- Q:They are used for slings, ropes, chains, suspenders, hand hoists, right?
- The use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, manganese phosphating coating can greatly improve the wear resistance and corrosion resistance of the steel wire surface, the fatigue life of the phosphating coating steel wire rope is 3-4 times of smooth wire rope, with the research on the wear resistance of the phosphating liquid, as well as to further improve the possibility of. According to the current market price of the phosphating coating steel wire rope, phosphating coating steel wire rope daily use cost is just plain steel wire rope about thirty percent of phosphating coating steel wire rope is a substitute for plain steel wire rope upgrade, for reference only.
- Q:What is the name of the wire above the train?
- It's called catenary. There are two lines up and down. The upper part is called the load line, and the lower one is called the contact line. There is a sling connection between the cord and the contact wire.
- Q:What are the specifications for the rigging?
- Crane users need high quality steel wire rope, it should be long life and high quality stable and reliable wire rope. Fretting fatigue is the main cause of wire rope failure in atmospheric environment
- Q:20 tons sling rope, steel wire or chain?
- The strength of the steel wire rope can reach 2000-2500MPa, and is made by using cold drawn steel wire. The tensile strength is much higher than that of the chain, so that the weight of the sling can be reduced, the production efficiency can be higher, and the steel wire rope is preferred.
- Q:What does the inspection of rigging involve?
- The stainless steel wire rope is mainly made of 304 or 316 stainless steel. The anti-corrosion effect is excellent, but the price is expensive4. carbon coated steel wire rope, wire rope based on polyethylene, polypropylene or nylon outer coating5. smooth wire rope, short service life, the market demand is declining, the phosphating coating steel wire rope round out.
- Q:Which sling manufacturer is more reliable?
- A variety of commonly used wire rope phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated 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.
- Q:What are the selection principles for lifting cranes?
- It can adapt to the conditions of road, hoisting, plane layout and equipment, machines and tools, and give full play to its technical performance.
- Q:What is the safety factor of the wire rope as a motor lifting equipment, slings and slings?
- 3. stainless steel wire rope, the use of stainless steel wire rope system, such as 304 or 316 stainless steel, the price is relatively expensive, the stainless steel wire for manganese phosphating coating (stainless steel wire need special phosphating phosphating formula), you can use the same life greatly extended.
- Q:What are the precautions for rigging in hoisting works?
- 1. develop good hoisting habits and plan how to hang, lift and unload before lifting.2. prepare: determine the weight of the hanging object and its center of gravity, read the attached document carefully, mark the lifting point and weight data. Only when the center of gravity has been determined can the hook be hung at the right place!3. the crane operator shall be informed of the weight of the suspended object.4. the crane hook shall be hung vertically above the center of gravity of the suspended object.5. lifting heavy pieces, both to avoid damage to lifting objects, but also to prevent damage to the rigging itself. The following conditions shall be observed in order to avoid rotation or fall:(a) single leg rigging, the lifting point shall be perpendicular to the center of gravity of the lifting object.(b) if it is a two leg rigging, the suspension point shall be on either side of the lifting object, with the lifting point above the center of gravity.(c) if it is a three leg and four leg rigging, the suspension point shall be evenly located at the center of gravity of the lifting object, and above the center of gravity of the suspended object.Attention must be paid to the lifting angle, between the vertical and the leg): the greater the lifting angle, the smaller the lifting capacity. Lifting angles of more than 60 degrees are absolutely not allowed!
- Q:What is the difference between cable stayed bridge and suspension 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.China has been developing the concrete cable-stayed bridge mainly. In recent years, China has begun to build a hybrid cable-stayed bridge with steel and concrete, such as the Shantou stone bridge, the main span 518m, and the Yangtze River Third Bridge in Wuhan, the main span 618m. Steel box cable-stayed bridges, such as Nanjing Changjiang second bridge, South Branch bridge, main span 628m, Wuhan military mountain Yangtze River bridge, main span 460m. A few years ago, the Nanpu (main span 423m) and Yangpu (main span 6O2m) bridge built in Shanghai were steel and concrete composite beam cable-stayed bridges.
