Wire rope inspection steps and matters needing attention:

1. Overview:

(1) the types of wire rope:

Points in the form of the structure can be divided into smooth round, ribbed and twist silk three; Is divided into reuse and according to the use with two kinds of transmission; According to the manufacturing process can be divided into the twist system (cold drawn) and winding two; According to the surface shape can be divided into planar, triangular and three.

(2) testing purpose:

Through the study of the appearance quality inspection of steel strand, judge whether the qualified and determine its specifications.

2. The inspection items:

The appearance quality of the (1) :

Check of rustily, defects such as broken wire.

(2) mechanical properties:

According to the requirement to choose the appropriate mechanical test items or according to the requirements of the product's technical conditions for the corresponding test program test.

3. Test method:

1) the appearance quality visual method.

2) mechanical properties test.

1 tensile experiment:

Tensile samples should be in tension or the pressure, to determine the tensile strength of specimen.

2 impact experiment:

Pendulum impact device should be adopted.

3 bending fatigue test:

Under prescribed conditions for determination of specimens under the action of repeated bending load on the stress.
