The invention discloses a gantry crane with an anti-falling function. The gantry crane comprises a gantry frame, a climbing ladder and an anti-falling device, the climbing ladder is mounted on the portal frame and grab rails are arranged on two sides; the anti-falling device is mounted on the grab rail through the clamping cavity and is connected with a climber through a safety rope; the anti-falling device comprises a shell, a plurality of roller assemblies and an unlocking assembly. The multiple roller assemblies are installed on the shell at intervals in the circumferential direction to form a clamping cavity. The unlocking assembly is installed on the shell and matched with the roller assembly, and the safety rope is connected with the unlocking assembly; the unlocking assembly is located at the first position in a natural state or under the downward pulling force of the safety rope, and then an included angle is formed between the rolling direction of part of or all the roller assemblies and the axis of the grab rail. The anti-falling device has the beneficial effects that when the anti-falling device is used, unlocking of the locking state can be achieved only by pulling up the safety rope, and the anti-falling device can be conveniently used by a worker during climbing.
