Product Range:Chain sling factory mainly produce high-tensile lifting chain, high-tensile chain sling, round link chain and steel compact chain for scraper conveyor and auxiliary part for mine chain.
Equipment:Chain factory has chain making machine, flash butt welder, stretcher from WaFiOs (german) and sPEcTROMaXx brand metallurgical analysis spectrograph.With the expansion of the market share in recent years, the factory has built 17 chain production lines, 3 chain sling assembly lines and 2 ring welding lines.
Scientific achievements:Mining chain obtained Ma certificate. Lifting chain obtained cE certificate and participated in the compose of GB/T24816 “Short link chain and hoists lifting chain with grade eight ordinary precision chain”. The chain adopts high-quality special steel material from the domestic and foreign market and produced in accordance with the standard of En818-2, gB/ T24816-2009, GB/T12718-2009, Q/JL018-2012.Production range is Φ6-Φ48mm.。
Angle β≤45°when the chain sling was used. If unspecified it defaults to the value. Angle βis the angle between chain segments and the plumb line
- Q: What tools are slings in lifting operations? What is the function of the slings?
- Sling made forms are more commonly used in engineering with inserting end ring and inserted nonpolar (Universal) slings in hoisting work are the steel wire rope is connected with a hook, shackle, sling made of various styles, for lifting, or binding.
- Q: What is the difference between cable stayed bridge and suspension bridge?
- Finally, the gravity of the main beam becomes the two vertical force of the tower, so that the force passes to the pier under the tower.There are more cables, and the same reason. There are a lot of bars, that's to distract the main girder from the cables.As a kind of cable of cable-stayed bridge, more than beam bridge spanning capacity is the main bridge of long span bridges. The cable stayed bridge is composed of many cables which are directly connected to the tower. The cable-stayed bridge is composed of pylon, main beam and stay cable. The types of pylon are A, inverted Y, H and single column. The materials are steel and concrete. There are single cable plane, parallel double cable plane and inclined cable plane in the stay cable. The first modern cable-stayed bridge was built in Sweden in 1955 and has a span of 182 meters. At present, the largest span cable-stayed bridge built in the world is the Normandy bridge in France, with a main span of 856 meters. The Shanghai Yangpu bridge, built in 1993, is the largest cable-stayed bridge in China, with a main span of 602 meters
- Q: Which brand is better for imported rigging?
- Germany's mechanical products are better, quality world-class, CarlStahl sling rigging is Germany's old brand.
- 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: What's the sling for a movie?
- WIA, is used to protect the athlete's device is generally with a strong rope tied to the athlete's protection belt.
- Q: What torture refers to the lever and the sling
- This is a torture peculiar to china. The knee joint has the smallest range in the major joints of the limbs, and the length of both ends of the thigh and leg is favorable to the prisoners. The lever principle is used to compel the victims with lesser intensity. Key points of anti joint using tiger stool:1, the victims in the sitting position (arms tied or tied into the penalty, the pulling force cross) it will aggravate the leg ligament, and supine position due to hip joint ligament relaxation, legs relaxed, will weaken the degree of pain;2, the leg is tied in the lap of the thigh, rather than the following parts. Because the function of the tiger stool is to pull the joints and ligaments of the victim's leg and to cause a dislocated knee, not to break the victim's leg. Because the broken leg, the fibula needs a lot of power, the pain time is short (the victim will soon fainted), do not meet the punishment, both to torture the victims and their own labor saving requirements.According to records, when the victim is on a tiger stool, he usually gets sweaty when he pad three bricks. When the five bricks are completely dislocated, the person will faint. The torturer usually each brick will be suspended for a while, the victims of the pain continued for a period of time after aggravated torture efforts. Women's ligaments are usually softer than men, so they suffer longer on tiger stools and tend to faint when they are added to six bricks, the longest of which is eight bricks.
- 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 installation steps for crane beams?
- Installation of crane beam elevation as a negative deviation, between surface and column bracket crane beam flange into the iron plate. But the shim shall not exceed three layers and shall be placed under the end of the crane beam or under the stiffener, and the area of the shim shall not be less than 60% of the part of the contact area between the crane beam and the bracket.
- Q: What are the specifications for the length, length, and method of operation of the wire rope?
- The fatigue life is three times the same 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 life ability if they have on their own to do comparative experiments, this test results the most credible, the service life of wire rope and the fatigue life is proportional to a long fatigue life use the same proportion of life extension, the use of lower cost, better stability.
- Q: How to choose the right sling?
- Commonly used slings and slings are lifting belts, lifting chains and wire ropes. Slings and slings must be matched with lifting equipment, such as 5 tons or 10 tons. Cranes shall be marked with maximum lifting weight. Lifting belt will not damage the hoisting object but poor wear resistance, easy maintenance but large weight lifting chain, rope buckle range but the broken wire after easily scratch objects and operators, each have advantages and disadvantages, to meet their own needs is the best lifting.Phosphating coating of steel wire rope production technology patent, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just increase the steel wire wear phosphating process, phosphating of steel wire surface after the abrasion resistance and corrosion resistance is greatly improved, the use of direct phosphating steel wire twisting steel wire rope (steel wire after phosphating not drawing). 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 plain steel wire rope, wire rope is 2-3 times of imports (laboratory comparable conditions) with the research on the wear resistance of phosphating, and greatly enhance the possibility of. Manganese phosphating is wear resistant phosphating, which can completely solve the wear problem in the use of wire rope.
