• MAIN FRAME:
  M.S. Plates are fastened with number studs to withstand the load of the different independent units attached to it.
  
• WIRE ROPE:
  Hoisting rope comply with the Indian standards. The leading rope taken by the Drum, does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six.
  
• ROPE DRUM:
  Grooved Drum, Seamless Pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimise abrasive wear is provided. Drum Shaft revolves on Ball Bearings for ensuring smooth running.
  
• ROPE GUIDE:
  Rope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may not uncoil even when the Hoist is in unloaded condition.
  
• MOTOR:
  Hoist Motor is an HTSC parallel rotor machine. Specially rated for Hoist duty, with minimum 40% CDF Rating and class B insulation. The unit is an IP 54 dust and damp proof enclosure, flange-mounted to the main frame of the Hoist. When creep speeds are required same is achieved by way of DC Clutch and Pony-Motor.
