  • Rope Drum: The rope drum is made from sturdy seamless pipe or fabricated from steel plates and is grooved to accommodate the wire rope up to the full length without over winding. The ratio of drum dia. to wire rope dia. is such that it reduces the wear & fatigue. The drum shaft revolves in ball bearings, ensures smooth running for long period.

  • Wire Rope: Tested quality, 6 X 37 construction special plough hemp core flexible steel wire rope , having safety factor of 6 for class II and 7 for class III duty is provided on the hoist.
