Types of lead sealing pliers and casting requirements
Lead sealing pliers The sealing pliers are assembled from castings. There are three types: large, medium, and small. Various styles of lead sealing pliers can be manufactured. The end is wrapped with a plastic sleeve to avoid slipping caused by electric shock and hand conflict. Sealing pliers are specially used for laser anti-counterfeiting digital seals, general seals, and anti-counterfeiting seals. The lead seal is a device similar to a lock applied by a specific person after the goods are loaded into the container and the door is properly closed.
Lead seals can be divided into customs seals, commodity inspection seals, and commercial seals according to different persons applying them. Once the lead seal is properly locked, it cannot be opened unless it is violently damaged (ie, cut), and the damaged lead seal cannot be used from the beginning. Each lead seal has a unique number identification. As long as the appearance of the container is intact, the container door is properly closed, and the lead seal is properly locked, it can be proved that the container has not been opened privately during transportation and the condition of the container is supervised by the packer during packing.
A variety of pliers are often used in the installation and repair of cranes, which are generally divided into wire cutters, sealing pliers, needle-nose pliers, bolt cutters, and wire strippers. Wire cutters and lead sealing pliers are the most frequently used thing in installation and repair operations. It consists of a pliers head and plier handle. The pliers head includes four parts: jaws, tooth edges, knife edges, and guillotine jaws. Repair personnel should pay attention when using wire cutters to seal the pliers: When using wire cutters to seal the pliers, it is necessary to check whether the insulation of the plier's handles is excellent, otherwise, the live operation is forbidden to avoid electric shock.
When using wire cutters and lead sealing pliers to cut a live wire, it is necessary to do it individually. It is not allowed to cut two or more wires together with a knife to avoid a short circuit between the phase wires or between the phase wire and the neutral wire. When using wire cutters to seal the pliers, the knife-edge should face the operator to facilitate the manipulation of the cutting part. The pliers head cannot be used as a hammer instead of a hammer to avoid deformation. During live operation, keep your hands and the metal part of the wire cutters at a distance of more than 2cm to avoid electric shock. The movable parts of wire cutters and lead-sealed pliers should always be lubricated and smooth to ensure that they open and close sensitively.
