the pipe section is starting horizontal at grade and being tailed into vertical position as shown in drg. therefore wire sling angles move from 0-90 degrees throughout lift. wire slings will be cradled round trunnion therefore as good as parallel after accounting length to the spreader beam...
What I am after Mike is the force applied on each trunnion from the 18t pipe throughout the lift. Moss seems to cover this from what I can take from it.
Thanks Mike
Been reading some interesting material in the Pressure Vessel Design by Moss.
But the calculations seem pretty minimal especially for calculating the load at any angle.
hello
I am looking for an insight for trunnion capacities during lifting operations in the static state during the 0-90 degree change in wire rope sling angle.
Have been looking for calculations to start getting my head round this but so far have come up short
Any help apprecieted
