Daquan of wire rope specifications and models - what are the parameters of wire rope specifications and models? [summarized]

Daquan specification and model of steel wire rope - Specification and model parameters of steel wire rope. Specifications of stranded wires and steel wires for wires and cables: the above specifications are mainly used by wire and cable companies to manufacture small-sized cables, and some large-sized cables and optical cable companies will use specifications of 1*7-2.4mm1*7-2.7mm1*7-3.0mm1*7-3.96mm1*7-4.8mm or greater. These specifications are mainly used in large-scale communication projects. Of course, some optical cables use optical cable steel wires, such as 0.45mm0.7mm0.8mm0.9mm1.0mm1.2mm1.4mm1.6mm, etc. Among them, 0.45mm and 1.0mm are the most used. It is generally phosphated steel wire, and there are requirements for phosphating layer. In addition to phosphating steel wire, the steel wire for optical cable also has galvanized steel wire for special requirements. Galvanized steel wire is divided into hot-dip galvanized steel wire and electro galvanized steel wire. Galvanizing has requirements on the content of zinc layer (specific galvanizing standard parameters are queried in 20118-2006 standard)

Specification of steel wire rope for imported automobile crane 8*29fi+iwrc:10mm, 11mm, 12mm, 13mm, 14mm, 16mm, 18mm The steel wire rope specifications of imported automobile crane also include: 8*19w+iwrc, 8*19s+iwrc, 8*36sw+iwrc. The 8-strand steel core wire rope has large contact surface and large breaking force. The reverse twisted steel core and non rotating wire rope have the function of anti rotation and anti torsion. 8-strand steel core wire rope is strongly recommended for the steel wire rope of automobile crane.

Specification and model of steel wire rope

Tower crane wire rope, tower crane wire rope specifications of tower crane / tower crane wire rope: 12mm, 13mm, 14m, model 18*7,35w*7, wire contact wire rope specifications: 6*29fi-12.5mm, 13mm, 14mm. The earliest specifications and models of tower crane wire rope and tower crane wire rope are 6*19,6*37, and the diameters are generally 11mm, 12.5mm and 13mm. However, this old structure belongs to ordinary point contact steel wire rope. Due to the backward manufacturing process of steel wire rope in the past, only this steel wire rope specification can be made. However, the durability of this tower crane steel wire rope is not very high and the breaking force is small. In recent years, due to the development of wire contact wire rope and multi-layer strand non rotating wire rope technology, the specification of wire rope presents a good development trend. Then, the specification of tower crane wire rope has changed from unscientific in the past to scientific and durable now. Then there is another question. Is it better to use 6*19fi steel wire rope on the tower crane or 18*7,35w*7 non rotating steel wire rope? If you understand the principle of wire rope stress, use the non rotating wire rope specification. If you don't understand the principle of wire rope stress, use the 6*29fi wire rope specification. If it is considered that the workers do not pay much attention to the use method of steel wire rope in the use process, in fact, 6*19s can be considered. We think it is more cost-effective.

The latest standard specification and model of electric basket wire rope: 4*31sw-8.3m. The national standard electric basket wire rope specifications mainly include 4*19s-8.3mm, 8.6, 4*25fi-8.3mm, 8.6, 4*31sw-8.3mm, 8.6, 4*36sw-8.3mm, 8.6. The development of basket wire rope specifications and models is developed with the development of basket equipment in the construction industry. The previous hanging baskets were all manual. We call them hand block hoist wire rope hanging baskets. The specifications of the hanging baskets are 1.5 tons, 3 tons and 1.6 tons. The 1.5T hand block hoist and 3T hand block hoist basket were all insured and were eliminated in 2004. The specification of steel wire rope for this kind of basket: 4*19-9.3mm for 1.5T and 4*19-13mm for 3T. Later, the specification of steel wire rope for 1.6T basket is relatively reasonable. The specification of steel wire rope for basket is 4*19s-12.5mm. This is reasonable. He used double insurance. Then the electric hanging basket in the back is used.

There are two kinds of hanging basket ropes for Shanghai Regal steel wire rope. One is fully hot-dip galvanized, which is completely produced in accordance with national standards. There is also a kind of wire rope that dealers like to sell. The outer strand is hot-dip galvanized and the inner strand is electro galvanized. The cost is relatively low.

Specification, model and parameters of steel wire rope

Specification of steel wire rope for excavator drill and rotary excavator: 35w*7k-28mm, 30mm, 32mm. Specification of steel wire rope for pile driver: 6k*36sw+7*7, 6k*31sw+7*7 After years of development of specifications and models of rotary excavator wire rope, it started from 6*19,6*37, and then developed from 6*19s, 6*19w to 6*36sw. The breakthrough 6k*36sw, from line contact to surface contact wire rope, and from rotary excavator wire rope to surface contact, has greatly improved the service life of wire rope. However, I think it is 35w*7k to really solve the problem of using the wire rope of the rotary excavator. The specifications of the wire rope of this rotary excavator are characterized by large contact surface with the pulley, large cross section, large comprehensive breaking force, tight interior and high internal wear resistance. It has a 35w*7k-30mm used by a customer, and its durability exceeds imagination. A 280 rotary excavator of CSR Beijing drilled a hole of 5000 meters.

Car crane wire rope, commonly known as crane wire rope, the main car crane wire rope specifications: 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm. Main models: 6*19, 6*37, 6*19s, 6*25fi, 6*29fi, 18*7, 35w*7, 4V, 6V. The specification of steel wire rope for automobile crane has also developed from point contact at the beginning: 6*19,6*37 to line contact specification: 6*19s, filling type: 6*25fi, 6*29fi, non rotating specification: 18*7,35w*7, and triangular strand specification: 4V, 6V.

Specification of crane wire rope, crane wire rope and electric hoist wire rope: 7.7mm11mm13mm15mm17.5mm; 19.5mm21.5mm。 The specification of steel wire rope mainly includes 1 ton, 2 tons, 3 tons, 5 tons, 10 tons and 20 tons of electric hoist. This steel wire rope structure is mainly 6*19 and 6*37.

Specification of hot-dip galvanized steel wire rope: 1mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 11mm, 12mm. Due to the increasing demand for hot-dip galvanized steel wire rope. Moreover, the manufacturing process of hot-dip galvanized steel wire rope is different from that of electro galvanized steel wire rope. Most of our Shanghai Junwei steel wire rope factory do electro galvanized steel wire rope in stock. This is caused by the market. Dealers sell electro galvanizing, because the price of electro galvanizing is 1000 yuan a ton cheaper than that of hot galvanizing. The market competitiveness is relatively strong, but users do not know the principle of electroplating and hot plating. I don't know that the cost performance of electroplating is far inferior to that of hot-dip galvanized steel wire rope. At present, few users will choose hot-dip galvanized steel wire rope, mainly because they do not understand it. Customers who need hot-dip galvanized steel wire rope are also worried. Many can basically complete orders with customized processing. However, many users and dealers are basically small in number, and then they need cash. As the first steel wire rope manufacturer to make hot-dip galvanized steel wire rope in stock.
