Abstract (en)
Suspension means having a width B and a thickness D for a traction sheave elevator in the form of a flat belt with a plurality of traction means strands which are embedded in a friction-increasing belt base material via which they contact the traction sheave and optionally at least one further deflection pulley during regular operation, characterized in that directly adjacent traction means strands are spaced apart from one another by a smaller distance in the region of the belt center (at B/2) than in the regions of the flat belt near the flanks.
