example one

[0066]Detailed below is an example of the general process flow of a customer ordering a modular pedestrian bridge, for purchase or lease, for example.

1. A customer contacts a bridge supplier with its general requirements. The customer may require a temporary modular bridge for a specific event, or perhaps a permanent structure. Typically, the customer will provide the approximate dimensions needed for the desired bridge, such as length, approximate tower height, terrain, available space for stair layout and available foot print.

2. The supplier pre-assembles and pre-packs the spans as necessary, preliminarily designs and pre-packs the necessary components on and in the flat bed chassis, as shown in FIGS. 12-14, 15 and 16-17, as well as pre-plans the assembly necessary at the work site. Advantageously, it is more efficient to pre-plan and pre-assembly components, at the suppliers facilities, where the personnel and expertise are resident, prior to going in the field for assembly.

Abstract

A modular pedestrian bridge (10) is disclosed. In its simplest form, the bridge (10) includes: a span module (12) having a tunnel (14) sufficient to allow pedestrians to travel through the tunnel (14), the tunnel (14) being defined by a floor (16) and a top (18), defining a height (20), sides (22) defining a width (24) and upper and lower connectors (26) and (28), a tower module (30), a stair assembly (32), the tunnel (14) having sufficient dimensions to allow the tower module (30) to be telescopically fit into the tunnel (14) and the span module (12) being adapted to fit on a chassis or flat bed truck of a vehicle. The bridge (10) is configured to simplify assembly and disassembly and is adapted to fit on a chassis, flat bed truck and the like. The span module (12) is dimensioned, such that it does not have special freight requirements, possibly triggering state and federal escort laws for extra wide or long loads.

Description

FIELD OF THE INVENTION[0001]This invention relates to bridges, and more particularly to a modular pedestrian bridge and system.BACKGROUND OF THE INVENTION[0002]It is advantageous to provide the ability for pedestrian and handicap traffic to safely and comfortably cross over a potentially dangerous area, such as a road, creek, railroad tracks, construction site or the like. Pedestrian access of this type is frequently required at popular or well attended events, such as sporting events like automobile racing, golf tournaments and marathons, for example. Existing known pedestrian bridges are generally cumbersome and time-consuming to erect, difficult to transport and not particularly portable or repeatable.[0003]There is a need for a modular pedestrian bridge and its components that: allow for flexibility in configuration; comprise modular components that are easy to align, assemble and disassemble, and are portable and transportable; provide stair and height flexibility and adjustmen...
