Q: Where should I pay attention to the formwork?: When the interlayer height is greater than 5m, the truss formwork or the multi layer support formwork should be adoptedWhen the formwork is supported by a multi layer support, the support plate shall be smooth, the support shall be vertical, and the upper and lower support shall be on the same rigid central line.(5) when the segmental demoulding is adopted, the pivot of the bottom die shall be designed according to the template, and the sections shall be in the same plane, and the height difference shall not exceed 3mm.

Q: They are used for slings, ropes, chains, suspenders, hand hoists, right?: A variety of commonly used wire rope phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope.

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: How do you tie the wire rope?: The price of phosphating coating wire rope is higher than that of smooth steel wire rope, but the unit use cost is lower than the smooth steel wire rope. The test data indicate that fatigue life of phosphating coating steel wire rope is 3-4 times of plain steel wire rope, wire rope life and fatigue life is proportional to, according to the current market price of roughly wire rope, manganese phosphating coating of steel wire rope although the 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, the average daily cost of using only smooth steel wire rope 30-45%, longer service life, lower cost per use, stability and security in the process of using and more cost-effective products, light surface wire rope upgrade, for reference only

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: Slings and rigging manufacturers, which cost-effective?: Crane users need high quality steel wire rope, it should be long life and high quality stable and reliable 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 fatigue life of the steel wire rope large increase, fatigue life is three times the same structure of plain steel wire rope, the highest test value has reached an alarming four times contrast (laboratory comparable conditions), can be verified by fatigue test, fatigue test machine if they have on their own contrast test, this test results the most credible, the service life of wire rope and the fatigue life is directly proportional to the fatigue life, long service life of the same proportion of extension.

Q: What is the safety factor of the wire rope as a motor lifting equipment, slings and slings?: 2. galvanized steel wire rope, including hot-dip galvanizing and electro galvanized two kinds, hot galvanized zinc layer is thick, long use time, galvanized thin, zinc layer thicker, corrosion protection ability is stronger. Because of the corrosion resistance of phosphating coating, the manganese phosphating coating steel wire rope can be used instead of some kinds of zinc coated steel wire rope, such as the B zinc coating in GB8918-2006.

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: 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 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
