A clamping mechanism 100 has a limiting sleeve 1 fixed below an end part of a lifting arm of a crane which gradually tapers from top to bottom away from an axis of the limiting sleeve. A lifting rope 3, possibly an aluminium rope, of the crane can hoist an aluminium wire reel into the limiting sleeve and be abutted against an inner wall of the limiting sleeve. The clamping mechanism may have a guide disk 2 fixed to the inside of the sleeve, the guide disk having a through hole to allowing the lifting rope to pass through. The clamping mechanism may have limiting plates arranged circumferentially around the lifting rope with each plate having first and second plates 11, 13 connected by an elastic member 12, such as a spring.
