Claims

[Scope of utility model registration request]

In a bridge type crane that is composed of a main structure such as a superstructure consisting of two sets of front and rear legs, a boom, a girder, an upper strut, and a tension member, and is equipped with a trolley that can run on the boom and the girder, the superstructure is supported by the leg via the girder portion so as to be swingable in the horizontal direction, and a shock absorber is inserted between the girder and the leg so as to restrain the swinging in the horizontal direction. Bridge type crane with vibration damping device.
