## Abstract

A pre-assembled walkway is provided, comprising an elongated walkway pan, a side railing subassembly, and a plurality of mounting brackets pivotally connecting the side railing subassembly to the walkway pan. The side railing subassembly comprises a plurality of vertical supports and handrails secured to tops of the vertical supports. The walkway is in a collapsed position when the side railing subassembly is pivoted in a first direction to the walkway pan with the vertical supports substantially parallel to the walkway pan and is in an erect position when the side railing subassembly is pivoted in a second, opposite direction with the vertical supports substantially orthogonal to the walkway pan.

## Claims

### Claim 1

A pre-assembled walkway with two lengthwise sides and two widthwise sides, comprising:
an elongated walkway pan with two pan lengthwise sides and two pan widthwise sides;
a side railing subassembly, comprising:
a plurality of vertical supports; and
handrails secured to tops of the vertical supports;
a plurality of mounting brackets pivotally connecting the side railing subassembly to the walkway pan, whereby the walkway is in a collapsed position when the side railing subassembly is pivoted in a first direction to the walkway pan with the vertical supports substantially parallel to the walkway pan and is in an erect position when the side railing subassembly is pivoted in a second, opposite direction with the vertical supports substantially orthogonal to the walkway pan;
at least one removable toe board fastened to one of the pan lengthwise sides of the walkway pan; and
removable cross-braces fastened between the handrails and the walkway pan on both lengthwise sides of the preassembled walkway,
wherein the pre-assembled walkway is collapsible upon removal of the cross-braces and the at least one toe board.

### Claim 2 (depends on 1)

The pre-assembled walkway of claim 1, further comprising a mid-rail fastened to a mid-portion of each of the vertical supports on both sides of the preassembled walkway.

### Claim 3 (depends on 1)

The pre-assembled walkway of claim 1, further comprising a plurality of support beams transversally secured to an underside of the walkway pan.

### Claim 4

A method for assembling a walkway, comprising:
providing an elongated walkway pan with two pan lengthwise sides and two pan widthwise sides;
providing a plurality of vertical supports pivotally connected to the walkway pan;
providing handrails secured to tops of each of the vertical supports;
collapsing the walkway by removing a plurality of cross-braces affixed to the vertical supports and affixed to the walkway pan, and removing at least one toe board affixed to one of the lengthwise sides of the walkway pan;
pivoting the vertical supports from a collapsed position with the vertical supports substantially parallel to the walkway pan into an erect position substantially orthogonal to the walkway pan; and
securing the vertical supports in the erect position.

### Claim 5 (depends on 4)

The method of claim 4, further comprising fastening a mid-rail to a mid-portion of each of the vertical supports on both lengthwise sides of the preassembled walkway.

### Claim 6 (depends on 4)

The method of claim 4, further comprising affixing a plurality of cross-braces between the elongated walkway pan and the handrails.

### Claim 7 (depends on 4)

The method of claim 4, further comprising securing a plurality of transverse support beams to an underside of the walkway pan.

### Claim 8 (depends on 4)

The method of claim 4, further comprising providing the walkway pan, the vertical supports, and the handrails in a collapsed position at a first location and pivoting and securing the vertical supports in an erect position at a second location.
