Why do prefabricated components need tower cranes
Patent technology production of phosphating coating steel wire rope, preferred department or zinc manganese phosphating, compared with smooth steel wire rope production process, only increased the final wear-resisting phosphating process, the wire rope greatly improve wear resistance and corrosion resistance, using phosphating steel twist wire rope directly. The fatigue test data show that the phosphating coating is smooth with structure wire rope fatigue life of wire rope around 3-4 times (lab) under the condition of comparable with the study of wear resistant phosphating formula, there is the possibility of significantly increase.

Cement bricks, are generally large components, especially the use of more Bridges, also includes building use, these artifacts size large weight is heavy, super high width is frequent, handling transport these artifacts must use crane, tower crane can meet the needs of the lifting transport goods. Common varieties of wire rope for crane are phosphating coating, galvanized steel wire rope, stainless steel wire rope, wire rope used in atmospheric environment, patent technology production of manganese phosphate coating the longest service life of wire rope, heavy corrosion environment optimizing hot galvanizing - phosphate double coating wire rope.
