Q:What's the catch?

The type of slings 1. slings are mainly metal slings and synthetic fiber slings in two main categories. 2. metal slings are mainly wire ropes, slings, chains, slings and so on. 3. synthetic fiber slings are mainly made of nylon, polypropylene, polyester, high-strength and high modulus polyethylene fiber for rope and belt slings.

Q:What are the installation steps for crane beams?

The crane beam and track shall be corrected after the main component is fixed. Fix immediately after correction, in order of fixation, bolt first and then weld.

Q:What is the line on the train for?

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:Do cranes have the same wire ropes, slings, slings and cables?

My understanding is different. The cable refers to the cables used for power supply or the cables used for hanging lamps.

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:Ceiling installation does not allow the use of air nails?

Installation notes: installation should pay attention to the following three points.When installing, if there are many chandeliers, we should pay attention to their location, length and length, and install the ceiling lamp while installing the ceiling, so that the position and height of the lamp can be adjusted on the basis of the ceiling and joist.The hanger on the ceiling must be made by direct out method and by adding bushing. The method of adding sleeves is good for installation, and it can ensure the integrity of the ceiling panel. The boom that is directly out of the ceiling can not be easily drilled when installing, and sometimes the method of installing the suspender first and cutting the hole of the panel is adopted, but the decorative effect is affected.The boom should have a certain length of thread for adjusting height. Attention should be paid to the reliability of the hanging light box under the suspender and suspender.

Q:Is rope sling good business and high profit?

1. phosphating coating steel wire rope, steel wire by manganese or zinc manganese phosphating, corrosion resistance and wear resistance steel rust resistance comprehensive jump, life is the same structure of plain steel wire rope 3 times (note the use of zinc phosphating and drawing rope with distinction, although Tianjin bonderizing Jiangsu have been a number of production enterprises, there is still a shortage of supply and demand)2. galvanized steel wire, hot-dip galvanized and galvanized3. stainless steel wire rope, 304 or 316 stainless steel4. coated steel wire rope, wire rope on the basis of the outer coating of polyethylene or polypropylene5. smooth steel wire rope, will be phosphating coating steel wire rope completely eliminated.

Q:What is the influence of lifting angle on rigging?

Slings are usually steel wire ropes or chain slings. Wire ropes have manganese phosphating coating, steel wire rope, galvanized steel wire rope, manganese phosphating coating, steel wire rope is new technology product, and fatigue life is three times of smooth steel wire rope.

Q:They are used for slings, ropes, chains, suspenders, hand hoists, right?

The use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, manganese phosphating coating can greatly improve the wear resistance and corrosion resistance of the steel wire surface, the fatigue life of the phosphating coating steel wire rope is 3-4 times of smooth wire rope, with the research on the wear resistance of the phosphating liquid, as well as to further improve the possibility of. 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: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.
