Abstract: Cart for building a bridge board forward progressive which incorporates a system for positioning reinforcement pieces, which have displacement tracks on the upper working surface and runners on which the reinforcement pieces are situated and which are displaced on the displacement tracks, where by means of the system for positioning reinforcement pieces it situates the reinforcement pieces in a position of the upper working surface for a subsequent concreting of a section of the board of the bridge, with the cart being fixed in the position thereof.

Abstract: The invention relates to a traveller (1) for the construction of engineering works, comprising two structures, namely: a securing structure (2) for securing to the already built engineering work, and a working structure (3) on which construction of the work advances. The traveller is characterized 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 built 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).

Abstract: Movable centring for platforms in ports which comprises a mobile structure (1) with various formworks (2) and is supported on piles (3). The support of the mobile structure (1) on the piles (3) is carried out by means of, at least, two supporting devices (5), wherein each supporting device (5) comprises one front supporting beam (6d), which comprises at least two coupling pieces (18), one rear supporting beam (6t) which comprises at least two coupling pieces (18) and a lattice (7), beneath each supporting beam (6d, 6t). The two supporting beams (6d, 6t) are joined together by means of the at least two coupling pieces (18), thus leaving the supporting device (5) fixed to the pile (3) by means of this union, and joining each supporting beam (6d, 6t) to the mobile structure (1) by means of, at least, two vertical latching bars (8).
