Abstract: Bridge crane with articulated rotary boom, which includes a beam (13) that supports a boom (17) able to rotate in a substantially horizontal plane about a substantially vertical pivot (14), which is located substantially at the center of the span of the beam (13) and is fixed below the beam (13), the boom (17) consisting of at least two elements (18-118-218) which can be positioned vertically in relation to each other by means of cylinder/piston actuators (121-221), the boom (17) being anchored by means of its first element (18) to a rotary platform (24) positioned below the beam (13), an operator's cage (15) and a motor unit (16) located below the beam (13) being comprised in cooperation with the central pivot (14) of rotation, the motor unit (16) being offset laterally in contraposition to the boom (17) so as to act as a counterweight, the first element (18) of the boom (17) being able to oscillate and to be positioned vertically by means of a first cylinder/piston actuator (21).

Abstract: Rehabilitation machine (10) for railway road beds, which comprises a framework (11) rested on a front bogie (12) and rear bogie (13), cabs (14-15) to drive the machine during its travels, an excavation chain (20) cooperating with a hopper (21) in the transfer of excavated material onto an elevator (22), and a leading end (24) and trailing end (124) relative to the direction of advance (19) of the machine (10), and also comprises at one end a first front conveyor (27) to deliver a mixture of aggregate materials (26) and a second front conveyor (33) to deliver metalling (32) towards the machine (10) and also discharge conveyors (23) to discharge excavated material from the machine (10).

Abstract: System to feed and discharge materials continuously for the rehabilitation f railway road beds and the like in cooperation with operational machines (21) coupled to a plurality of waggons (10) storing such materials, in which system each storage waggon (10) comprises:hopper (11) to contain materials, with lower movable shutters (12) to open and close the hoppers (11),a lower conveyor (13) cooperating with the hoppers (11) and extending substantially along the whole length of the waggon (10) in a horizontal plane,a upper conveyor (14) extending substantially along the whole length of the waggon (10) in a horizontal plane, andan almost vertical conveyor (16) cooperating with the lower conveyor (13) in the transfer of materials.

Abstract: Continuous ballast-tamping machine having a machine structure able to run with a straight, uniform motion along a railroad line and having a tamping structure connected thereto able to move lengthwise along the machine structure with a straight, alternating movement owing to the action of an actuation means. The tamping structure is adapted to consolidate ballast in correspondence with sleepers that bear the railway line. The tamping structure has a plurality of tamping heads each of which has a tine holder, and each tine holder is positionable vertically in an independent manner in relation to the railway line. Independent means are included for providing vibratory motion for each pair of tamping heads.

Abstract: System for the continuous reciprocal self-alignment of rails on sleepers, which comprises pre-installed bolts or like locking means in cooperation with a machine which lays, positions and secures the elements that clamp the rails, the rails being first anchored and positioned relative to each other and then positioned relative to the sleepers.

Abstract: A railway ballast renewal machine for renewing a railway road bed within a tunnel is disclosed. The device has a scarifier to loosing the metalling, a work unit to grip and retain the alignment of the rails as well as remove the metalling from between the sleepers, a riddle to sort the metalling, and a device to spread the sorted metalling back on the railway bed. The metalling is removed from between the sleepers by a movable case which moves vertically between the sleepers.
