Abstract
An energy guiding chain for guiding hoses, cables and the like has a number of chain links connected to one another in articulated fashion which are formed by parallel straps connected by cross-members. The energy guiding chain can be moved in such a way that it forms an upper strand, a lower strand and a deflection zone connecting the two, where the upper strand rests on the lower strand. In order that the upper strand can be moved lying on the lower strand with the least possible power and low wear, and the chain is of the simplest possible design, at least some of the chain links of the upper strand and/or the lower strand are provided with rollers that can roll on running surfaces provided on the chain links of the opposite strand when the energy guiding chain travels.
