PAYBACK ASSESSMENT OF ALTERNATIVE SYSTEM OF ELECTRICAL POWER TRANSMISSION

Transmission tower manufacturing industry is engaged in the design,
development, manufacturing, supply and construction of overhead transmission lines for
Turnkey projects including manufacture of substation structures microwave tower and
similar structure. There are different types of cranes used in transmission tower company
Such as goliath crane, EOT crane and mobile crane to transfer raw materials ,semi-finish
and finish products from one place to another place. The installation of goliath cranes are
in raw and dispatch yard and it is used to transfer raw materials from raw yard to different
machine in fabrication shop also it transfer finish good from dispatch yard to different
transport vehicles like container, trailor or truck etc.

Draw back in the existing system of goliath crane means high breakdown occurs due to damages of supply current trolley cable therefore high maintenance and production cost is involved and after every two years supply current trolley cable is replaced by new one. In this investigation a complete though is given as regards how to minimize breakdown and production loss by implementing busbar system in place of existing system of goliath crane .Bus-bar system is used to supply 3- phase current to different motors of goliath crane instead of cable trolley system
