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.
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.
Flat belt CONTI POLYROPE® F25-6x2,0 has a density of 0,18 kg.m-1 and its nominal breaking value is 30 kN.
Benefits of the design
- high tensile strength, constant length
- excellent traction, small pulley diameters
- smooth running without vibrations and noise
- maintenance-free operation
- high resistance to external influences (weather, UV radiation)
- resistance to temperatures from -30 °C to +80 °C (according to use)
