Elevators use different types of industrial belts in different sections. One of these belts that connects to all floors is the elevator belt. This belt is actually connected with a small motor and is responsible for opening the sliding elevator doors. Endless or closed loop elevator belts تسمه آسانسور are used in different lengths and widths according to the motor connection. The elevator belt has ribs that are often perpendicular to the main line of the belt and is produced from powerful polymer compounds, including PU polyurethane. The elevator belt is often used as a grooved V-belt.
The elevator belt often has metal or fiberglass cords between the polymer layers to increase the tensile strength against length change. On the outer surface of the internal ribs of the elevator belt تسمه انتقال نیرو, the strong polyamide PA polymer is often used to increase the wear resistance. The type of ribs on the inner surface of the elevator belt is often trapezoidal, which creates a stronger connection, but these ribs have a very high stress concentration at the foot of the lateral sides of the trapezoid. In some types of designs, curved or curvilinear ribs are also used.
