摘要（英）：

The utility model belongs to the technical field of tunnel construction equipment, specifically a large -span self -propelled landing stage. Including the girder, go up the longeron, preceding access bridge I, preceding access bridge II, preceding lift cylinder, support the base, the auxiliary stay, adjusting oil cylinder, the telescope tube, preceding perpendicular hydro -cylinder, before walk the road wheel, back access bridge, back support, the perpendicular hydro -cylinder in back, after walk the road wheel with the back lift cylinder, be fixed with the longeron on the girder, it is equipped with preceding perpendicular hydro -cylinder to go up longeron front end downside, before being equipped with, preceding perpendicular hydro -cylinder lower extreme walks the road wheel, it is equipped with the perpendicular hydro -cylinder in back to go up longeron rear end downside, the perpendicular hydro -cylinder in back is fixed on the girder supporting seat, after being equipped with, girder supporting seat downside walks the road wheel. The utility model discloses possess rail trucks, the rear -guard provides power, and the self -propelled removes, and the access bridge adopts the hydro -cylinder to receive and release, takes curved edge wall template certainly.
