The disclosure relates to a container inspection system, a port facility, and a box inspection method. The container inspection system comprises a quay crane (100), a sensor, and an inspection device (200), wherein the quay crane (100) comprises an inspection platform (102) and a hoisting component (101), the hoisting component (101) being configured to hoist a container (300) and transport the container (300) to the inspection platform (102); the sensor being disposed on the inspection platform (102), for detecting whether the container (300) arrives at the inspection platform (102); and the inspection device (200) being disposed on the inspection platform (102), for performing scanning inspection on the container (300) arriving at the inspection platform (102). The port facility comprises the container inspection system. The container inspection system of the present disclosure occupies a small floor area, and performs scanning inspection during loading/unloading, so that in-yard inspection may be avoided, thereby effectively shortening the circulation time of a container at a port, and providing high circulation efficiency; and effectively preventing dangerous prohibited articles from entering a yard, and providing high safety.
