People who have used the tightener are familiar with how to use it. Firstly, loosen the steel wire rope or galvanized iron wire on the tightener and fix it on the cross arm. Use wire clamping pliers to clamp the wire, and then pull the special wrench to fix the steel wire rope. Finally, wrap the steel wire rope or galvanized iron wire on the roller of the ratchet. The principle of a tightener simply lies in the wire clamp. Through the wire clamp, the tightener can fix the steel wire rope on the drum. Therefore, the tightener can greatly improve the safety during the lifting process of cargo transportation and prevent cargo from slipping. There are many types of tighteners, such as tiger head tighteners, curved tooth tighteners, multi-functional tighteners, and so on. The multifunctional wire tightener not only includes the wire clamping part, but also the wire tightening part. Its feature is that its wire tightening part is equipped with a tooth wheel and a reversing hook that meshes with the tooth wheel in addition to a ratchet on the central shaft.

　　Summary: When using, it is necessary to check whether the wire clamp is damaged or not, and to check whether the steel wire rope is fixed on the cross arm and wrapped around the roller of the ratchet, so that the use of the wire tensioner is successful.

　　Application fields of tightener: mechanical equipment for infrastructure construction projects such as metallurgy, mines, slope tunnels, buildings, highways, bridges, and shaft protection.
