I just joined the groups and must say it is refreshing that everyone is so willing to help out people who have not been a part of theatre very long.
I come with a question or questions about casters/wagons and how to calculate the load and how many casters are needed.
I'm working on the set of The Addams family. I one (two technically) large set pieces that need to be moveable. Two set of stairs. Both with a total run of 14 feet and total Rise of 8foot 6 iniches.
To move them off stage or course stage I need to make them manageable. For 4-8 Student to move.
So my questions are? Does anyone have any suggestion as a rule of thumb number of casters for something that weighs in the ballpark of 300-500 lbs and is 14 feet Long , 8 foot 6 inches high and about 4 foot wide.
Thank you for pointing me in the correct direction. I am still working on this. I guess I need to calculate the psf for this will the assumed weight of 500lb over a 14x4 wagon.
14 foot x 4 foot = 56sftso500 lb divided by 56 sqft = 8.92pft2 I think that is correct.Then figuring out the Tributary area and so on and so forth.Let me know if I'm barking up the wrong tree here..Thanks Tracy
Welll we build the stairs. Somewhere in the ballpark of 375lbs each.After the proper calculations and buying the 3P20PST casters from Access caster, the stairs moved flawlessly.uploading a vidoe of two of the smallest kids i could find to move it.
Thanks again Tracy!
