The invention provides a roof lifeline anchor device for attachment to and between adjacent roof trusses of a building. The anchor comprises an elongated beam having roof truss attachment structure located at each end and a lifeline attachment structure centrally located along the beam. The device attaches to roof trusses in such a manner that forces exerted on lifelines connected thereto will be directed through the anchor into the truss assemblies and be spread across two or more trusses. In the preferred embodiment, the device is fabricated from a steel box beam and the truss attachments are stirrups fabricated from sheet steel sized to fit over the beams of a roof truss. This preferred form is fitted to the truss assemblies from beneath and secured to the trusses by bolts passing through the stirrups and the truss beams so that forces on the lifelines tend to pull the anchor upward against the truss beams.
A roof lifeline anchor for attachment to and between adjacent roof trusses of a building, comprising an elongate beam having first and second ends, truss attachment means at said first and second ends and lifeline attachment means positioned on said beam substantially midway between said first and second ends, wherein said truss attachment means comprises elongated stirrups each having a bottom wall and two upstanding parallel spaced side walls to receive said roof trusses and further comprising means to attach said members to said trusses.
A roof lifeline anchor for attachment to and between adjacent roof trusses of a building and comprising an elongate beam having first and second ends, roof truss attachment means, and lifeline attachment means located midway between said first and second ends;
A roof lifeline anchor for attachment to and between adjacent roof trusses of a building and comprising an elongate beam having first and second ends, roof truss attachment means, and lifeline attachment means located midway between said first and second ends;
A roof lifeline anchor for attachment to and between adjacent roof trusses of a building comprising a first elongated hollow beam having a roof truss attachment means on one end, a second elongated beam having a first end telescopic within said first beam and having a roof truss attachment means on a second end, each beam having apertures perpendicularly therethrough, the apertures of said second beam being alignable with the apertures of said first beam, and a lifeline attachment means adapted to be inserted into said apertures when aligned and be secured therein whereby said first and second beams are maintained in a specific telescopic relationship and wherein said roof truss attachment means comprises elongated stirrups each having a bottom wall and two upstanding parallel spaced side walls to receive said roof trusses and further comprising means to attach said members to said trusses.
