How to choose the right sling?
The selection of rigging should be adapted to the kind of articles, environmental conditions and specific requirements.The sling to carry out strict inspection, in accordance with safety color to use, if found damaged sling can not be reused, need for scrap processing.The slings used for lifting operations must be of the same length.The sling shall not exceed its rated lifting capacity, and the sling shall not exceed its maximum safe working load.
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.
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.
