PROBLEM TO BE SOLVED: To provide a bridge installing device for shortening a construction period, by facilitating resuspension of a segment. SOLUTION: This bridge installing device has an installing work vehicle capable of self-traveling on an existing beam, and a transfer carriage capable of self-traveling on the existing beam. The installing work vehicle has a hoisting mechanism, and a working platform. The transfer carriage has a hoisting mechanism for the transfer carriage. The transfer carriage can shorten the construction period by facilitating the resuspension of the segment to the installing work vehicle from the transfer carriage, due to being movable up to a position of the installing work vehicle on rails laid on both sides of the installing work vehicle.
