Bed Weight and Lifting Capacity

  • Motors advertised at 84 oz in or 5.25 in lb
  • with 1/2 diameter pulley, that is about 20 lb driver force - about right.
  • Total lift is 40 lb from both sides
  • Weight of bed - 7.5 lb for top and bottom, 3.5 lb for sides. Rods - .7 lb per foot, we have 3 feet - 2 lb more. Insulation - maybe 1.4 lb / cu ft [1]. We have 1/6 cubic foot, so only a quarter pounder of fluff.
