Benefits of technology

The collapsible hanger design enhances miner safety by eliminating the need for manual cable removal, reduces the risk of injury, and allows continuous coal extraction without stopping production, as the cable can be wound up by Mobile Roof Support machines without additional handling steps.

Problems solved by technology

Often, though, even when miners are working with MRS's, the miners need to release the cable from the hangers by hand before the MRS can wind the cable.
Miners are encumbered and endangered in their work by having to enter the Red Zone in order to retrieve the cable from the hangers.
They are endangered by the possibility of the roof falling on top of them.

Embodiment Construction

[0020]In one embodiment of the present invention provides for a collapsible hanger (1) that uses the ability of gauged wire to permanently bend under pressure to release a cable from the hanger (1) without miners having to place themselves near the hanger and / or in harm's way. FIGS. 1 through 3 illustrate three embodiments of collapsible hangers (1) according to the present invention. The upper hook (10) hooks into or through the hole of a roof plate or the roof of the mine (not shown).

[0021]The words “roof” and “ceiling” are used interchangeably herein. Essentially, the upper hook (10) of a collapsible hanger (1) hangs on or in the roof plate or ceiling of a mine. The hanger (1) can hook directly into the roof or ceiling of the mine or it can hang from another apparatus, which is secured to the mine roof or ceiling. Often times, as shown in FIG. 4, a roof plate (40) is secured to the mine ceiling. These roof plates (40) are designed so that a hanger (1) can connect to them (40) and...

Abstract

The present invention comprises a collapsible hanger for supporting, among other things, cables from the ceiling of mines. The collapsible hangers of the present invention allow the cables to fall to the floor when tension, pressure, and / or weight is applied to the hangers, either directly or indirectly.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This patent application is a Continuation of U.S. non-provisional application Ser. No. 11 / 026,593, titled COLLAPSIBLE HANGER, filed on Dec. 30, 2004, which claims benefit of U.S. provisional application Ser. No. 60 / 623,305, titled COLLAPSIBLE HANGER, filed on Oct. 29, 2004, both are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Generally, in mining, miners must install and remove hangers from the ceiling of the mines. These hangers support various types of cables and wires, electrical or otherwise, etc. Often these hangers and cables are installed and removed by hand. Historically, to remove the cables, miners walked beneath the hangers and removed the cable from each hanger, or removed the cable and the hanger from the ceiling of the mine. All of this is and has been done by hand.[0003]A Mobile Roof Support (MRS) is a machine used to perform full pillar extraction methods in underground coal mines. The use of MRS's eli...
