The invention relates to a novel direct-drive gantry crane, which is directly driven by a linear motor in planar motion. The device comprises a longitudinal rail provided with a longitudinal linear motor secondary, a longitudinal moving portal frame provided with a longitudinal linear motor primary, a rail provided with a transverse linear motor secondary and a transverse platform provided with a transverse linear motor primary, longitudinal supporting wheels are arranged at the bottom of the moving portal frame, and transverse supporting wheels are arranged at the bottom of the transverse platform. The longitudinal rails are respectively mounted on the left side and the right side of a longitudinal channel of the gantry crane; the linear motor secondary is mounted on the rails; according to the technology, a movement mechanism of the gantry crane can be simplified, the operation efficiency is improved, faults and maintenance are reduced, and the operation cost is reduced. Therefore, the gantry crane can be better applied.
