Abstract
In an elevator rope, an inner layer rope includes a fiber core that includes a. bundle of fibers; a plurality of inner layer rope strands that each include a plurality of steel wires are disposed around an outer circumference of the fiber core; and a resin inner layer rope coating body that is coated around an outer circumference of the fiber core and a layer of the inner layer rope strands. A plurality of outer layer strands each including a plurality of steel wires are disposed around an outer circumference of the inner layer rope coating body.
Claims16
An elevator rope comprising:
- an inner layer rope comprising:
- a fiber core that includes a bundle of fibers;
- a resin fiber core coating body on an outer circumference of the fiber core;
- a plurality of inner layer rope strands that each include a plurality of steel wires, and that are disposed around an outer circumference of the resin fiber core coating body;
- a resin inner layer rope coating body that is coated around an outer circumference of the resin fiber core coating body and a layer of the inner layer rope strands;
- and
- a plurality of outer layer strands that each include a plurality of steel wires, and that are disposed around an outer circumference of the inner layer rope coating body,
- wherein the inner layer rope strands are greater in number than the outer layer strands.
An elevator rope comprising:
- an inner layer rope comprising:
- a fiber core that includes a bundle of fibers;
- a resin fiber core coating body on an outer circumference of the fiber core;
- a plurality of inner layer rope strands that each include a plurality of steel wires, and that are disposed around an outer circumference of the resin fiber core coating body;
