An exemplary shock-absorbing device for a boarding bridge is for use with lift columns that support the boarding bridge tunnel. The device comprises a first transverse support coupled to the bottom of said lift columns, having an extended length in the transverse direction. A second transverse support is installed separately below the first transverse support. An elastic member is coupled between the first and second transverse supports to elastically support said first transverse supports. Dampers are coupled between the first and second transverse supports to absorb residual vibration from said elastic member. First and second driveshafts are coupled to fixed positions on opposite sides of the second transverse support to be able to rotate. A drive mechanism generates a motive force to move said tunnel and is equipped with a plurality of wheels on opposite sides of said first driveshaft and a plurality of wheels on opposite sides of said second driveshaft.
