Q: What is the difference between cable stayed bridge and suspension bridge?: Cable-stayed bridge, also called cable-stayed bridge, is a bridge that uses many cables to directly pull the bridge on the pylon. It is a structural system composed of a pressure tower, a tensile cable and a bent beam. It can be regarded as a multi span elastically supported continuous beam instead of a pier. The utility model can reduce the bending moment in the beam body, reduce the height of the building, lighten the weight of the structure and save the material.The cable-stayed bridge is composed of pylon, main girder and stay cable.

Q: What are the connections and differences between hooks, slings, rings and heavy truck rings in cranes? What are the hoisting designs?: Chain lifting sling series: high strength chain sling, single leg sling, double leg sling, three leg sling and combination sling.5. traction rope series: synthetic fiber traction belt, wire rope, traction rope, trailer rope, high tension wire, traction rope, silk rope.6. ladder series: nylon rope ladder, rope ladder, ladder, climbing ladder, closed sea rescue ladder.7., metallurgical spreader series: C spreader, bending hook, billet clamp, round bar clamp, metallurgical special sling,

Q: How do you tie the wire rope?: Manganese phosphating belongs to wear, corrosion, phosphating, automobile transmission, steel gear is through the manganese phosphating treatment, can ensure that the car gear for more than ten years without damage. Phosphating coating of steel wire rope China patent technology production, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just add the last bonderizing process, steel wire for rope wear resistance and corrosion resistance is greatly improved, the use of direct phosphating steel wire twisting steel wire rope. The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3-4 times the same structure of domestic smooth steel wire rope, wire rope surface is 2-3 times of imports, (laboratory comparable conditions) with the research on the wear resistance of phosphating, and greatly enhance the possibility, is currently the most advanced technology in the world of steel wire rope field. Manganese phosphating is bonderizing, can solve the problem of wire rope wear during use, smooth wire rope being eliminated, because the phosphating coating steel wire rope in short supply, the more sought after, need to ask a few companies.

Q: The wire rope lock can hang a lot of things: 2. galvanized steel wire rope, including hot-dip galvanizing and electro galvanized two, in general, hot galvanized zinc layer thickness, zinc plated zinc thin3. stainless steel wire rope, 304 or 316 stainless steel based, anti-corrosion effect is very good, but expensive4. carbon coated steel wire rope, wire rope based on polyethylene, polypropylene or nylon outer coating5. smooth wire rope, short service life, sharp decline in market demand, will be phasing out the phosphating coating steel wire rope.

Q: What are the selection principles for lifting cranes?: To avoid the use of large lifting capacity of the crane lifting capacity of small parts, small crane overload lifting component, or choose not modified after the actual loading test of crane hoisting, shift or use the high cost of equipment.

Q: What are the specifications for the length, length, and method of operation of the wire rope?: The use of wire rope in the atmospheric environment, mainly caused by the failure of wire rope is fretting fatigue, at present, the wire rope for the first time in the field of fretting fatigue control measures is the phosphating coating steel wire rope patent technology production, steel wire after manganese phosphating or zinc manganese treatment, wear resistance, enhance the surface of steel wire that is not easy to wear and corrosion resistance of the fatigue life is greatly improved

Q: What is the safety factor of the wire rope as a motor lifting equipment, slings and slings?: 4. coated steel wire rope, the carbon steel wire rope based on the rope or rope coated with polyethylene or polypropylene5. smooth wire rope, in 1834 the British began production in China in 1939 started production in Tianjin No.1 steel wire rope factory, with the phosphating coating steel wire rope into the market size gradually increased, will be fully replace phosphating coating steel wire rope.

Q: Why are the suspension bridges a main cable, even a n multi sling, not a bridge directly from the tower?: The cable-stayed bridge is a cable-stayed beam with a plurality of cable on the tower bridge. It consists of beam, cable and tower is composed of three parts. The cable-stayed bridge is a self anchored system, the level of power cable by Liang Chengshou, in addition to supporting beams on the pier, also supported by the cable leads to the tower. According to the materials used in the beam, they can be divided into steel cable-stayed bridge, composite beam cable-stayed bridge and concrete beam cable-stayed bridge.Cable stayed bridge is one of the most popular types of long-span bridges in china. So far, there are more than 3O cable-stayed bridges completed or under construction, second only to Germany and Japan, and the third place in the world. And the number of long-span concrete cable-stayed bridges has been ranked first in the world.In the middle of 50s, the first modern cable-stayed bridge was built in Sweden. For more than 40 years, the development of cable-stayed bridge has a strong momentum. In the middle of 70s, China began to build concrete cable-stayed bridges. After the reform and opening up, the momentum of the construction of cable-stayed bridges in China has been on the rise.

Q: How to choose the right sling?: According to the current market situation of wire rope, manganese phosphating coating of steel wire rope price is higher than that of plain steel wire rope, and prolonging the service life of much higher than the rate of price increase, so the phosphating coating steel wire rope daily use fee is only about 30% of the plain steel wire rope, the average daily use of lower cost, higher quality and price stability is. Replacement of wire rope smooth upgrade.Lifting equipment commonly used wire rope varieties of phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment optimization of hot galvanized wire rope double - phosphating coating. For reference only.

Q: Does the pressing rope have any influence on the tension value of the wire rope?: Lifting equipment commonly used wire rope varieties of phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope.
