Calculations for moments on H4 turntable with Dee4 ==================================================
Dee4 moment = 2.8 m-tonnes beams on right moment = 0.504 m-tonnes Dee4 table on right moment = 0.63 m-tonnes
Long beam (B) on left moment = 0.3795 m-tonnes Cross pieces to (B) on left moment = 0.1683 m-tonnes SM support on left moment = 0.317088 m-tonnes 2 diagonal beams on left moment = 0.143608 m-tonnes 2 vertical beams on left moment = 0.2013 m-tonnes
Right 3.934 m-tonnes Left 1.2098 m-tonnes Difference 2.7242 m-tonnes on right
Compensating weight on blue frame at (B) at 1.65m 1.651 tonnes
