1000 kg load<br />

This shows the effect of increasing the included angle in slings.You<br />

will see that, with an included angle of 170°, the load on each sling<br />

is six times the actual weight being lifted.<br />

Do NOT exceed the 120° included angle which provides each sling<br />

with the same weight as the actual load.
