Use and Maintenance of wire ropes
As an important component of engineering machinery products, steel wire ropes directly determine whether the machine can continue to produce, and the cost is high, but it is also a wearing part. Therefore, how to extend the service life of steel wire ropes is very important.
When transporting, loading and unloading the wire rope, the wire rope coil should be placed on the pallet or the steel pipe should be inserted into the shaft hole and then inserted with a forklift for transportation. It is strictly forbidden to use a forklift to directly shovel the surface of the wire rope. It is strictly forbidden to roll the wire rope drum directly from a high place such as a car to avoid shoveling damage to the surface of the wire rope and random winding of the wire rope.
Before installing the wire rope, its type, structure, diameter, strength level, and surface quality must be checked. It can be used only after it meets the requirements. When unwinding the wire rope, place the rope drum on a special rack to avoid kinking of the wire rope. The winding direction of the wire rope on the drum must be based on the twist direction of the wire rope. Right-twisted ropes are arranged from left to right, and left-twisted ropes are arranged from right to left. After the installation is completed, use 10% of the rated load to run the wire rope several times to make the wire rope more firmly attached to the drum.
Maintenance of wire ropes during use is very important. Doing this well will not only extend the service life, but also improve work efficiency and prevent accidents. Maintenance during use mainly refers to the lubrication and anti-rust oiling of the wire rope.
The steel wire rope has been coated with enough grease during manufacture, but after operation, the grease will gradually reduce, and dust, debris and other dirt will stick to the surface of the wire rope, so it should be cleaned and refueled regularly. In order to prevent the wear of the wire rope and sheave and the rust of the wire rope, the simple method is to use a wire brush and other corresponding tools to wipe off the dust and other dirt on the surface of the wire rope, and evenly apply the heated melted grease on the surface of the wire rope.
Because steel wire ropes not only bear load, fatigue, and wear, but also work in harsh environments,
routine maintenance and inspection are very important during use.
The main contents of maintenance and inspection are as follows:
1) Regularly re-coat the wire rope with grease that has anti-rust and lubrication effects.
2) Regularly remove grease and dust and other impurities on the surface of the wire rope.
3) Routinely inspect and record the wear,
Broken wires, rust, grease, deformation, diameter and other abnormalities of the wire rope.
4) The wire rope should be inspected before use. When the wear, broken wires, broken strands,
corrosion, stretching, bending, deformation, fatigue, diameter, degree of rope core exposure, etc.
Of the wire rope reach the replacement standards specified in the relevant regulations,
replace the rope with a new one in a timely manner.
1) When there is rust or dirt on the wire rope, it must be cleaned and oiled in time;
2) Apply oil once every 4 months;
3) Wire ropes must not be stacked to prevent sprains;
4) During the use of the steel wire rope, if there are oil dripping out of the surface,
It means that the steel wire rope has been subjected to considerable force. At this time,
You should stop increasing the load and inspect it. If necessary, replace the steel wire rope with a new one.
Scrap standards for Wire ropesE
1. When 7-8 broken wires are broken within one pitch of the wire rope, it should be scrapped. If the entire sub-rope is broken or the rope core is extruded, causing structural damage, the wire rope should be scrapped.
2. The wire rope is worn and the diameter is reduced. If it exceeds 40% of the diameter of the wire rope, it should be scrapped.
3. Steel wire ropes that have been overloaded must not be used again. When the appearance of the wire rope is seriously deformed, the structure is damaged, the rope core is extruded or there is obvious shrinkage, and the accumulation phenomenon should be scrapped.
The above is the use and maintenance method of wire rope. Rongxing rope strictly controls every link of steel wire rope production, and has high standards and strict requirements for each component to ensure that each steel wire rope delivered by the factory is of high quality and high performance.
