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:Slings and rigging manufacturers, which cost-effective?: Wire rope rigging, manganese phosphating coating steel wire rope is a new technology appearing in recent years. Wire rope has a long service life. Buy wire rope made of phosphating coating steel wire,

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:The wire rope lock can hang a lot of things: The crane used in atmospheric environment, preferably manganese phosphide coating, steel wire rope, heavy corrosive environment, preferred hot-dip galvanized double phosphating steel wire rope, priority wire rope in sea water. Please note that at the time of purchase, in the purchase invoice must indicate the name of wire rope, such as phosphate coated wire rope or 316 stainless steel wire rope, to protect their legitimate rights and interests, in addition, patent products are generally in the rope on the outer packing of a patent spraying label, warranty should be the main technical indicators, such as the type of phosphating film and film, for reference

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: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 connections and differences between hooks, slings, rings and heavy truck rings in cranes? What are the hoisting designs?: Synthetic fiber tape series: flexible sling, sling, ring ring cylinder cylinder eye sling, sling, flat glass, polypropylene flat sling, sling, sling fastening belt, pickling container windproof belt, hand woven tape, tied with tape, nylon, special oil pipeline pipe sling, sling dupont. (flat suspenders can produce 1T-30T, flexible suspenders, which can produce 1T-300T)

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

Q:Does the pressing rope have any influence on the tension value of the wire rope?: According to the current market price of the phosphating coating steel wire rope, phosphating coating steel wire rope daily use cost is just plain steel wire rope about thirty percent of phosphating coating steel wire rope is a substitute for plain steel wire rope upgrade, for reference only.

Q:Is the sling the same thing as the 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.
