PIVOT JOINTS, KITS OF PARTS FOR ASSEMBLING PIVOT JOINTS, MANHOLE BASES, MANHOLES, WATER TRANSPORT SYSTEMS, AND METHODS OF ASSEMBLING WATER TRANSPORT SYSTEMS
A pivot joint (4,4') for elements of a fluid transport system. A first pivot member (5) is connectable to a first element of the fluid transport system and a second pivot member (6) to a second element. Through the pivot joint a liquid-tight liquid flow channel can be established. The first pivot member comprises a larger cage (52) and a smaller cage (50). Each defines a pivot point for a respective rotatable part of the second pivot member mated with the respective cage. Each of the cages has a cage space in which the respective rotatable part is confined. The cage space is delimited by an inner surface. The inner surface forms a running surface (54,56) over which a contact surface (600,620) of the rotatable part is rotationally movable around the pivot point in a direction of rotation from the second element side towards the first element side. The curvature of the running surface in the direction of rotation determines the location of the pivot point. The smaller cage has a smaller running surface (54) and the larger cage has a larger running surface (56). The smaller running surface has a sharper curvature in the direction of rotation than the larger running surface. The larger running surface projects in a tangential direction from the second element side towards the first element side and parallel to the direction of rotation, beyond a second pivot member side edge of the smaller running surface.
