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.

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:Does the pressing rope have any influence on the tension value of the wire rope?: Lifting equipment commonly used wire rope varieties of phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope.

Q:What are the selection principles for lifting cranes?: Selection should take into account the performance of the crane (ie operation capacity), ease of use, hoisting efficiency, hoisting capacity and duration requirements.

Q:What are the dangerous sections of the crane hook?: The sling tension A-A section on the one hand, the hook has straightened trend; also by the effect of bending moment on the other hand. Because the moment in this section, the bending stress is maximum, this section is a dangerous section.

Q:What are the specifications for the rigging?: Because the demand is more difficult to buy, to ask the producer of several wire rope, please note in the purchase, purchase invoice must indicate the name of wire rope, such as phosphate coated wire rope, prevent illegal infringement of their legitimate rights and interests of enterprises, in addition, patent products are generally in the rope on the outer packing of a patent spraying mark, warranty due the main technical indicators, such as the phosphating film type and film weight (have an important impact on the weight of phosphating film size, wear resistance and corrosion resistance of the service life of the wire rope, for reference only)

Q:What is the name of the wire above the train?: The contact wire is mostly made of steel aluminum core, that is, the outside is made of steel, and the main part is the friction part of the pantograph. To ensure the conductivity and wear resistance, the aluminum core is mainly to ensure the conductivity. Copper and aluminum composite wires have also been used as contact wires.

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: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 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.
