What specification of crawler crane wire rope? Does the crawler crane have a special steel wire rope? Crawler crane wire rope is the reason for frequent crane operation accidents. Therefore, it can be seen that the purchase of crawler crane wire rope needs to know what specification to use or whether there is a special wire rope. Today, Xiaobian will solve this problem for you. Crawler crane wire rope can be customized by the manufacturer according to the specific situation, which will certainly solve this problem.

Then Xiaobian will give you a popular science on how to check the steel wire rope of crawler crane, so as to prevent and control the future.
1. How to check the steel wire rope of crane crawler crane? First of all, we should understand the inspection cycle of the crawler crane wire rope. The crawler crane wire rope of the lifting mechanism should be inspected at least once a week, and the other crawler crane wire ropes in operation should be inspected at least once a month. We should carefully fill in the crawler crane wire rope situation report, mark the date and sign, and put it into the equipment file for future reference.
2. When all crawler crane wire ropes are idle for one month or more due to the suspension or storage of small cranes, a thorough inspection shall be stopped before reuse.
3. It is not suitable to use multi strand crawler rope hoisting mechanism. Installation or measures shall be taken to avoid twisting of crawler crane wire rope during operation. It is not allowed to use the braided and extended crawler crane wire rope.
4. The steel wire rope of crawler crane shall be arranged uniformly on the drum, without slot hopping and disorderly rolling, and the tail end shall be fixed reliably. When the hook is at the lowest position, there shall be no less than two safety rings on the drum.
5. When the rope clamp is used for connection, the requirements in the following table shall be met, and the connection strength shall not be less than 85% of the breaking force of the steel wire rope of the crawler crane. The spacing between rope clamps shall not be less than 6 times of the diameter of the steel wire rope of the crawler crane. The rope clamp pressing plate shall be placed on the long side of the steel wire rope of the crawler crane, and the steel wire rope of the crawler crane shall be biased by one third to prevent the positive and negative interleaving device. The extension of the short side of the crawler crane wire rope shall not be less than 150 mm, and it shall be wound and fixed with fine lead wire.
6. In order to ensure safety, when the number of broken inner and outer wires of the crawler crane wire rope reaches a certain proportion of the number of wires, the crawler crane wire rope shall be scrapped. The scrapping specification of crawler crane wire rope is: when the number of broken wires of cross wound crawler crane wire rope reaches 10% of the total number of wires, the crawler crane wire rope shall be scrapped. During calculation, each thick steel wire shall be calculated as 1.7. When one strand is broken, it shall be scrapped. When the diameter of the outer steel wire is worn by 40% or the rope diameter is reduced by 15%, it shall be scrapped.
What specification of steel wire rope for crawler crane? Does the crawler crane have a special steel wire rope? The above is the article compiled by Xiaobian for you. I hope it will be helpful to you. If you want to buy wire rope, you can contact Shenhu wire rope manufacturer to solve all your problems efficiently.
