SUMMARY

The discussion centers on calculating the appropriate motor size required to move a 12-ton cart on rails at a speed of 5 meters per minute. Key factors include the gearbox ratio, wheel size of 230mm, and the flat surface on which the trolley operates. The maximum load of 12 tons is confirmed as the weight the trolley will carry. Participants emphasize the importance of determining the gearbox ratio to accurately calculate the necessary torque from the motor.

PREREQUISITES
  • Understanding of torque calculations for motor applications
  • Familiarity with gearbox ratios and their impact on motor performance
  • Knowledge of wheel size and its effect on load movement
  • Basic principles of mechanical systems and load dynamics
NEXT STEPS
  • Research how to calculate torque requirements for a motor based on load and speed
  • Learn about selecting appropriate gearbox ratios for specific applications
  • Investigate the effects of wheel diameter on motor performance and load movement
  • Explore mechanical design principles for trolley systems on flat surfaces
USEFUL FOR

Engineers, mechanical designers, and anyone involved in the design and operation of motorized trolley systems, particularly in industrial settings.

Need to calculate motor size to drive skip dolley system. have the following:
Frame on 6 wheels. Gearbox/motor driving middle pair of wheels.
Total mass 12t
Need to move trolley @ 5m/min

Any thoughts where to begin?

Well I'll take a stab at it,

whats the ratio on your gearbox?

size of wheels?

is the trolley for use on a flat surface or how steep are the biggest inclines?

What sort of load will it be carrying? is 12t the maximum load or just the weight empty?

Once you know those, I think we can figure out the maximum torque needed from your motor.
 
Wheels = 230mm
flat surface
max load = 12t
ratio on gearbox=? Don't know the ration since we need to source it still...
