SpletThe load factor for the sling angle is taken from a load factor chart. Say two slings are lifting a load of 1000 lbs at an angle of 45 degrees. The load factor from the chart for a 45-degree sling angle is 1.414. Sling load force = (load weight / 2) * load factor (1000 lbs / 2) = 500 lbs 1.414 * 500 lbs = 707 lbs (sling load force) Spletthe “angle” of the choke (not the angle of the leg of the sling). If the load is hanging free, the normal choke angle is approximately 135 degrees. When lifting and turning a load using a choker hitch, it is not uncommon to have a severe bend at the choke. When a choker hitch is used at an angle of less than 120 degrees, you must reduce
