Abstract
A handrail has an outer shell at least partially coated with at least one layer of a metal and/or at least one metal compound, and is formed of a plurality of interconnected grip elements located on a power transmission chain or belt. Ends of adjacent grip elements can be pushed inside each other, allowing the grip elements to tilt with respect to each other, particularly in bent or curved sections, without deforming the elements. Each grip element may have an interior chamber or recess which overlaps an external chamfer or recess of an adjacent grip element. The outer shell may be double walled with inner and outer walls
