the OP needs 1,469,000 gm-cm of torque to balance the torque presented by the load (90 lbs or about 41 kg at 35 cm)
clearly more is needed to cause some angular acceleration to get started, then 1,469,000 gm-cm
is needed to maintain whatever angular velocity was achieved.
with the 180 kg cm servo motor described, there is 180,000 gm cm of torque
if you put in a gear ration of 10 to 1, you will boost the torques to a little less than 1,800,000 gm cm
(less because of the need to also rotate the gears and overcome axle friction etc, and for the twist in the drive shaft)
lets say that motor and gear set is enough. because of the 10 to 1 gear ratio, the angular acceleration will be 1/10th what
it might have been, had there been no need for gears.
since the motor and gears are only marginally able to exert enough torque, the lift rate will be painfully slow.
pulleys and ropes introduce the same sort of extra losses - rotating the pulleys, axle friction,
rope stretch (different materials will have different stretch, but there's losses in any case)
so, OP, what other things are going on in this project that have a bearing on the question?
