越えないようにする装置である。(Prior art) During a periodic inspection of a nuclear power plant, when a fuel assembly is being extracted from a nuclear reactor using a refueling crane, the fuel assembly gets caught in another fuel assembly and the fuel is removed. Aggregates may interfere with each other. To mitigate or avoid this interference, air balancer devices or load monitoring devices are mounted on refueling cranes. This air balancer device is a device that automatically stops the hoist while mitigating the impact when interference occurs between fuel assemblies using air cylinders, thereby preventing damage to the fuel assemblies. The load monitoring device is a device that detects the load of the fuel assembly when interference occurs between the fuel assemblies and immediately stops the hoist to prevent the load from exceeding the protection load of the fuel assembly.
