WebbMeasured from the rotating string weight, the pickup drag is usually vaguely greater than the slack-off drag. The magnitudes of torque and drag are related in any particular well; high drag forces and excessive torque loads usually occur together.

WebbStability on Flat Ground. We can first to determine the overturning moment if it is on level ground. This will be equal to 2000 lb * (13in+20in) = 66,000 in-lb. Next, the stability moment is 3000 lb * 31.27 in = 93,810 in-lb. You can see that the unit is stable by a significant margin by 29.6%.
