Abstract:
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.
