The largest size is up to Φ7x649.
Cable factory has acquired a lot of international scientific and technological achievements and national patents.
Cable factory even participated the editing of many standards, like cable for architectural construction, cable structure technical regulations, membrane structure construction quality acceptance regulations and prestressed steel structure technical regulation.
- Q: What is the difference between cable stayed bridge and suspension bridge?
- Finally, the gravity of the main beam becomes the two vertical force of the tower, so that the force passes to the pier under the tower.There are more cables, and the same reason. There are a lot of bars, that's to distract the main girder from the cables.As a kind of cable of cable-stayed bridge, more than beam bridge spanning capacity is the main bridge of long span bridges. The cable stayed bridge is composed of many cables which are directly connected to the tower. The cable-stayed bridge is composed of pylon, main beam and stay cable. The types of pylon are A, inverted Y, H and single column. The materials are steel and concrete. There are single cable plane, parallel double cable plane and inclined cable plane in the stay cable. The first modern cable-stayed bridge was built in Sweden in 1955 and has a span of 182 meters. At present, the largest span cable-stayed bridge built in the world is the Normandy bridge in France, with a main span of 856 meters. The Shanghai Yangpu bridge, built in 1993, is the largest cable-stayed bridge in China, with a main span of 602 meters
- Q: What are the connections and differences between hooks, slings, rings and heavy truck rings in cranes? What are the hoisting designs?
- A set of wire rope sling series: adhesive wire rope sling, wire rope sling, inserted Aluminum Alloy pressed wire rope sling, no joint wire rope hanger, wire rope sling, multifurcating nylon cord steel wire rope, plastic rope.
- 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: 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: What is the line on the train for?
- It's called catenary. There are two lines up and down. The upper part is called the load line, and the lower one is called the contact line. There is a sling connection between the cord and the contact wire.
- 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's the catch?
- Slings are ropes made of wire or synthetic fiber, used for hoisting.
- Q: What are the precautions for rigging in hoisting works?
- 1. develop good hoisting habits and plan how to hang, lift and unload before lifting.2. prepare: determine the weight of the hanging object and its center of gravity, read the attached document carefully, mark the lifting point and weight data. Only when the center of gravity has been determined can the hook be hung at the right place!3. the crane operator shall be informed of the weight of the suspended object.4. the crane hook shall be hung vertically above the center of gravity of the suspended object.5. lifting heavy pieces, both to avoid damage to lifting objects, but also to prevent damage to the rigging itself. The following conditions shall be observed in order to avoid rotation or fall:(a) single leg rigging, the lifting point shall be perpendicular to the center of gravity of the lifting object.(b) if it is a two leg rigging, the suspension point shall be on either side of the lifting object, with the lifting point above the center of gravity.(c) if it is a three leg and four leg rigging, the suspension point shall be evenly located at the center of gravity of the lifting object, and above the center of gravity of the suspended object.Attention must be paid to the lifting angle, between the vertical and the leg): the greater the lifting angle, the smaller the lifting capacity. Lifting angles of more than 60 degrees are absolutely not allowed!
- Q: What are the specifications for the length, length, and method of operation of the wire rope?
- The fatigue life is three times the same structure of plain steel wire rope, the highest value of contrast test has reached an alarming four times, can be verified by fatigue test, fatigue life ability if they have on their own to do comparative experiments, this test results the most credible, the service life of wire rope and the fatigue life is proportional to a long fatigue life use the same proportion of life extension, the use of lower cost, better stability.
- 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.
