PU Coated Flat Ropes POLYROPE

The CONTI POLYROPE® PU Coated Flat Ropes are certified for use as a suspension device for installation in passenger or freight elevators according to the EN 81-20/50 Standard and the Lift Directive 2014/33/EC

Description and Use

The CONTI POLYROPE® PU Coated Flat Ropes consist of steel cables that are embedded in a coat made of high wear resistant polyurethane. They serve as a suspension device of elevator cabins in passenger and freight elevators.

Significantly smaller pulleys make it possible to use smaller gear motors and create space-saving drives with low inertial masses. This reduces production costs and energy consumption.

Construction

The CONTI POLYROPE® consists of 2.0 mm thick steel ropes, which are embedded in a black polyurethane coating. The test results have shown that  its service life is three times longer than the service life of current steel ropes under the same conditions. Long-term strength shows only a slight decrease after several millions of cycles. The traction test for the cycle value confirms the high wear resistance of the entire system.

POLYROPE výtahový pás - vytvoření

The horizontal alignment of the steel cords gives the belt its flat shape. Each PU belt contains more steel wires than a conventional steel cable.

Material and Construction Innovations

Thanks to its greater flexibility and traction the CONTI POLYROPE® enables compact drives with much smaller pulley diameters in comparison to conventional drives with steel cords.

The CONTI POLYROPE® flat belts are used in combination with corresponding traction and deflection pulleys and wedge sockets.
