Hello,
So I am in the process of designing a stair climbing electric handcart/dolley capable of lifting around 500 lbs {Washer/dryer or Refridgerator} up stairs. The idea was to use an electric motor, preferably DC for HighTorque Low Speed and for my powering options. The idea was to use the 3-wheel stair climbing system already in existence, but to put a sprocket on a solid axle, and use a chain hooked to an electric motor to turn the 3-wheel system therefore, climbing stairs. Even better if I could use reverse on the motor to control descent as well. The class I am in is Intro to Engineering Design, and no attention has been put toward any physics calcs so Everything I am learning for this project has been from google.
If anyone could help Steer me in the right direction It would be a big help. I am fresh out of the Army so I have forgotten a lot of the technical info from HS days, and being a Combat Engineer(SAPPER) doesn't help me with this. If the cart needed blown up, Icould do that no problem! lol If anyone out there could provide me with good websites to help break down some of these torque calculations, and any tips about what else to include in my design calculations so hopefully my first shot at prototype is close to success, all would be greatly appreciated. If someone has a good idea for a type of electric motor worth using on this project, also would be a help. I am leaning toward a winch motor from an ATV hoping it can handle a 300-500lb capacity without burning it out. Once again, this is for a school project, my first engineering class which seems to emphasize more on AutoCAD rather than Physics. Thank you all in advance!
