The invention provides a gantry crane structure which comprises a first vertical rod unit, a second vertical rod unit and a cross beam unit, the first vertical rod unit and the second vertical rod unit are arranged in a spaced mode and jointly support the cross beam unit, a rotating shaft is arranged in the first vertical rod unit, the first vertical rod unit comprises an upper portion and a lower portion, and the upper portion and the lower portion are arranged in a staggered mode. When the lower portion is fixed, the upper portion can be driven by the rotating shaft to rotate along with the rotating shaft, and when the upper portion rotates, the cross beam unit and the second vertical rod unit rotate with the axis of the first vertical rod unit as the axis. The method has the advantages of being reasonable in structural design, good in economic benefit, small in limitation of skylight points and flexible in construction.
