Abstract
A slip-form paver is provided in the form of a tractor (2) including a machine frame (4) having substantially parallel longitudinal beams (8) at opposite ends of which are track assemblies (14). The machine frame (4) includes a base frame (20) and telescopic cross beams (18) located between the base frame (20) and the longitudinal beams (8). An intermediate frame (24) is located beneath the base frame (20) and is selectively vertically adjustable. Two working mechanisms (28, 32) are in transverse relationship to the longitudinal beams (8), and the latter are transversely shiftable to selectively lengthen or shorten the overall transverse working width of the paver.

A slip-form paver comprising a tractor (2) including a machine frame (4) having substantially parallel longitudinal beams (8), track assemblies (14) at opposite ends of said longitudinal beams (8), said machine frame (4) including a base frame (20), telescopic cross beams (18) located between said base frame (20) and said longitudinal beams (8) for selectively varying the working width of the paver, an intermediate frame (24) located beneath said base frame (20), means (36) for adjusting the vertical distance of said intermediate frame (24) relative to said base frame (20), two working means (28, 32) disposed in transverse relationship to said longitudinal beams (8), means (22, 25) for supporting said two working means (28, 32) relative to said intermediate frame (24), means for supporting said two working means relative to said longitudinal beams (8), and said supporting means (22, 25) for supporting said two working means (28, 32) relative to said intermediate frame (24) being constructed and arranged for effecting movement of said two working means (28, 32) relative to said intermediate frame (24) to selectively lengthen or shorten the overall transverse length of said two working means (22, 25) and thereby accommodate to a desired working width of the paver.
A slip-form paver comprising a tractor (2) including a machine frame (4) having substantially parallel longitudinal beams (8), track assemblies (14) at opposite ends of said longitudinal beams (8), said machine frame (14) including a base frame (20), telescopic cross beams (18) located between said longitudinal beams (8) for adjusting the transverse working width of the paver, at least one transverse rail guide (56;
- 142) mounted transversely between said longitudinal beams (8), said at least one transverse rail guide (56;
- 142) including at least two relatively movable rails (60, 62;
- 144, 146), a carriage (70;
- 128) movably mounted for displacement along said rail guides (56;
- 142);
- a rope drum (78, 136) and an associated rope drum drive (140) located at one of each longitudinal beam (8) and track assembly (14), and a rope (74) connected to said carriage (70;
- 128) and wound upon each rope drum (76, 136) for effecting transverse displacement of said carriage (70;
- 128).
A slip-form paver comprising a tractor (2) including a machine frame (4) having substantially parallel longitudinal beams (8), track assemblies (14) at opposite ends of said longitudinal beams (8), said machine frame including a base frame (20), telescopic cross-beams (18) located between said longitudinal beams (8) for adjusting the transverse working width of the paver, said machine frame (4) carrying working means (28, 32) disposed in transverse adjustable relationship to said longitudinal beams (8), said base frame (20) carrying a transverse smoothing beam (150), said transfer smoothing beam (150) including two beam segments (154, 158), and means (156) for pivotally connecting each of said beam segments (154, 158) at substantially the middle of the working width of the paver to form an adjustable roof profile.
