Electric overhead traveling cranes or EOT cranes are a common type of overhead crane, also called bridge cranes. They consist of parallel runways, much akin to rails of a railroad, with a traveling bridge spanning the gap. [1] EOT cranes are specifically powered by electricity.
Enclosure comparison with normal wiring & with busbar system. Electrical busbar systems [1] (sometimes simply referred to as busbar systems) are a modular approach to electrical wiring, where instead of a standard cable wiring to every single electrical device, the electrical devices are mounted onto an adapter which is directly fitted to a current carrying busbar.
In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks .
Member companies represent industry leaders in the overhead crane market, serve the United States market from operations based in the United States, Canada, and Mexico. CMAA, formerly the Electric Overhead Crane Institute, is an incorporated organization of leading electric overhead traveling crane manufacturers in the United States and an ...
The busway is open at the bottom, and a movable collector assembly "trolley" is used to connect between the fixed bus bars in the busway and the cable connected to moving equipment. [4] Bus ducts are building service penetrants that are required to be externally firestopped where they penetrate fire separations required to have a fire ...
Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.
Single Girder Overhead Crane. The single girder type overhead crane is the most common overhead crane. It is generally used for light applications, normally up to 10 tonnes. Double Girder Overhead Crane. The double girder overhead crane structure is used for heavier applications up to 125 tons and reaching over 100 feet of span.
A smaller type of isolated-phase bus is manufactured for direct-current circuits; this may be used in the field circuit of a generator. Currently, the isolated-phase bus world record current is 52,000 A, for bus manufactured by Alstom Power (since 2015 General Electric Power) and installed at the Civaux Nuclear Power Plant, in 1997.
