Q:How do you tie the wire rope?
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 specifications for the length, length, and method of operation of the wire rope?
Users need high quality steel wire rope, it should be long life and high quality stable and reliable wire rope.
Q:Why do not different kinds or different sizes of slings and slings are used together?
Choose proper slings and slings according to the specific conditions of the heavy loads; no heavy weights are allowed to be attached directly with the hooks, and no different kinds are allowed
Q:Is the sling the same thing as the rigging?
I have also struggled with this concept before, and I consulted the professionals specializing in rigging. I say you should be able to understand the sling, lifting heavy rigid fetching device operation means, that is to say can directly take hanging items, mainly include: grab, clamp, suction and special sling and rigging, etc.; refers to the lifting items, tie hook combination device with flexible. In the article, usually made from high strength flexible parts (steel wire rope, lifting chain, artificial fiber tape) with end ring, hook, shackle assembly.
Q:What is the safety factor of the wire rope as a motor lifting equipment, slings and slings?
1 phosphating coating steel wire rope (patent products), steel phosphating manganese or zinc manganese by wire surface is very wear-resisting, effectively inhibit the occurrence of fretting wear, is a substitute for plain steel wire rope upgrade, service life far beyond the structure of smooth steel wire rope, wire rope including imported from developed countries such as Germany and Japan (currently the rope is about three times of phosphating, smooth rope after may also be able to improve the phosphating film 3-60 g / M 2, wire drawing no longer after phosphating processing, direct twisting wire rope), has been in China copycat wire rope technology innovation. The innovative technology is suitable for almost all kinds of high-quality carbon steel wire rope varieties, such as elevators, steel ropes, important use steel wire rope and so on.
Q:What are the specifications for the rigging?
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 wear-resistant steel wire surface treatment, corrosion resistance to enhance, not easy to wear and corrosion fatigue life of the steel wire rope large increase, fatigue life is three as structure of plain steel wire rope, the highest value of contrast test has reached an alarming four times, can be verified by fatigue test, fatigue test machine if they have on their own to do comparative tests, this test results most credible, the service life of wire rope and the fatigue life is directly proportional to the fatigue life, long service life with the proportion of prolonged use of lower cost, better stability, phosphating coating of steel wire rope is patent technology production
Q:What is the influence of lifting angle on rigging?
The vertical lifting is the best scheme for lifting. The smaller the angle between the sling and the vertical is, the greater the angle is, the greater the force the sling will bear. The sling will be easily broken off, which will lead to an accident, which is for reference only
Q:What are the precautions for rigging in hoisting works?
The sling shall not be allowed to repair or reprocess itself (welding, heating, heat treatment, surface chemical treatment). If such treatment must be carried out, it shall be sent back to the original manufacturer or under the guidance of the experts of the original factory.
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.
Q:Is rope sling good business and high profit?
With an annual output of 1 million 800 thousand tons of steel China ranked first in the world, is the first world phosphating wire rope wire rope surface treatment inhibited fretting fatigue to prolong the useful life (fatigue life), business wire rope and rigging, ordinary product profit, if can be linked to the manganese phosphating coating of steel wire rope, the profit is very high
