Rotate the hook after treatment

      When rotating hook after hook wire rope kink,hoist equipment this time can no longer be landing hook, otherwise it is possible to make them a rope damaged by excessive force, may take the following approach:
       (A) in the weight lifting off the ground is not high and the machine performance permitting, you can use luffing way to put weight down, then put positive spin hook.
       (2) If the weight has been lifted high off the ground, you can only think of ways to close the surrounding buildings,load chain or other person crane hanging cage to spin positive hook.
       (3) In case of hook rotation, torque should release the rope, the specific method is: the hook into the ground wire to unlock the fixed end, in accordance with the hook rotation number m times the rope match n is the number of base k (as the case may increase or decrease), according to the wire rope strands twisted inverse direction,manual hoist turn the end of the rope release torque, then loaded on a fixed end. Will play a maximum elevation boom, hook ups and downs repeated several times to check the results, you can repeat the above steps until the hook stability.
