2. The main cause of wire rope failure is fretting fatigue. The wire rope should be checked frequently to prevent rope breaking accident. When the number and diameter of broken wire of wire rope decrease to meet the national standard, the wire rope must be replaced. Please refer to GB / t29086-2012 national standard for safe use and maintenance of wire rope for maintenance, And according to GB / t5972-2009 crane wire rope maintenance and installation inspection scrap national standard for inspection and scrap

the main varieties of steel wire rope are selected according to the actual working conditions:

manganese phosphating coating steel wire rope is preferred in atmospheric environment, and hot galvanizing phosphating double coating steel wire rope is preferred in corrosive environment< The phosphating coating steel wire rope (Chinese patent) has been phosphated by manganese or zinc manganese system. The wear resistance and corrosion resistance of the steel wire surface are improved. The lubricating grease penetrates into the pores of the phosphating film, which has an excellent friction recing effect and effectively inhibits the occurrence of fretting wear. It is an upgraded proct of smooth steel wire rope. Its service life in atmospheric environment far exceeds that of smooth steel wire rope with the same structure, Including imported wire rope (at present, the fatigue life of phosphating rope is about 2-3 times that of smooth rope, the fatigue life can be compared through fatigue test, and the service life may be greatly improved with the in-depth study of wear-resistant phosphating liquid in the future. Phosphating film 3-60g / m2, steel wire is directly twisted without drawing after phosphating. Attention: Zinc Phosphating for drawing and manganese phosphating for rope making steel wire should not be confused. This technology is suitable for many kinds of wire rope proction, such as elevator wire rope, important use wire rope, mine wire rope, anti rotation wire rope, oil proction wire rope, pile driver wire rope, etc. (the paper of phosphating coated wire rope is available for free download in the Network Library)
2. Galvanized steel wire rope includes hot-dip galvanizing and electro galvanizing. The zinc layer of straight up hot-dip galvanized steel wire is thicker. The thicker the zinc layer is, the stronger the anti-corrosion ability is. The longer the service time is, and the thinner the electro galvanizing is. Hot dip galvanized steel wire rope shall be selected for use in water. Because the phosphating coating has certain anti-corrosion performance, manganese phosphating coating steel wire rope can replace some kinds of thin zinc galvanized steel wire rope, such as atmospheric environment but humid high temperature environment
3. Stainless steel wire rope, which is twisted with stainless steel wire, such as 304 or 316 stainless steel, has higher corrosion resistance than hot-dip galvanized carbon wire rope, which is relatively expensive. Manganese phosphating coating is applied to stainless steel wire (special phosphating formula is required for phosphating stainless steel wire), which can greatly prolong its service life
4. Plastic coated steel wire rope, based on carbon or galvanized steel wire rope, is coated with polyethylene and polypropylene on the outer layer of steel wire rope or strand rope
5. Smooth steel wire rope was proced in England in 1834 and Tianjin No.1 steel wire rope factory in 1939 (bankrupt in 2005). With phosphating coated steel wire rope entering the market in large quantities, it will be completely eliminated by phosphating coated steel wire rope.

3. There are a lot of lifting machinery, with different categories and varieties. According to the different structure and performance, the lifting machinery used in bridge construction can be generally divided into three categories: light and small lifting equipment, bridge type lifting machinery and boom type crane

1. Light and small lifting equipment, such as Jack, hoist, hoist, etc

2. Type of bridge crane, such as beam crane, gantry crane, etc

3. Jib type cranes, such as fixed slewing crane, tower crane, truck crane, tire crane, crawler crane, etc

in a certain range, lifting machinery is also called crane, which belongs to the category of material handling

if you want to get to know each other, you can check the pictures of the corresponding machines on the Internet

if you are willing to buy a machine, I will introce a website to you, xunjie.com, ha ha, listen to the name, you will know that it is a station looking for machinery

this station is not bad. It's a complete machine with clear pictures, which is convenient for you to understand.

