Appl. No.:

12/930488

Inventors:

Gary Graham - Lewisville NC, US
Matthew Casey - Goldsboro NC, US

International Classification:

F16M 13/00

US Classification:

2482911

Abstract:

A cantilever assembly includes a cantilever arm having a pair of longitudinal fastening channels with a corresponding pair of slots in communication with the fastening channels. An attachment bracket features a connector portion and a pair of spaced leg portions defining a seat there between with each leg portion having at least one aperture. The leg portions also each have an inner surface featuring an elongated groove with each being in communication with a corresponding one of the apertures. The elongated grooves are positioned in alignment with the slots of the cantilever arm when the cantilever arm is positioned in the seat of the attachment bracket. Tee bolts having a shaft portion and an oblong head portion movably pass through the apertures of the attachment bracket with the oblong head portions pivotable between a first orientation where they may be positioned within the elongated grooves of the attachment bracket and passed through the slots and into and out of the fastening channels of the cantilever arm, and a second orientation where they are secured within the fastening channels of the cantilever arm.

Abstract:

A safety monitoring system for a catenary system that includes an overhead wire, a support pole and a counterweight attached to the end of the overhead wire and suspended by the support pole. The catenary safety monitoring system includes a temperature sensor for detecting an ambient temperature, a position sensor for detecting a position of the counterweight and an electronic controller. The electronic controller compares a detected position of the counterweight with a predicted position determined by the electronic controller using an ambient temperature from the temperature sensor. A message transmitter provides a warning to a user if the detected position of the counterweight is not within a predetermined percentage of the predicted position.
