Abstract
An anchorage safety device for steelworkers. The safety device is configured to be slidably coupleable to a flanged structural beam to which a lanyard may be attached to secure a workman against a fall. The anchorage device includes an elongate cross-member having a plurality of apertures formed there-through to allow adjustment of the anchorage device to accommodate various beams, a lanyard attachment apparatus, affixed to the mid-point of the cross-member, for receiving a clip of a workman's lanyard; and opposed first and second clamps for coupling the device to the flange of a beam. The clamps include a ratchet pawl having first and second teeth for selectively engaging the cross-member apertures. The worker needs only one hand to release the ratchet pawl from the apertures by simultaneously applying pressure on an enlarged engagement surface of the ratchet pawl and a clamp housing surface that is opposed to the enlarged engagement surface. Since both forces must be simultaneously applied in opposite directions, inadvertent disengagement of the clamp from the cross-member is obviated.
