Abstract
A power rail and guidebeam assembly (10) for use in a vehicle transportation system conveys electric power to travelling vehicles in the vehicle transportation system. The power rail and guide beam assembly includes a guidebeam (12) having an H-shaped body (14). The body of the guidebeam (12) is defined by two flanges (16, 18) that are interconnected by a web (20). A mounting bracket (30) is secured to the web, with the mounting bracket (30) including a base and at least one ear (54). A power rail (26) is secured to the at least one ear (54) of the mounting bracket. The power rail is electrically insulated from the guidebeam (12) by the mounting bracket (30). The guidebeam (12) is preferably grounded to the earth.
Claims25
A power rail and guidebeam assembly, comprising:
- a guidebeam having an H-shaped body, with the body defined by two flanges interconnected by a web;
- an insulating mounting bracket fixedly secured to the web, with the mounting bracket having a base and at least one ear;
- and
- a power rail connected to the at least one ear of the mounting bracket,
- wherein the power rail is electrically insulated from the guidebeam by the mounting bracket.
A vehicle transportation system, comprising:
- an electrically powered vehicle having a vehicle body and a plurality of driving wheels connected to the vehicle body;
- a guide-frame attached to the vehicle body, with the guide-frame having a plurality of depending guide wheels and a power contact;
- and
- a power rail and guidebeam assembly coacting with the guide wheels, with the power rail and guidebeam assembly further comprising:
