How to wind the steel wire rope corectly?
Here is an example showing how important it is to wind the steel wire rope correctly:
A crane will lift concrete member in a construction site, while methods for steel wire rope winding on the pulley are wrong, and the lifting worker is unwilling to re-wind the steel wire rope, he thought it will be ok because before he lifted even heavier objects perfectly, he commands to lift objects, but steel wire rope at one side breaks to cause one worker injury as the concrete member is not lifted completely. So it is very important to wind the steel wire rope correctly.
