CRANEAGE - SLINGING: BASICS PAGE 21 GOOD SLINGING PRACTICE BASIC RULES ... 3 3.1. KNOW WHAT THE "INCLUDED ANGLE" IS ALL ABOUT. You know the weight of the load to be lifted. You have estimated the load's centre of gravity. You know what loads the slings can carry. You have information on the different types of slings. You are all set to lift, then. Right? No! There is still one very important factor to take into account - the "Included Angle" of the slings. Having the angle of the slings is so important that it gets a section all of its own. The included angle is the angle between the two legs of a sling system. The greater the included angle between sling legs, the less load can be lifted. If a single sling is taking a load vertically, the load on that sling is equal to the load weight. That's quite simple, and certainly sounds logical. 1,000 kg It may sound odd, but if a sling has an angle between the sling legs of 150°, each sling leg will have a load equal to twice the total load weight. For a load of 1,000 kg, each sling will have a load of 2,000 kg. Sling load = 2,000 kg 1,000 kg Incl. angle = 150° Should that angle increase to 170°, each leg will be subject to a load that is six times the total load weight. For a load of 1,000 kg, each sling will be loaded with 6,000 kg. Sling load = 6,000 kg 1,000 kg Incl. angle = 170°
