The invention relates to a traveller (1) for the construction of engineering works, comprising two structures, namely: a structure (2) for securing to the already formed engineering work, and a working structure (3) on which construction of the work advances. The traveller is characterised in that the securing structure (2) comprises: a first end ring (6) and a second middle ring (7), both of said rings (6, 7) being coupled to the periphery of the section (27) of the already formed work; at least one transom bar (9) that joins the end ring (6) and the middle ring (7) on the side of the carriage (1); and connecting elements between the end ring (6) and the middle ring (7). The working structure (3) comprises exterior formwork (25) and floor formwork (23), in which the securing structure (2) and the working structure (3) are joined at the lower part thereof by a main load-bearing girder (10, 10') and at the upper part thereof by the forward tracks (18, 18'). |
