132HC Mast Section The main phenomenon of the weakening of the steel wire rope of the tower crane
With the increase of the use of tower crane, the elasticity of the steel wire rope of tower crane will decrease obviously, and it is unsafe to continue using. A decrease in the elasticity of a wire rope is usually accompanied by: 1. Decrease in rope diameter; 2. Extension of pitch of wire rope; 3. As the parts are pressed against each other, there is a lack of space between the wires and the strands; 4. There was a fine brown powder in the recess of the Rope Strand. Although no wire breakage was found, the wire rope was significantly less flexible and reduced in diameter than simply due to wire wear. This situation will lead to the dynamic load under the role of sudden fracture, it should be scrapped immediately.
