What are the correct ways to check wire ropes?
1. Inspection method
For wire rope inspection, use oil calipers to measure the diameter. The measurement method is the outer diameter of the two strands of the wire rope. There should be a measuring point every 100m in the middle, and two measuring points are measured at the front and back 1m respectively. For comparison, the measurement points are replaced every month, so that the monthly fixed, comparative analysis.
The measured value of the lay length in the wire rope strand is compared with the lay length measured at the factory of the new wire rope to determine the degree of loose twist.
2. Safety inspection parts
In general part inspection, attention should be paid to check the movement of the wire rope and the fixed beginning and end; attention should be paid to the weaving of the wire rope passing through the pulley block or bypassing the pulley block, especially any part of the wire rope that bypasses the pulley under load: attention should be paid to checking the rope section of the balance pulley; Pay attention to checking the rope section that may cause wear in a certain part of the machine; pay attention to checking the rope section with rusted, corroded and fatigued parts.
Inspection of the rope end The safety and reliability of the fixed connection part of the rope end is very important to the safety of the hoisting machinery. The following safety inspections should be carried out on the rope end; the wire rope drawn from the fixed end should be inspected, because fatigue occurs in this part Broken wires or corrosion are extremely dangerous; the deformation or wear of the fixture itself should also be checked; the rope end fixtures that use pressed or forged rope screens should be checked for cracks, and whether the rope screen and the wire rope are connected. There is a possibility of slippage; check the broken wire and corrosion inside the rope end of the detachable pole-shaped joint, rope clamp, pressure plate and other devices and the rope end to ensure that the rope end is the same as the curtain.
3. Safety inspection cycle
daily observation. It is the crane operator's responsibility to observe any visible part of the wire rope as much as possible during each working day, so as to detect the damage of the wire rope in time.
Damage and deformation, if there is any abnormality, it should be reported to the competent department for processing.
Regular safety inspection by supervisors: For general hoisting machinery and wire ropes used for hoisting and binding operations, safety inspections shall be carried out at least once a month.
Supervisors shall conduct safety inspections at least once a week for the wire ropes used for lifting machinery on construction sites.
Supervisors shall conduct safety inspections at least twice a week for the wire ropes used for lifting machinery for hoisting molten or hot metals, acid solutions, explosives, inflammables and toxic items.
Being able to do the above can not only prolong the service life of the wire rope, but also eliminate the potential safety hazards caused by the wire rope, work safely, and things are small.
