Claims
- 1. A fall arrest system comprising: a horizontal lifeline; a connector slideably supported on the horizontal lifeline; and at least one intermediate support for the horizontal lifeline, each of the at least one intermediate supports comprising:an anchor body having a substantially u-shaped bracket; a pair of rotatable star wheels having a plurality of projections, the projections from one star wheel meshing with the projections from the other star wheel within the bracket to support the horizontal lifeline while permitting the connector to pass there-through; and each star wheel being mounted on the bracket at an angle to each other such that the projections of each star wheel, when supporting the horizontal lifeline, may in turn be supported by the bracket if the projections are deformed by a load being applied to the horizontal lifeline.
- 2. The fall arrest system of claim 1 wherein the connector comprises a pulley for rolling support on the horizontal lifeline.
- 3. The fall arrest system of claim 2 wherein the connector further comprises a plurality of wheels for rolling support on a plurality of rails mounted on the anchor body above the projections of the star wheels.
- 4. The fall arrest system of claim 1 wherein each star wheel has at least six projections.
- 5. An intermediate support for a horizontal lifeline comprising:an anchor body having a substantially u-shaped bracket; a pair of rotatable star wheels having a plurality of projections, the projections from one star wheel meshing with the projections from the other star wheel within the bracket to support the horizontal lifeline; and each star wheel being mounted on the bracket at an angle to each other such that the projections of each star wheel, when supporting the horizontal lifeline, may in turn be supported by the bracket if the projections are deformed by a load being applied to the horizontal lifeline.
- 6. The fall arrest system of claim 5 wherein each star wheel has at least six projections.
