The invention relates to a superlift tensioning mechanism of a crane and a control method. The superlift tensioning mechanism comprises a superlift winch, a winch angle detecting component, a winch locking component, a tensioning component and a control component, wherein the superlift winch is arranged above a suspension arm through a superlift support; a superlift steel wire rope is connected among the superlift winch, an arm head of the suspension arm and the tensioning component; and the control component can control rotation of the superlift winch so as to tighten the superlift steel wire rope. When the winch angle detecting component detects that the superlift winch reaches a preset winch angle, the superlift winch is locked through the winch locking component, and the tensioning force of the superlift steel wire rope is adjusted through the tensioning component. According to an embodiment of the invention, the control precision of superlift tensioning can be improved.
