Webchoke, there is a reduction in rated capacity. This is reflected in the choker rated capacity tables. Another reduction that must be considered is due to the “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 Web1,000# capacity per sling 866# capacity per sling 707# capacity per sling 500# capacity per sling The figures above reveal that as the sling angles decrease, the tension in the sling legs increases, resulting in a greater load on each leg of the sling – and that reduces lifting capacity. Conversely, as the sling angle
WebJan 14, 2024 · Due to stresses created at the choke point, a choker hitch reduces the lifting capacity to 75-80% of what it is capable at in a single leg vertical hitch. The least amount of capacity reduction occurs when the angle of choke is 120° or greater. Any less than 120° angle of choke can result in a lifting capacity as low as 40% of the single leg. WebAll multi-leg chain slings exert a horizontal component of force, which increases as the angle from the vertical becomes greater. No chain sling should be used if the angle …
