Winch Drum Torque calculation.
Winch Drum Torque calculation.
(OP)
Good Day to you all,,
May I ask some question. I hope anybody can help me here. I confused to calculate Drum torque. Drum weight is 200Ton. Pull force at layer dia 5.6m is 20Ton. As my option, Torque is 20Tonx 2.8m= 549kNm..But I found 607kNm in specification. I can't clarify which one is correct. If I calculate drum torque, do I need to consider drum weight(200Ton) also or rolling resistance? Which formula is applicable ?
Thank in advance..

Yes, consider rolling resistance.

Not uncommon, just a guess.
