used together to form a bridle hitch for hoisting an objectA sling with two
legs used to lift a 1,000 pound object will have 500 pounds of the load on
each leg when the sling angle is 90 degrees. The load stress on each leg
increases as the angle decreases; and if the sling angle was 30 degrees lifting
the same 1,000 pound object, the load will be 1,000 pounds on each leg. Try
to keep all sling angles greater than 45 degrees; sling angles approaching 30
degrees are considered extremely hazardous and must be avoided at all cost..
