Abstract

A bearing retainer plate for fall restraint equipment made from a single, continuous piece of sheet metal, where the metal is lasered, cut, and/or butterflied to define a plurality of apertures. A bearing, preferably possessing a self-centering characteristic, is inserted into one of the apertures, while an adapter or bracket for an over-travel stop is inserted into another. A foot lock stud is inserted into another aperture defined by the bearing retainer plate and welded into place. The piece of metal may also define apertures configured to receive fasteners for attaching the plate to the fall restraint equipment, such as to a support structure of a gangway.

Claims

1. A gangway comprising:

a support platform;

a support structure connected to the support platform in a manner that allows the support structure to rotate with respect to the support platform;

a piece of metal connected to the support platform;

a bracket configured to receive a stop inserted into at least a first aperture defined by the piece of metal; and

a foot lock stud inserted into a second aperture defined by the piece of metal.

2. The gangway of claim 1 further comprising a bearing inserted into a third aperture defined by the piece of metal, wherein the support structure defines a pivot aperture and the bearing coaxially aligns with the pivot aperture in a manner that allows the support structure and piece of metal to rotate with respect to the support platform.

3. The gangway of claim 2 wherein a rod is inserted through the pivot aperture, the bearing, and the support platform in order to pivotally connect the piece of metal, the support structure, and the support platform.

4. The gangway of claim 1 further comprising a handrail connected to the platform support, wherein the stop comes into contact with the handrail when the gangway is retracted into a vertical position.

5. The gangway of claim 1 wherein a portion of any load applied to the bracket or foot lock is dispersed to the piece of metal.

6. A bearing retainer plate for a gangway comprising a single, piece of metal defining first and second apertures, wherein the first aperture is configured to receive an over-travel stop and the second aperture is configured to receive a foot lock stud, and a third aperture configured to receive a bearing, wherein the gangway and bearing retainer plate are rotatable between a deployed position and a stored position.
