Deformable gangway between two loading platforms carried by successive chassis, notably pertaining to railrods

A deformable gangway interconnecting two carrier platforms of two adjacent chassis with one another, said gangway extending over a connecting articulation between the two adjacent chassis to facilitate carrying a load located between the two interconnected carrier platforms;

• wherein said gangway comprises two lateral connecting elements which are each connected with adjacent end portions of said two adjacent chassis, said two lateral connecting elements support a deformable structure therebetween, when an area of said deformable structure supports a load, said load supporting area becomes fixed, relative to said two lateral connecting elements, while a remaining unloaded area of said deformable structure remains movable, relative to said two lateral connecting elements, to compensate for contraction and expansion resulting from relative movement between said two adjacent end portions of said two carrier platforms during travel;
• and
• said deformable structure comprises a plurality of parallel transversely arranged slats, and elastic members support opposed extremities of said slats on said two lateral connecting elements, and said elastic members each include a shim with a frusto-conical skirt and an end shoulder, and said shim is mounted so as to provide a wedging action to separate adjacent slats from one another.

A deformable gangway interconnecting two carrier platforms of two adjacent chassis with one another, said gangway extending over a connecting articulation between the two adjacent chassis to facilitate carrying a load located between the two carrier platforms,

• wherein said gangway comprises a plurality of parallel transversely arranged slats which are supported by a pair of longitudinally arranged spaced apart parallel supporting and guide arms extending between end portions of the two carrier platforms;
• said plurality of parallel transversely arranged slats are each moveable along said pair of spaced apart supporting and guide arms to compensate for relative movement between said adjacent end portions of the two carrier platforms during travel of said adjacent chassis;
• and, when a load rests on one or more of said slats, each said slat supporting the load become fixed, relative to said pair of spaced apart supporting and guide arms, while a remainder of said slats, which are unloaded, remain moveable to compensate for the relative movement between adjacent end portions of the two carrier platforms during travel.
