower cranes, gantry cranes, and ship-to-shore cranes, to prevent unintended movement or toppling. The standard guides engineers in designing reliable anchoring systems and assists procurement professionals in specifying compliant equipment for construction sites, ports, and industrial facilities.
