  • a horizontal moving means 5 attached to said girder 1 and a fixed plate 4 on the dock.
  • the horizontal moving means 5 is a double acting hydraulic cylinder.
  • a position correcting means 6 engages the vertical surfaces b which extend upwardly from the opposed side edges of inclined guide face a and the girder 1 in such a way as to adjustably move the girder 1 laterally in a horizontal the said supporting girder 7 which extends beneath and supports main bridge gangway l, and guide rollers 11 are provided on both sides, at the eente'r,'f'ront and rear of girder 7.
  • a shackle 12 is provided between the elevating means 8 or 9 and the support girder 7 to give flexibility thereto and to avoid maladjustment by lateral load.
  • the horizontal moving means 5, for shifting the said gangway to and fro, is equipped with two hydraulic oil cylinders 13, 14 at each side of the base of the gangway 1, cylinders 13 being fixed to the gangway l as shown in FIGS. 1, 2, and 7 and having a telescopic rod in the direction of the receiving plate 4 and another telescopic rod 13b in the direction of shiftable receiving means 15.
  • Another cylinder 14 is screwed at one end thereof to said shiftable receiving means 15, and to a step or shoulder 16 formed on both side walls b of inclined guide face a, at the other end thereof.
  • the shiftable receiving means 15 is guided by rollers 18 along 9 guide means 17 formed on the wall b in :such a way as to shift means 15 with respect to said shoulder 16.
  • the guide means 17 takes the form of a pair of upwardly directed horizontal shoulders formed in the surfaces b and extending rearwardly from' the vertical shoulders 16 which are formed in the surfaces b, respectively.
  • the rollers 18 roll along the horizontal shoulders 17 which form a guide means for the receiving means 15.
  • the receiving means 15 is moved to and fro by the actuating cylinders 13 and 14.
  • Four position correction means 6 are attached to the gangway 1 on both sides thereof in the front and the rear as shown in FIGS. 1 and 2, the detailed construction of which are as indicated in FIG. 6.
  • mobile body 19 having a rotatable ball roller 20 is supported by the lower side of the gangway 1 and constructed in such a way as to move toward and away from the surface b by the action of hydraulic cylinder 21.
  • guide roller 20 is placed to the surface b of the quay by actuating said cylinder 21. to correct the position of the girder in the lateral direction.
  • the hydraulic pressure moving device 5 slides the gangway 1 toward the direction of the ferry.
  • the moving device 5 is actuated by bringing the end of the rod 13a of one of the cylinders 13 to contact the receiving plate 4 and brings the apparatus into the position shown in FIG. 7 and the girder 1 slides toward the ferry.
  • the foot board 24 is placed at the rear of the gangway 1 as in FIG. 16 and the support girder 7 is lowered by the elevating means 3 to support and fix the outboard end of the gangway l on the ferry boat as is shown in FIGS. 4 and 17, and the elevating means 3 is further lowered to completely disconnect the support gangway 7 from the gangway l.
  • the cylinder 13 is operated to disengage the drawing device from the receiving plate 4, and slide the shiftable receiving means 15 toward the end of the cylinder 14 to disconnect the gangway from the quay.
  • the gangway 1 will be supported by the inclined guide face a only by the rotatable roller 2 and follows the movement of the ferry boat horizontally or vertically smoothly.
  • the four position correcting means 6 will act as guide rollers by contacting the rotatable ball roller at the tip of the mobil body 19 with surface b when the gangway 1 slides so that when the gangway 1 reaches a predetermined position, the cylinder 21 is actuated to disengage the roller 20 from the quay.
  • the above operation is conducted when the gangway 1 moves toward the ferry and is supported.
  • the gangway 1 is raised as shown in FIG. 16, and the horizontal moving means 5 is used to create a situation as shown in FIGS. 1, 2, and 15.
