Traction

A good and efficient transport system is indispensable for economic growth and national development. Both Semiconductor and Equipment Divisions work in the form of Interdisciplinary co-operation and offer custom-built solutions. They have a long standing experience in surface and underground transport systems. New transport systems require updating of technology and Hirect's experience has grown steadily with the absorption of new technology to keep pace with demand and involvement in important transport projects of the Railways, Mass Transit Projects and Metropolitan Transport Systems.

Traction duty applications require special design considerations, viz,

Intermittent duty cycles with periodic overloads
Shock and vibration withstand capabilities
Size and cooling restrictions
