What does a utility crane mean?

"A crane without a body" comes from Song Taizong's "knowledge of fate" and is an image in the poem.

Original text:

The mountain of Fuyang is called Ritong, and the six laws are in tune. Seven chords are all meanings, and the detailed examination is also empty. Quiet autumn, listening makes me think deeply. The rhyme in the orchid, the eternal winter night, blends with the hearts of the ancients on the avenue. Only by controlling the south wind for a lifetime can we know that we are broad-minded At the beginning of the play, the sound disappeared, and Henty and Qiu Si turned to each other. Why is it sad to say goodbye to cranes? I can't smell the intermittent waving. Slow rain, cold spring and wonderful fragrance.

Translation:

The mountain in the south of the peak is called the sun phoenix tree, and the six methods follow the music. Seven chords all mean something, and reviewing is just like being empty. In the quiet autumn, I will meditate on the orders I obey. The rhyme in the orchid, eternal in winter night, conforms to the ancient thought. Only when Shun controlled the south wind to govern the people did he know that Yao was educated and wise. At the beginning of the play, the moving voice left, and Tai Tai and Qiu Si turned alternately. How sad is the Utibei River? I just heard that I was busy waving intermittently. Slow pulling urges rain and wind, and cold springs are wonderful.
