Use And Maintenance of Wire Rope for Rotary Drilling Rigs

------------------------- 1 -------------------------

Wire rope uncoiling as well as installation, the correct method should be used to prevent wire rope kinking. Also pay attention not to make the surface of the wire rope stained with sand, so as not to exacerbate the wear and tear, affecting the service life of the wire rope.

------------------------- 2 -------------------------

If it is necessary to cut off the whole coil of wire rope when it is used, the end should be tied or fused to the wire rope.

------------------------- 3 -------------------------

The wire rope should be arranged neatly when winding on the reel, and should not be wound randomly, otherwise it will cause the wire rope to produce serious extrusion bite and pressure injury during the work, which will affect the service life of the wire rope.

------------------------- 4 -------------------------

New ropes must be “broken in” under light loads at the beginning of their use. This can improve the service life of the wire rope. Use should also avoid excessive impact load on the wire rope damage.

------------------------- 5 -------------------------

Special attention should be paid to accurately calculating the distance in the process of drilling down, and the rope should not be over-released to prevent the rope from intertwining in the state of slackness and leading to structural damages, which will make the whole wire rope obsolete.

------------------------- 6 -------------------------

After the wire rope is put into use, the performance will be gradually reduced. Therefore, the new rope should be used for a period of time should often check the parts of the wire rope prone to damage, such as the wire rope occurs “biting rope” parts, the lower layer of the drum wire rope, the occurrence of violent impacts through the pulley at the wire rope and in and out of the drum parts of the wire rope, etc., through the frequent inspection for reasonable and safe use of wire rope to provide a basis.

------------------------- 7 -------------------------

Broken wire treatment: When the wire rope appears broken wire still need to be used, the broken wire should be handled in time. You can use steel wire pliers to clamp the head of the broken wire, before and after repeated bending until the wire breaks. After this treatment, the broken wire head will be clamped between the strands, will not cause harm to the use of wire rope. When the number of broken wires in a twisting distance reaches 10% of the total number of outer layer wires, the wire rope must be replaced.

------------------------- 8 -------------------------

Suggestion: Since the wire rope of rotary drilling rig belongs to single-rope lifting, i.e. there is a free rotating end of the wire rope in the work, based on the consideration of safety and operation convenience, the anti-rotation wire rope should be preferred when purchasing the wire rope.
