CIM peak power = 321 W
321W * 4 = 1284 W
Assuming gearbox efficiency of something extremely conservative like .5
1284W*.5 = 642W
25 lbs * 10 ft (tallest most bedroom ceilings would be) = 339 joules
Power = Work /Time
Time = Work / Power
339 Joules / 642 W = .53 seconds
This means that at half of peak power 4 CIMS will lift a TV of 0 height from your floor to your ceiling in .53 seconds. I guess my point is, how did you decide you needed 4 CIMs for this job?
