Abstract
An elevator support, such as a cable or a belt connected with an elevator car or counterweight, has load-bearing synthetic material strands, which are reinforced by the introduction of a second phase and have a higher modulus of elasticity than that of the unreinforced strands.
Claims15
An elongated load-bearing support with load-bearing strands each having a plurality of fibers, the strands being surrounded by a sheath, the strands comprising:
- a plurality of load-bearing fibers formed of a base material being in a first phase;
- and
- a reinforcing material being in a second phase and being distributed in said base material whereby said reinforcing material increases a modulus of elasticity of the strands in a longitudinal direction of said fibers for supporting at least one of an elevator car and an elevator counterweight.
An elongated load-bearing elevator support device with load-bearing strands each having a plurality of fibers;
- the strands being surrounded by a sheath, the strands comprising:
- a plurality of fibers formed of a base material being in a first phase;
- and
- a reinforcing material being in a second phase and being distributed in said base material whereby said reinforcing material increases a modulus of elasticity of the strands in a longitudinal direction of said fibers for supporting at least one of an elevator car and an elevator counterweight .
A method of producing an elongated elevator load-bearing support device comprising the steps of:
- a. producing a plurality of fibers formed of a base material being in a first phase and reinforced by a reinforcing material being in a second phase and being distributed in said base material;
- b. forming a plurality of load-bearing strands with said fibers;
- and
- c. surrounding said strands with a sheath to form the support device whereby the reinforcing material increases a modulus of elasticity of the strands in a longitudinal direction of the fibers for supporting at least one of an elevator car and an elevator counterweight.
