Fixing-kit with wedge for Conti Polyrope®
Flat belt CONTI POLYROPE® must be applied together with a normalized fixing-kit.
The end connections of the Polyrope shall be self tightening wedge type sockets , they shall be made of metallic material and shall resist 80% of the minimum breaking load of the Polyrope, the angle of the housing and wedge shall be equal and in between 20° and 25°. Other types of end connectors are allowed only after a written declaration is received that will function as an extension to this certificate.

Traction and deflection pulleys
Flat belt CONTI POLYROPE® shall be applied in combination with a dedicated traction pulley with semicircular grooves. For POLYROPE with flat backside, deflection pulleys may have either the same grooves as the traction sheave in case of twisted application, or a convex shape (crowned) for alingment and a rim to protect against extreme sideward movementrs, in case the flat side is used as running surface.
