POWERED SWINGING LOAD

RECOMMEND STANDARD SERIES 50

Let W = 500#, W1=55#, H=6.7", D=10" F=100#, T=955 inch lbs., Ø=1.047 radians.

 E = W x H + F x D
E = (500)(6.7) + (100)(10)
E = 4350 IN. LB. ENERGY

IF THE INPUT POWER IS TORQUE THRU AN ANGLE:

 IF THE WEIGHT OF THE ARM (W1) IS GREATER THAN 10% OF W:

E = W x H + T x Ø
E = (500)(6.7) + (955)(1.047)
E = 4350 IN. LBS. ENERGY

 E = (W x W1)x H + T x Ø
E = (500 + 55) (6.7) + (955) (1.047)
E = 4718.5 IN. LBS. ENERGY
