TRAVELLING CABLE OF AN ELEVATOR, AND AN ELEVATOR

摘要

A travelling cable of an elevator, more particularly of a passenger transport elevator and/or freight transport elevator, includes a protective envelope, conductors for transmitting electrical energy and data between the elevator car and the elevator hoistway, and one or more load-bearing bearer parts of essentially the length of the travelling cable for fixing the travelling cable at its first end to the elevator car and at its second end to the elevator hoistway, and which bearer part includes glass-fiber reinforcements and/or aramid-fiber reinforcements and/or carbon-fiber reinforcements and/or polybenzoxazole-fiber reinforcements and/or polyethylene-fiber reinforcements and/or nylon-fiber reinforcements in a polymer matrix material. An elevator includes the travelling cable.
