Installation for Angular Loading

Angular Loading.gif (5911 bytes)

The threaded shank must protrude through the load sufficiently to allow full engagement of the nut.
Thickness of spacers must exceed this distance between the bottom of the load and the last thread of the eye bolt.
If the eye bolt protrudes so far through the load that the nut cannot be tightened securely against the load, use properly sized washers to take up the excess space BETWEEN THE NUT AND THE LOAD.
Place washers or spacers between nut and load so that when the nut is tightened securely, the shoulder is secured flush against the load surface

Direction of Pull Adjusted Working Load
45 degrees 30% of rated working load
90 degrees 25% of rated working load


In accordance with good rigging and maintenance practices
All rigging equipment and hardware should be inspected periodically
