Flat belt for flat belt drive of lift, has traction supports arranged at distance from each other, where traction surfaces of traces are combined to form surface that is smaller than traction surface formed by entire width of belt surface

摘要

The belt has traction supports (5) arranged at a distance from each other in a common plane and running in longitudinal direction of the belt, where the belt is embedded in elastomer material i.e. polyurethane. A groove (2) runs in longitudinal direction of the belt, and is formed in a projection of the traction supports on a belt surface (3a). The belt is structured in single traces (7) by the groove, where single trace traction surfaces (8) of the traces are combined to form a surface that is smaller around 5-10 percentage than a traction surface formed by entire width of the belt surface.
