Abstract

A fall arrest system for use with a platform includes a harness configured to be worn by an operator, a first bracket and a second bracket configured to be coupled to the platform, a horizontal support including a first end portion coupled to the first bracket and a second end portion coupled to the second bracket, and a harness adapter coupled to the harness, the harness adapter defining an aperture that receives the horizontal support. The harness adapter is repositionable along a length of the horizontal support.

First claim

What is claimed is:

1. A fall arrest system for use with a platform, comprising:
a harness configured to be worn by an operator;
a first bracket and a second bracket configured to be coupled to the platform, wherein the first bracket defines a recess configured to receive a guardrail of the platform when the first bracket is coupled to the platform, and wherein the second bracket includes a boss;
a horizontal support including a first end portion coupled to the first bracket and a second end portion coupled to the second bracket, wherein the second end portion forms a slot configured to receive the boss; and
a harness adapter coupled to the harness, the harness adapter defining an aperture that receives the horizontal support,
wherein the harness adapter is repositionable along a length of the horizontal support.

2. The fall arrest system of claim 1 , wherein the first bracket and the second bracket are removably coupled to the platform.

3. The fall arrest system of claim 2 , wherein the horizontal support is removably coupled to the first bracket and the second bracket.

4. The fall arrest system of claim 1 , wherein the boss is a first boss, wherein the first bracket includes a second boss defining a boss aperture, and wherein the first end portion of the horizontal support extends through the boss aperture.

5. The fall arrest system of claim 4 , wherein the first end portion of the horizontal support includes a threaded stud, further comprising a fastener in threaded engagement with the threaded stud, and wherein the fastener engages the second boss to apply tension to the horizontal support.

6. The fall arrest system of claim 1 , wherein the boss defines a boss aperture and the second end portion of the horizontal support defines a first support aperture and a second support aperture, wherein the first support aperture and the second support aperture are configured to align with the boss aperture when the slot receives the boss.

7. The fall arrest system of claim 6 , wherein the horizontal support includes a cable extending between the first end portion and the second end portion.

8. The fall arrest system of claim 4 , wherein the second boss extends above the recess such that the horizontal support is positioned above the guardrail when the first bracket is coupled to the platform.

9. The fall arrest system of claim 1 , wherein the recess is configured to receive a first member of the guardrail of the platform when the first bracket is coupled to the platform.

10. The fall arrest system of claim 9 , wherein the recess is a first recess, wherein the first bracket further defines a second recess configured to receive a second member of the guardrail when the first bracket is coupled to the platform, and wherein the first recess is angularly offset from the second recess.

11. The fall arrest system of claim 10 , wherein the first recess and the second recess are substantially perpendicular to one another.

12. The fall arrest system of claim 10 , wherein the second bracket further defines a third recess configured to receive the guardrail when the second bracket is coupled to the platform.

13. A platform assembly, comprising:
a platform defining a support surface for an operator, the platform including a guardrail fixedly coupled to the support surface;
a first bracket removably coupled to the guardrail and defining a lateral aperture;
a second bracket removably coupled to the guardrail and laterally offset from the first bracket;
a support member coupled to the first bracket and the second bracket and extending laterally between the first bracket and the second bracket;
an anchor slidably coupled to the support member such that the anchor is repositionable laterally along the support member; and
a fall limiter coupling the anchor to a harness,
wherein the support member is positioned above the guardrail and received by the lateral aperture of the first bracket, and wherein the support member is substantially centered about a lateral axis that extends through the lateral aperture.

14. A platform assembly, comprising:
a platform defining a support surface for an operator, the platform including a guardrail fixedly coupled to the support surface;
a first bracket removably coupled to the guardrail, the first bracket defining (a) a first recess that receives a vertical member of the guardrail and (b) a second recess that receives a horizontal member of the guardrail, wherein the first recess and the second recess extend substantially perpendicular to one another;
a second bracket removably coupled to the guardrail and laterally offset from the first bracket;
a support member coupled to the first bracket and the second bracket and extending laterally between the first bracket and the second bracket;
an anchor slidably coupled to the support member such that the anchor is repositionable laterally along the support member; and
a fall limiter coupling the anchor to a harness,
wherein the support member is positioned above the guardrail.

15. A method of providing a fall arrest system, comprising:
providing a harness adapter configured to be coupled to a harness worn by an operator;
coupling a first bracket to a first guardrail of a first platform such that the first bracket engages a front surface and a first side surface of the first guardrail;
coupling a second bracket to the first guardrail such that the second bracket engages the front surface and a second side surface of the first guardrail opposite the first side surface;
coupling a first end portion of a tensile member to the first bracket;
inserting the tensile member through an aperture defined by the harness adapter such that the harness adapter is repositionable along a length of the tensile member;
coupling a second end portion of the tensile member to the second bracket;
decoupling the first bracket and the second bracket from the first guardrail; and
coupling the first bracket and the second bracket to a second guardrail of a second platform.

16. The method of claim 15 , wherein the second end portion of the tensile member includes a threaded stud, and wherein coupling the second end portion of the tensile member to the second bracket includes:
inserting the threaded stud through a stud aperture defined by the second bracket; and
engaging a fastener with the threaded stud such that the fastener applies a force against the second bracket to tension the tensile member.

17. The method of claim 15 , wherein the tensile member is a first tensile member, further comprising:
decoupling the first bracket and the second bracket from the first tensile member;
coupling a first end portion of a second tensile member to the first bracket;
inserting the second tensile member through the aperture defined by the harness adapter such that the harness adapter is repositionable along a length of the second tensile member; and
coupling a second end portion of the second tensile member to the second bracket,
wherein the length of the first tensile member is different than the length of the second tensile member.

18. The fall arrest system of claim 6 , wherein a pin runs through the boss aperture, the first support aperture, and the second support aperture, coupling the slot to the boss.
