5. EOT Crane Parts
Cranes are designed as per IS 3177 (workshop duty) & IS 4137 (steel Plant), it consists of following part:
Bridge (Girder): Box Type made up of MS plates, it can also be manufactured by beam for small capacity cranes.
End Carriage: Box Type made up of MS plates, it can also be manufactured by C-Channel for small capacity cranes.
Wheels: Forged items, made up of C55Mn75 material
