## Abstract

A safety cable system for installation during building construction is provided and includes a first track mounted to a first structural element of a building, a first plurality of anchors slidably engageable with the first track, a second track mounted to a second structural element of a building, a second plurality of anchors slidably engageable with the second track, and a plurality of cables interconnecting the first plurality of anchors and the second plurality of anchors. The first plurality of anchors, the second plurality of anchors, and the plurality of cables are positionable vertically at a plurality of different heights above a floor of the building, or horizontally at a plurality of different positions above the floor. Also provided are stops for restricting movement of the first and second plurality of anchors, roller bearings that capture the plurality of anchors in the tracks and allow the anchors to slide with respect to the tracks, plates and associated mounting hardware for mounting the tracks, turnbuckles for tensioning the cables, and tie points for tying a netting between the tie points.

## Claims

### Claim 1

A safety cable system, comprising:
a transportable frame comprising a plurality of vertical members and a plurality of horizontal members interconnecting the plurality of vertical members, the transportable frame positionable to surround a support column of a building; and
a plurality of movable cable assemblies attached to the transportable frame, each of the plurality of movable cable assemblies movable with respect to the frame,
wherein the plurality of vertical members of the transportable frame are positioned at corners of the transportable frame and extend upwardly from a floor or slab on which the transportable frame rests, at least two of the plurality of vertical members include wheels attached at bottom ends of the vertical members to transport the transportable frame, and at least another two of the vertical members include anchors attached at bottom ends of the vertical members to mount the frame to the floor or slab, and
wherein each of the plurality of movable cable assemblies is movable along a track mounted horizontally between a pair of the plurality of vertical members.

### Claim 2 (depends on 1)

The safety cable system of claim 1, wherein each of the plurality of movable cable assemblies comprises a plate movable within the track.

### Claim 3 (depends on 2)

The safety cable system of claim 2, wherein the plate includes a wheel or roller to facilitate sliding of the plate with respect to the track.

### Claim 4 (depends on 2)

The safety cable system of claim 2, wherein each of the plurality of movable cable assemblies comprises a turnbuckle for selectively tensioning a respective one of the plurality of movable cable assemblies, the turnbuckle attached at one end to the respective one of the plurality of movable cable assemblies and at an opposite end to a respective one of the plurality of movable plates.
