Tradução de "Crimping it on impact..."

Alguém poderia traduzir para mim esse trecho do livro: "Strange the dreamer". Eu fiquei em dúvidas quanto ao significado do verbo "crimping" e e outras coisas mais.

"On the second sabbat of Twelfthmoon, in the city of Weep, a girl fell from the sky.
Her Skin was blue, her blood was red.
She broke over an iron gate, crimping it on impact, and thre she hung, impossibly arched, graceful as a temple dancer swooning on a lover's arm".
