Abstract

An ice bridge system for a cellular transmissions site assembled with a ladder frame section to support cabling laid on top of the and a ladder support with a preformed base for resting on a ground surface, a preformed set of mounting points for securing one or more sections of the ladder frame, such that the ladder frames mate end to end with each other and a structural support section between the base and mounting points to support the weight of the ladder frame and supported cables.

First claim

What is claimed is:

1. An ice bridge for a cellular transmissions site comprising:
a ladder frame section to support cables between an equipment shelter and a transceiver tower, the ladder frame section comprising a plurality of rungs and a pair of side rails connected to each other by the plurality of rungs, wherein a top of the ladder frame section is covered by a cover, and a bottom of the ladder frame section is uncovered; and
a ladder support securing the ladder frame section above a ground surface, the ladder support securing the ladder frame no more than approximately two feet above the ground surface, the ladder support comprising:
a preformed base for resting on the ground surface; and
a structural support fixed to the preformed base and extending away from the preformed base, a portion of the structural support adapted to support the ladder frame above the ground surface,
wherein the structural support is formed from metal and comprises a plurality of connecting points for attaching grounding wires.

2. The ice bridge of claim 1 , wherein the portion of the ladder support adapted to support the ladder frame above the ground surface comprises one or more mounting points for securing the ladder frame to the structural support.

3. The ice bridge of claim 1 , wherein the cover is removably connected to the ladder frame.

4. The ice bridge of claim 3 , wherein the cover has a non-slip surface applied to at least a portion of the top.

5. The ice bridge of claim 1 , wherein the ladder frame is curved horizontally through about 45 degrees or about 90 degrees.

6. The ice bridge of claim 1 , wherein the ladder frame is curved horizontally through about 90 degrees.

7. The ice bridge of claim 1 , wherein the ladder frame is curved vertically through about 90 degrees.

8. The ice bridge of claim 1 , further comprising a plurality of ladder supports and ladder frame sections.

9. The ice bridge of claim 8 , further comprising a hinged connector attached between two adjacent ladder frame sections.

10. A method of assembling an ice bridge at a cellular transmission site between an equipment shelter and a transceiver tower, the method comprising:
installing a ladder support on a ground surface, comprising:
securing a preformed base of the ladder support into the ground surface with fasteners inserted through holes in the preformed base and into the ground surface;
securing a structural support of the ladder support to the preformed base such that the structural support extends away from the preformed base, wherein a portion of the structural support is adapted to support a ladder frame section above the ground surface; and
grounding the structural support to the earth, wherein the structural support is formed from metal and comprises a plurality of connecting points for attaching grounding wires; and

installing the ladder frame section to the structural support of the ladder support such that the ladder frame section is above the ground surface, the ladder frame section comprising a plurality of rungs and a pair of side rails connected to each other by the plurality of rungs, wherein a top of the ladder frame section is covered by a cover, and a bottom of the ladder frame section is uncovered,
wherein the ladder support secures the ladder frame no more than approximately two feet above the ground surface.

11. The method of claim 10 , wherein a plurality of ladder frame sections and ladder supports are installed to form the ice bridge, and wherein the method of assembling the ice bridge further comprises:
installing a hinged connector between two adjacent ladder frame sections.
