Patent attributes
A compactly constructed guide system has a run surface for guiding the run of the chain rollers. To guide the sides of the steps, a sliding pin arranged on a step rests on a side surface. A counter-surface serves as a counter-guide for the chain rollers and prevents the chain links from being pushed together. By means of an encapsulation, the step rollers, the chain links, and the running surface can be protected from dirt, dust, water, objects, etc. For run guidance of the step roller, a running surface is provided. An oil collecting channel prevents dripping of lubricating oil. The guide system rests on a bracket plate projection and is releasably connected to the bracket plate. The single-piece guide system is simple and efficient to install and can be accurately positioned at the sides against stops.
