GB/T 31051.4-2016

This standard specifies the design, performance, and safety requirements for anchoring devices used to secure jib cranes during both operational (in-service) and non-operational (out-of-service) conditions, including exposure to wind loads. It is applied in the material handling and construction industries for jib-type cranes, such as tower cranes or luffing jib cranes, to prevent unintended movement or tipping during use or when parked. The standard ensures reliable anchoring in environments like ports, shipyards, or building sites where wind or other external forces could compromise crane stability.
