Definitions

• the elevator car and the counterweight are most commonly- moved in elevators via hoisting roping moved by a traction sheave.
• a traction sheave can be used to brake the movement speed of an elevator car in a situation in which the elevator car is moving downwards by directing a force pulling upwards from the traction sheave to the elevator car with the hoisting rope between the traction sheave and the elevator car.
• a counterweight moving upwards in this type of situation cannot be braked with the hoisting rope between the traction sheave and the counterweight, because a force pushing the counterweight downwards cannot be transmitted along the rope.
• An elevator is achieved, the tolerance to high temperatures of which is better than before.
• An elevator is achieved, the rope of which possesses high thermal conductivity combined with good tolerance to high temperatures .
• An elevator is achieved, wherein the deceleration of the car and/or counterweight can be increased with a brake during traction sheave braking.
• An elevator is achieved, wherein it is easy to prevent movement of the car of which from a landing with the doors open with a brake.
• the individual reinforcing fibers are homogeneously distributed in the aforementioned matrix.
• the aforementioned reinforcing fiber over 50% of the surface area of the cross-section of the load-bearing part is the aforementioned reinforcing fiber, preferably such that 50%- 80% is the aforementioned reinforcing fiber, most preferably such that 55%-70% is the aforementioned reinforcing fiber, most preferably such that approx. 60% of the surface area is reinforcing fiber and approx. 40% is matrix material.
• the reinforcing fibers together with the matrix form a uniform load-bearing part, inside which relative abrasive movement among the fibers or between the fibers and the matrix does not essentially occur.
• the load-bearing part is composed of the aforementioned polymer matrix, reinforcing fibers bound to each other by the polymer matrix, and also possibly a coating around the fibers, and possibly also additives mixed into the polymer matrix.
• the arrangement presented wherein the elevator car and/or the counterweight each comprise a brake, can be used if necessary also as a safety brake in the following situations : in connection with unintended movement when the car runs away from the door zone with the doors open, and/or as a terminal slowdown device in the terminal control zone of the hoistway to enhance deceleration during braking in situations in which the approach of a terminal floor according to the speed reference is malfunctioning due to a defect, and/or as a booster to emergency braking in those elevators in which the dimensioning rule of the "emergency stop" load case according to Annex M of EN81-1 is not fulfilled, which is typical in elevators in which emergency braking is more critical than normal drive in respect of traction sheave friction.
• the reinforcing fibers being in the polymer matrix in the load-bearing part means here that in the invention the individual reinforcing fibers are bound to each other with a polymer matrix e.g. in the manufacturing phase by embedding them in the material of the polymer matrix.
• the interspaces of individual fibers bound to each other with the polymer matrix comprise the polymer of the matrix.
• a large amount of reinforcing fibers bound to each other in the longitudinal direction of the rope are distributed in the polymer matrix.
• the reinforcing fibers are preferably distributed essentially evenly, i.e.
• the individual reinforcing fibers of the load- bearing part are mainly surrounded with polymer matrix, but fiber-fiber contacts can occur in places because controlling the position of the fibers in relation to each other in the simultaneous impregnation with polymer matrix is difficult, and on the other hand fully perfect elimination of random fiber-fiber contacts is not wholly necessary from the viewpoint of the functioning of the invention. If, however, it is desired to reduce their random occurrence, the individual reinforcing fibers can be pre-coated such that a polymer coating is around them already before the binding of individual reinforcing fibers to each other.
