Clamp is a kind of connecting device for connecting pipe fittings, valves and pipe fittings with grooves. It is used to tighten the coupling between quick connectors. Generally, the two connectors are equipped with gaskets, rubber, silica gel and tetrafluoroethylene. The utility model has the advantages of good performance, high sealing degree and simple installation. The steel wire clamp is a hoop made of two steel wires. The clamp has the characteristics of beautiful appearance, convenient use, strong tightening force and good sealing performance. It is mainly used for connection, fastening and sealing of common full rubber hose, nylon plastic hose, cloth hose, hose and other interfaces of vehicles, ships, diesel engines, gasoline engines, machine tools, fire protection, and other mechanical equipment and chemical equipment.

Eyebolt is also a common small part in fasteners. Its eyebolt is forged by warm quenching. The external thread length is "H", and the bolt is fixed with other parts. Bolts of the same quality grade must be selected for replacement. Use process of eyebolt:The lifting ring screws are integrally forged, normalized and oxide skin removed; Forgings shall be free from over burning and crack defects; The ring screws are subject to hardness test, and the hardness value is hrb67-95. The lifting eye screw is used for vertical installation on the plane of the workpiece. Its joint surface is very flat and the joint is very tight

Eye nut refers to the part that the nut and bolt or screw are screwed together for fastening. It is a kind of original part that must be used for all production and manufacturing machinery. The eye nut is a hanging piece commonly used for fixing in engineering. There is a screw thread under the nut, which can be drilled and fixed with the screw mouth according to its different specifications. The eye nut is a part that closely connects the mechanical equipment. It can only be connected together through the inner thread, eye nuts and screws of the same specification. The lifting eye nut is often used in conjunction with the external thread column to lift various equipment, such as molds, chassis, motors, etc. This standard specifies the ring nut with m8-m100*6 thread specification. This standard is applicable to general loading and unloading of hoisting machinery and appliances.    

The turnbuckle is used to tighten the steel wire rope and adjust the tightness. OO type is used for infrequent disassembly, CC type is used for frequent disassembly, and CO type is used for frequent disassembly at one end and infrequent disassembly at the other end. According to different forming methods, turnbuckles are mainly divided into cast Maanshan Steel, ordinary carbon steel and forged. At present, there are mainly two kinds of ordinary carbon steel and forged. Ordinary carbon steel orchid screws are mainly used for static binding and stable scenes in unimportant occasions, such as garden windproof, agricultural shed, etc. Forged orchid screws are used for lifting and freight binding reinforcement. Such as goods binding, sling connection, steel structure cable rod connection, etc.

Shackle is one kind of rigging. The usual shackles in the domestic market are divided into three categories: national standard, American Standard and Japanese standard; American standard is the most commonly used one, which is widely used because of its small size and large bearing weight. Compared with our national standard shackles and Japanese shackles, American Standard shackles have smaller volume, lighter weight and higher safety factor.American Crosby shackles and cross pins are made of 40Cr, but most of our domestic American Standard shackles are forged with 45 steel, and the cross pins are made of 40cr Table treatment.Generally, they are galvanized or painted.

The lifting chain is an essential and important lifting device of the crane. The length of the chain can be adjusted according to the lifting height of the crane. It plays an important role in improving the operating efficiency of the crane and expanding the operating range of the crane. The allowable wear value of the lifting chain shall not exceed 10% of the bar diameter of the ring chain or the thickness of the auxiliary tools. From the plane where the main ring is not bent, the main ring shall be scrapped if it is twisted more than 10 degrees. It is forbidden to use the lifting chain if cracks, bending or twisting occur at any part of the lifting chain and there are stuck or stiff resistance between the ring hinges, which cannot be eliminated. The sexual elongation of the lifting chain and the single ring shall not exceed 5% of the original length. The lifting chain includes short ring chain, lifting chain, etc. Use 8 grade ordinary precision chain, welded lifting chain, non-standard lifting circular chain, and high-strength circular chain. The lifting chain is divided into M4, P5, S6, T8 and V10 series according to the mechanical properties of the finished chain. The grades are G30, G50, g80, G100, etc., and the materials are mainly carbon steel and stainless steel. Grade g80 and G100 lifting chains are made of high-quality synthetic steel (manganese steel, etc.) and applied to: strength correction chain, non correction chain, binding chain and hoist special chain; The surface is treated with natural color, polishing, blackening, painting, hot dipping and galvanizing, and the safety factor is 4 times, 5 times, 6 times and 2.5 times of the experimental load.    

The steel wire rope is a spiral steel wire bundle that twists the steel wires that meet the requirements of mechanical properties and geometric dimensions together according to certain rules. The steel wire rope is composed of steel wire, rope core and grease. Steel wire rope is a kind of rope that is twisted into strands by multi-layer steel wires, and then twisted into a spiral shape by a certain number of strands with the rope core as the center. In material handling machinery, it is used for lifting, traction, tension and bearing. The steel wire rope has high strength, light weight, stable operation, not easy to break suddenly, and reliable operation. The steel wire rope needs to bear the alternating load during its use, and its service performance is mainly determined by the mechanical properties of the steel wire, the surface state of the steel wire and the structure of the steel wire rope. The steel wire material includes carbon steel or alloy steel, which is made by cold drawing or cold rolling. The cross section of the steel wire is round or shaped (T-shaped, S-shaped, Z-shaped). The steel wire with shaped cross section is mainly used for the production of sealed steel wire rope, which has high tensile strength and toughness. The steel wire is properly surface treated to meet the needs of different service environment conditions.                           

The wire rope clip is mainly used for temporary connection of the steel wire rope, fixation of the rear hand rope when the steel wire rope is wound through the pulley group, and fixation of the cable wind rope head on the derrick. The casting process is commonly used in the market. However, due to some defects of natural process (air hole, crack, sand inclusion), the  clamp should be used cautiously in special occasions such as humidity, acidity, alkalinity, impact frequency, etc. A forged steel wire rope clamp has been developed. Purpose of wire rope clip:1、Casting clamps are commonly used for static bolting and rope pull wire fastening, such as power, communication lines, binding and fastening, etc.Forged steel wire rope clamps are often used for lifting and bearing, such as various engineering hoisting machinery, metallurgical and mining equipment, port and railway loading and unloading, forestry machinery, power equipment, aviation and offshore, hoisting and traction rigging.Stainless steel clips are used in marine fittings, chemical plants, radiation and other environments because of their corrosion resistance and not easy to rust.2、 Features: with the same strength as steel wire rope, it is safe to use, beautiful in appearance and smooth in transition. The safety load of hoisting operation is large, it can resist impact load and has a long service life. Precautions for use of steel wire rope clamp: it shall not be used for a long time. It shall be inspected and scrapped regularly. It shall not be used repeatedly.
