What are the usage specifications of steel wire rope?

1. Overloading is strictly prohibited. It is strictly forbidden to operate with power other than manpower. Before use, make sure that the machine parts are intact, the transmission parts and lifting chains are well lubricated, and the idling condition is normal. Check whether the upper and lower hooks are fastened before lifting. It is strictly prohibited to hang heavy objects and other wrong operations.

2. The lifting chain of explosion-proof chain block shall be hung vertically without twisted links, and the lower hook frame of double chain shall not be overturned. The operator should stand in the same plane with the bracelet wheel and pull the hand chain, so that the bracelet wheel rotates clockwise, so that the weight can be raised; Pull the hand chain in the opposite direction, and it will slowly fall at noon. When lifting heavy objects, it is strictly forbidden for personnel to do any work or walk under the heavy objects to avoid personal accidents.

3. During the lifting process of explosion-proof chain block, no matter the weight rises or falls, when pulling the bracelet, the force should be even and gentle. Do not use excessive force to avoid the hand chain jumping or snap ring. If the operator finds that the hand tension is greater than the normal tension, he should immediately stop using it. Maintenance method: after use, the hoist should be cleaned and coated with anti rust grease, and stored in a dry place.

4. After cleaning and maintenance, the chain slings should be subject to no-load test to confirm that they work normally and the braking is reliable before they can be delivered for use. The friction surface of the brake must be kept clean.

Before buying the chain electric hoist, you can distinguish the quality of the chain electric hoist according to the following points. First, after the power is turned on, control the chain electric hoist to move up, down, left and right, observe whether the direction key is correct, and pay attention to whether there is a brake sound when the up and down operation stops. In addition, check whether the chain slides after the stop. If so, Shanxi Taiyuan Steel Wire Rope Daquan indicates that the friction plate is too loose or the installation is abnormal.

① This method stipulates that the steel wire rope connecting device (commonly known as hook head) equipped with a thimble is manually spliced with six strand steel wire ropes with alternating twist fiber rope core or steel wire rope core.

② It is made into a plug-in joint after five times of insertion, which can be composed of three times of whole strand insertion and two times of reduced strand insertion. All plug-in joints should be opposite to the twisting direction of the steel wire rope; Except for group interleaving, the tail ends of all strands interleaved in other groups shall be opposite to the twist direction of the steel wire rope.

③ The interleaving shall be carried out in a cross way of one up and one down.

④ If the steel wire rope has a fiber main core, the rope core should be completely threaded through the tail ends of the group, and then the exposed rope core should be cut off. If the strand has a fiber core, the strand core should remain in the original strand.

⑤ If the steel wire rope has an independent metal wire rope core, the rope core shall be divided into three parts. They are: － two shares, － two shares, － two shares plus their cores. The three parts shall be spliced with three staggered tails, and only through the three complete connectors.

⑥ If the steel wire rope has an independent metal wire strand core, the core should be folded inward during group insertion and completely inserted into the center of the insertion head for five complete penetrations.

⑦ All insertion shall be firmly tightened until it is consistent with the center line of the inserted steel wire rope. In order to make the inserted parts smooth and round, appropriate tools should be used for shaping to make them enter the appropriate position.

⑧ The ferrule used should match the diameter of the steel wire rope, and the ferrule clip should be firm.

⑨ Burrs will inevitably appear at the connector. In order to avoid operators scratching their hands, epoxy resin and other materials should be used together with special soft plastic cylindrical tools (such as mineral water bottles) to pour and seal the connector after the connector is completed. Specific steps: fix the soft plastic cylindrical tool at the socket with rope or iron wire, erect the steel wire rope, close the lower mouth of the cylindrical tool to prevent the liquid from flowing out, and then pour the epoxy resin liquid into the cylindrical tool. Note: during pouring, the liquid should be lower than the upper plane of the tool. After pouring, it should be placed vertically for more than 24 hours to solidify the epoxy resin.
