Problems solved by technology

Additionally, the contacting metal plate pulling the cable creates friction, increasing tension and resistance
The combination of friction-induced heat and strain on snagged cables (e.g. splices) greatly reduces trailing cable life

Abstract

The invention relates to a low friction sheave bracket. An electrically powered mining vehicle including a frame rollingly supported on a surface for movement over the surface. An electric motor is coupled to the frame for proving power to the vehicle. A cable is electrically coupled to the electric motor for supplying electricity thereto and a cable management system is coupled to the frame and arranged to receive and payout the cable as the vehicle moves over the surface. A sheave bracket is coupled to the frame and arranged to direct the cable into the cable management system and includes a lower plate arranged substantially horizontally, a plurality of vertical rollers that are coupled to the lower plate and are arranged to guide the cable into the cable management system, and a horizontal roller that is coupled to the lower plate and arranged to elevate the cable above the lower plate.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 513,858, filed August 1, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to mining shuttle cars, and more particularly, the present invention relates to pulley brackets for mining shuttle cars. Background technique [0004] Mobile electric machines, such as shuttle cars used to carry mining material in underground mines, have electric motors connected by cables to a power source. As the machine moves backwards, forwards, and around corners, the cable is wound onto and paid out from the reel. The cable extends from the rear side of the shuttle car and, sometimes, runs along the side of the shuttle car when the shuttle car is moving rearward, or runs straight back from the shuttle car when the shuttle car is moving forward. As the shuttle car moves around corners, the cable runs along the r...
