Outrigger-equipped roof-mounted fall-arrest safety device

A fall-arrest safety device for mounting onto a roof having a peak and two opposite surfaces and for attaching at least one safety tether, the safety device comprising:

• a main frame having two lower end portions defining main frame opposite ends, an upper intermediate portion extending between the lower end portions, and a transverse opening extending side-to-side therethrough and formed between the two lower end portions;
• at least one wheel that rotates relative to the frame;
• at least two end feet each one extending from a respective one of the frame lower end portions;
• at least one tether attachment configured to permit the safety tether to be attached thereto for worker safety;
• an outrigger assembly including an outrigger frame pivotally mounted to the main frame and defining two outrigger frame sides and at least two side feet each one positioned at a respective one of the outrigger frame sides;
• and
• a mechanical stop assembly configured to selectively limit pivotal movement of the outrigger frame by mechanical interference,
• wherein in a stored position, the outrigger frame is pivoted into general alignment with the main frame, and
• wherein in a use position, the main frame transverse opening receives and the main frame straddles the roof peak, and the outrigger frame is acutely angled relative to the main frame and is blocked from pivoting out of the use position and toward the stored position by the mechanical stop assembly, with one of the main frame end feet contacting and supported by a respective one of the roof surfaces and one of the outrigger frame side feet contacting and supported by a respective opposite one of the roof surfaces to cooperatively produce a clamping force on the roof opposite side surfaces to securely mount the safety device in place.
