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.

Abstract: The brake force occurring at the brake shoes are distributed such that part of the brake force is transmitted via the brake shoe holding arrangement to the brake support member and the other part of the force is transmitted through the floating caliper to the brake support member. For this purpose, the surface of the brake shoes close to the floating caliper is provided with a friction lining so that the coefficient of friction between the floating caliper and the brake shoes is 0.5 times smaller than the coefficient of friction between the brake shoe pads and the brake disc.
