Crane Standard AS1418.1 Test Load Combination No. 10

(OP)
Hi, could someone please help me out with understanding the test load combination set out in AS1418.1-2002.

This is combination No.10 in table 4.8 on page 34.

I would have thought that you would add the mass of the crane structure (dead load) and the mass being lifted (hoisted load). Then apply a factor for inertia (phi-4) and another factor for testing (phi-5). This resulting load would be the test load you would apply during commissioning to prove that your crane is strong enough.

For the test combination (column 10) the hoisted load is omitted (line no. 2). I would be grateful if someone can shed some light on this possible anomaly.

King Regards,

The #10 load combination includes a "test load", this test load is the hoisted load with an additional dynamic load factor.

If you refer to clause 4.7.3 it notes that phi_5 is = a function of phi_2, my understanding is that the design test load should be equal to the rated lifting capacity, factored up by phi_5.

I agree with you its not really clearly explained, but the above has always been my take on it.
