SUMMARY

The discussion focuses on calculating the lifting force generated by a motor with a torque of 16,000 N-M, utilizing a gear reduction ratio of 7.51. The motor drives a drum with a diameter of 1 meter, using a rope with a diameter of 0.0508 meters. The block and tackle assembly consists of 10 lines, comprising 5 stationary upper sheaves and 5 lower moving sheaves. The calculation of the lifting weight assumes no efficiency losses.

PREREQUISITES
  • Understanding of torque and its units (N-M)
  • Knowledge of gear reduction ratios
  • Familiarity with block and tackle mechanics
  • Basic principles of force and weight calculations
NEXT STEPS
  • Calculate the effective lifting force using the formula: Force = Torque / Radius
  • Research the impact of gear reduction on lifting capacity
  • Explore the mechanics of block and tackle systems
  • Learn about efficiency losses in mechanical systems
USEFUL FOR

Engineers, mechanical designers, and anyone involved in lifting mechanism design or motor applications will benefit from this discussion.

Gentlemen please.
I am trying to find out how much a motor can lift through a gear reduction to a drum connected a block and tackle assembly.
The motor can develop 16K N-M of torque, through a gear reduction of 7.51, turning a drum having a diameter of 1 meter, using 0.0508 meter rope. there are 10 lines in the block and tackle assembly ( 5 stationery upper sheaves and 5 lower moving sheaves).
How do I calculate how much wieght this will lift?

Assuming no losses due to efficiency :)