5. I often provide wheel forging proction service for crane manufacturers. I don't know what kind of manufacturer you need. Famous are Weihua, mining, Dafang, etc.

6. The elevator can't be transformed at will! As for the certificate you said is the special equipment operator certificate, lifting machinery installation and maintenance, lifting machinery electrical installation and maintenance of these two kinds of operator certificate. In addition, the crane inspection, the need to obtain the certificate of crane inspector, inspector certificate years enough, you can also obtain the inspector. The appeals are all certificates issued by the China Special Equipment Inspection Association and the Bureau of quality supervision
in addition to the Quality Supervision Bureau, there is the IC card of the Safety Supervision Bureau. Normal qualification needs some of the former, but to do related work at the construction site also needs the certificate of Safety Supervision Bureau, which means that you can carry out related work safely. In addition, if you have any questions, you can send me a private letter. I'm engaged in related work and hope to adopt it. I like it. Thank you.

1. The main features are different

crane:

its driving cab and lifting control cab are integrated into one, which is evolved from crawler crane (crawler crane). The crawler and walking bracket of the walking mechanism are changed into chassis with tires, which overcomes the shortcomings of crawler shoes of crawler crane (crawler crane) causing damage to the road, and belongs to material handling machinery

conveyor:

the direction is changeable, the conveying direction can be changed flexibly, and the maximum can reach 180 degrees; Conveyor, each unit is composed of 8 rollers, each unit can be used independently, can also be connected with multiple units, easy to install; The conveyor is flexible, and the ratio of the longest state to the shortest state of a unit can reach 3 times

Crane: in 10 BC, Vitruvius, an ancient Roman architect, described a kind of lifting machine in his architectural manual. This kind of machine has a mast with a pulley at the top of the mast. The position of the mast is fixed by the guying cable. The winch is used to pull the cable through the pulley to lift heavy objects. Some overweight machinery can use two masts to form a herringbone shape to move the lifting object horizontally, but the range is very small and the operation is very difficult

conveyor: the ancient Chinese high rotation drum car and water lifting overturning car are the rudiments of modern bucket elevator and scraper conveyor; In the middle of 17th century, aerial cableway was used to transport bulk materials; In the middle of the 19th century, various modern structure conveyors appeared one after another

3. Different applications of

cranes:

1. Single and double beams: generally, the lifting capacity is less than 50t, the span is less than 35m, and there is no special use requirement, so the single main beam type should be selected. If the width of the door leg is required to be large, the working speed is high, or the heavy and long parts are often lifted, the double beam gantry crane should be selected

2. Span: the span of gantry crane is an important factor affecting the quality of the crane. In the selection, the span should be reced as much as possible on the premise of meeting the service conditions of the equipment and meeting the span series standards

3. Determination of wheelbase: it can meet the stability requirements of gantry along the crane track direction, the overall dimensions of goods should be able to smoothly pass through the outrigger plane steel frame, and the wheelbase B should be proportional to the span s, generally taking the wheelbase B = (1 / 4-1 / 6) s

4. Space dimension: in the work, there should be a certain space dimension between the external dimension of gantry crane and the cargo and transport vehicle passage in the yard, so as to facilitate the loading and unloading operation. Generally, when the transport vehicles are loaded and unloaded within the span, a distance of more than 0.7m shall be kept between them and the door leg. When the spreader is not working, there should be a distance of more than 0.5m between the spreader and the transport vehicle. When the goods pass through the door leg, there should be a distance of more than 0.5m

Electrical equipment: it shall comply with the relevant provisions of GB / t14406-1993 for general purpose gantry crane

6. Energy saving application: bridge crane is a kind of lifting machinery widely used in instrial and mining enterprises. A locomotive depot is equipped with several bridge cranes, which are used frequently every day and have a large workload

Conveyor: widely used in mining, metallurgy, building materials, chemical instry, electric power, food processing and other instrial fields. In coal mines, metal mines, steel enterprises, ports, cement plants and other places can see a large number of leather machine applications
