A belt of an elevator system includes one or more tension elements extending longitudinally along a length of the belt, and an elastomeric jacket at least partially enveloping the one or more tension elements. The jacket defines a traction side configured to be interactive with a traction sheave of the elevator system and a back side opposite the traction side. A protective tape is applied to the elastomeric jacket at the back side. A method of assembling an elevator system includes forming a belt, and installing the belt in a hoistway of the elevator system. One or more additional components of the elevator system are installed in the hoistway. A protective tape is removed from a jacket of the belt after installation of the one or more additional components is completed.

A composite elevator belt for engaging a sheave includes a load carrier having at least one load carrier strand extending substantially parallel to a longitudinal axis of the load carrier and a resin coating surrounding the at least one load carrier strand and defining a plurality of predetermined, deformable cavities within the resin coating adjacent the at least one strand. When the elevator belt is bent around the sheave, the elevator belt defines a neutral bending zone located within the elevator belt generally coincident with the longitudinal axis, a tension zone radially outward of neutral bending zone, and a compression zone radially inward from the neutral bending zone.

An elevator tension member is presented that has one or more steel cords as strength members that are encased in a jacket of thermoplastic polyurethane elastomer. The thermoplastic polyurethane elastomer is selected on the basis of its thermal properties in that the glass transition temperature of the hard phase (Tg HS) is above 90° C. In preferential embodiments that thermoplastic polyurethane elastomer has a crystallisation temperature (Tg) that is at least 20° C. higher than Tg HS. In other preferential embodiments the sum of Tg HS and Tc is higher than 200° C. Such thermoplastic polyurethane elastomers exhibit an unexpected increase in useful lifetime when compared to conventionally used polyurethanes. Moreover the invention provides a simple method to select an appropriate thermoplastic polyurethane elastomer.
