Lead Screw diameter for lifting 200Kgs

AI Thread Summary
For lifting a weight of 200 kg using a lead screw, a diameter of around 1 inch (25 mm) is suggested as a good starting point, depending on the length for rigidity. Trapezoidal threads and nuts are being used in the application. It's recommended to consult suppliers like Nook Industries and Thomson Linear for specific specifications and recommendations. A smaller screw diameter could suffice for a one-time lift but may lead to quicker wear. Proper specifications are crucial for ensuring durability and effectiveness in the application.

Hi
I one of my application i am using the lead screw arrangement to lift 200kg weight using handle
I used trapezoidal thread and nut.
Could anybody suggest the diameter required for lifting the weight of 200kg
 
Engineering news on Phys.org
Look up "Nook industries", They make lots of lead screws, and would have specs for them... Depending on the length (for rigidity) 1" / 25mm would be a good starting point

Thomson Linear is another
 
Definitely look up recommendations and specifications from a good supplier. If you want to lift the load once you can get away with a much smaller screw diameter (and therefore smaller thread area), at the cost of rapid wear out.
 
Thanx, I will look into that and get the specifications and will get back if I need some more details

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
