# Thread: 4 eyes of the gantry crane from which to suspend a basket

1. ## 4 eyes of the gantry crane from which to suspend a basket

Hello everybody!

4 eyes of the gantry crane from which to suspend a basket are to be subjected to a static load test.

I will explain everything from beginning to end to the best of my knowledge. I am not much of an expert on ships myself. The ship in question is equipped with a gantry crane which, in turn, is used for lifting hatch covers. 4 eyes of the gantry crane are to undergo a static load test but this time a basket will not be suspended / hung from the 4 eyes of the gantry crane.

I have come up with such a sentence:

4 eyes of the gantry crane from which to suspend a basket are to be subjected to a static load test.

What do you think of the sentence?

Thank you.

Please pay special attention to the bolded fragment.

The gantry crane's four lifting points, from which no baskets are suspended this time, will be subjected to a static load test.

I am not much of an expert on ships either, but I'm fairly certain that the words "from which to suspend a basket" are merely descriptive. The OP states that a basket can be attached and that the crane is used to lift hatches.

The test is to see how much weight can be lifted at the attachment points before the lifting mechanism fails. Among the component loads tested would be: torque on the drum shaft, cable attachment to the drum, cable tensile strength, and cable eye integrity.

Assuming the test is for the lifting mechanism plus whatever cables, chains, links, etc. actually connect with a load. I suggest:

'A static load test is to be conducted at the gantry crane's four lifting points.'

What is not clear (but inferred) from the OP is that all four lifting points are engaged at the same time in each lift. If so, then a single test engaging all four at the same time would identify a weak link. If not, then separate tests should be specified for each lifting point.
