Claim:
Modular plastic belt modules for a skid buffer system, each of the modular plastic belt modules having a width, and a length, where the width and the length define a plane, and having a thickness orthogonal to said plane, such that each module is limited by two longitudinal sides and a front and rear side, where each module along the front and rear sides is provided with plural eye parts, spaced by openings, such that an eye part on one edge fits inside an opening between two eye parts on an adjacent module, wherein said eye parts have apertures parallel to the front and rear sides-configured to accommodate hinge pins, wherein adjacent modules are connected by fitting eye parts on one module inside openings between two eye parts on an adjacent module and connecting the adjacent modules by inserting hinge pins laterally through overlapping apertures and wherein spaced in parallel lines of the modules connected by the hinge pins and wherein spaced modules in the lines of connected modules have upstanding flanges connected to and parallel to the two longitudinal sides, where each flange has an axle accommodation surface in the shape of either a U-shaped cradle or an aperture, and an axle in said axle accommodation surfaces said axle being arranged parallel to the front and rear sides in said accommodation surface and where said axle between the upstanding flanges is provided with a first larger inner roller, and where smaller outer rollers are provided in either end of the axle, outside the sides of the flanges, wherein the upstanding flanges are one or two separate flange elements, where each flange element is mechanically fastened to the modular belt module, and where each flange element comprises the accommodation surface for accommodating the axle.
