The invention discloses a gantry crane used in tunnel construction, and relates to the gantry crane used in tunnel construction. In order to solve the problems that in the prior art, turnout hoisting of the current railway passenger dedicated line is carried out though adopting a crane, during hoisting, the turnout hoisting performed by using the crane in a tunnel is influenced by tunnel height and sites, and hidden danger is easy to happen to the finished product protection on a turnout and the safety of construction personnel; the crane is stayed in the tunnel, and cannot carrying out hoisting until completing the steel bar binding, so that the transportation cost is increased, the hoisting cost is increased, and the construction cost is increased; every time of hoisting and position alignment needs a long time, so that the construction period is influenced. The gantry crane comprises cross beams, an electric hoist, steel plates and cross beam supports, wherein the two ends of each of the cross beams are provided with the steel plates, and each cross beam support is arranged under the corresponding cross beam; the lower end faces of the steel plates are fixedly connected with the top ends of the cross beam supports, and the electric hoist is mounted on the cross beams; the gantry crane provided by the invention is used in tunnel construction.
