Abstract
The present disclosure sets forth a safety device for scaffolding so that workmen can climb up or down on the exterior of the scaffolding in safety. The apparatus includes an outwardly extending curving davit having an elevated and radially outwardly extending end supporting, at an eyelet, a fall arrester. The fall arrester is anchored with a hook and an eyelet and has an elongate cable of adequate length extending down to a hook connecting with a D-ring on a body harness for a user. If the user falls, the fall arrester sets a brake preventing the cable from extending, thereby interrupting the fall of the workman.

In combination with scaffolding mounted alongside a building for erection in sequence in a plurality of vertically spaced sections and having vertically extending outer tubular legs, the scaffolding including horizontal planking for supporting a workman and arranged for disassembly and mounting at increased heights of the scaffolding upon addition of an upper section of scaffolding;
- fall protection apparatus comprising a davit mounted on a selected outer tubular leg for adjustable vertical movement along said selected leg and positioning at a desired vertical location adjacent said planking on an upper section of said scaffolding;
- said davit including a vertical portion extending in parallel relation to said selected outer tubular leg on the planking, and an upper curved end portion extending outwardly from said vertical portion at an angle between 20 degrees and 80 degrees between and extending outwardly from said scaffolding between about 8 and 30 inches;
- a reinforcing member secured between said vertical portion and said curved end portion across the angle between said vertical portion and said curved end portion;
- a gusset plate secured to said curved end portion adjacent the extending end of said curved end portion and extending downwardly from said curved end portion;
- an eye extending through said gusset plate;
- a pair of clamping devices spaced vertically from each other for releasably clamping said vertical portion to said selected outer tubular leg to permit sequential adjustment of said davit at selected heights along said outer tubular leg for positioning said davit adjacent said planking on the upper section of said scaffolding;
- a body harness;
- and
- a fall arrestor positioned outwardly of said scaffolding and extending between said eye and said body harness for supporting the workman from said davit.
