A bridge and method of installing the bridge for spanning a hydrological surface feature. The bridge includes a deck spanning the hydrological surface feature, at least one tower, and a tensile support system connecting the deck with the tower under tension to provide a tensile force for supporting the deck. A density and surface area of the deck, and the tensile force provided by the tensile support system, are selected to facilitate flotation of the deck on the hydrological feature with a top surface of the deck at a selected elevation above a surface the hydrological surface feature while supporting a selected load and while the deck is supported by the tensile force.

A corrugated plate structure includes a plurality of corrugated plates connected together to form a corrugated structure having a corrugation direction and a cross-corrugation direction. A reinforcement system includes: a first bracket and a second bracket, where the first bracket extends substantially parallel to the cross-corrugation direction and mounted to side-by-side first and second corrugation crests so as to pass over a corrugation valley that joins the first and second corrugation crest, and where the second bracket is spaced in the corrugation direction from the first bracket, and the second bracket extends substantially parallel to the cross-corrugation direction and mounted to the first and second corrugation crests so as to pass over the corrugation valley. An elongated reinforcing member extends substantially parallel to the corrugation direction and mounted to both the first bracket and the second bracket.

Device at inclined floors in passenger bridges for connection between a terminal building and a ship or an aircraft, includes two or more consecutive walking tunnels adjustable to be inclined in relation to the horizontal plane, and which include horizontal resting planes, wherein the floor of the walking tunnel extends out from a floor portion constituting the resting plane in opposite directions from the resting plane. A first short end of the respective floor of the walking tunnel is pivotally fixed to the floor portion, constituting the resting plane, the other short end of the respective floor rests on a sliding or rolling surface arranged so that the floor can move lengthwise relative to the sliding or rolling surface. The floor portion forming the resting plane is arranged to be pivoted about a horizontal axis via an electric actuator or hydraulic cylinder, whereby the resting planes assume a horizontal position.

A dock leveler includes a frame configured to support the dock leveler that includes at least one leg. The at least one support leg having a first tube operatively coupled to the frame. A second tube is slidably disposed within the first tube such that the second tube is operable between a first position and a second position. The second tube includes a locking portion. A foot is positioned on an end of the second tube and a shipping pin is configured to engage the locking portion of the second tube such that the second tube is selectively held in one of the first or second positions.

A gangway comprises a fixed platform and a support structure. The support structure is connected to the fixed platform in a manner that allows the support structure to rotate with respect to the fixed platform. A releasable position locking assembly inhibits rotation of the support structure in a raising direction.

An airport is provided which is compact and which is such as to facilitate efficient movements of aircraft into and out of parked positions and to also facilitate movements of passengers. Aircraft can be moved in a forward direction both when entering and when exiting each parked position. Loading/unloading means include escalators that move passengers between underground gate areas and landings at about ground level and also include ramp structures that can move passengers between the landings and openings in the fuselage of a parked aircraft. Structures illuminate gate areas and landings of the loading/unloading means and extend above ground level but such structures and the ramp structures are so designed that neither interferes with movements of aircraft into and out of parked positions. The parked positions can be located in rows with aisles between such rows for movement of aircraft. The gate areas underlie and correspond to the parked positions and are thereby located in rows with aisles between rows for movements of passengers to and from and between gate areas. Passengers can thereby move through minimal distances either when departing or when arriving and either exiting the airport or moving between gate areas to depart on another aircraft.
