Q:What does the inspection of rigging involve?
The stainless steel wire rope is mainly made of 304 or 316 stainless steel. The anti-corrosion effect is excellent, but the price is expensive4. carbon coated steel wire rope, wire rope based on polyethylene, polypropylene or nylon outer coating5. smooth wire rope, short service life, the market demand is declining, the phosphating coating steel wire rope round out.
Q:Why are the suspension bridges a main cable, even a n multi sling, not a bridge directly from the tower?
The main weight of a bridge is not the car or train on it, but the road itself, that is, the road we see. Now let's analyze this:We analyze it with a pylon. The two sides of the pylon are symmetrical stay cables which connect the main beam of the pylon through the stay cables. Now suppose that only two towers on both sides of the cable, symmetrical each one of the two cables subjected to beam gravity, two symmetrical of the cable along the direction of the force, according to the stress analysis, the stress can be decomposed into a horizontal and vertical force to a downward force a vertical force; and the same on the right side of the force can be decomposed into the right level of a downward force; the two force is symmetrical, so the two level of the left and right horizontal force cancel each other out,
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.
Q:What torture refers to the lever and the sling
China used suspension has a special method commonly used, is the only victims of hanging to toe the height, so that the victims are difficult to completely rely on the wrist or thumb under the weight of the whole body, and can not completely rely on the toes to support the body, is very painful, this is the unique China torture method.There is a special way of suspension is relatively rare, is the so-called "monkey holding pile", will be the victims before the hands (also can only bind the thumb to hold the two) was forced to bend the knee, the knee bend into a stick with a rope, lifting the stick ends (also stick to a certain height of the frame other instruments). When the victims of the buttocks, genitals and soles of the feet completely exposed, for the use of other means torturer. In this gesture, the wrist (thumb), knee joint, waist and neck will be squeezed, twisted and pulled by the weight of each part of the body. It is very painful, and Yang Kaihui has been subjected to the punishment.
Q:Does the pressing rope have any influence on the tension value of the wire rope?
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, up to 5 times, with the research on the wear resistance of the phosphating liquid, as well as to further improve the possibility.
Q:Do cranes have the same wire ropes, slings, slings and cables?
A steel wire rope is a common wire rope, and a sling is a special tool for lifting some goods. The sling is a sling tool made of wire ropes
Q:What are the specifications for the length, length, and method of operation of the wire rope?
The use of wire rope in the atmospheric environment, mainly caused by the failure of wire rope is fretting fatigue, at present, the wire rope for the first time in the field of fretting fatigue control measures is the phosphating coating steel wire rope patent technology production, steel wire after manganese phosphating or zinc manganese treatment, wear resistance, enhance the surface of steel wire that is not easy to wear and corrosion resistance of the fatigue life is greatly improved
Q:What is the name of the wire above the train?
The catenary provides 25 thousand volt power frequency alternating current for the locomotive, according to the locomotive model difference, adopts the direct step-down, the frequency conversion power supply or the AC and DC conversion power supply, this is mainly for the speed regulation convenience.
Q:What are the precautions for rigging in hoisting works?
When lifting heavy objects, heavy is prohibited to stand.
Q:Notice of tower crane?
The metal structure of the tower crane, the track and the metal shell of all the electrical equipment shall have reliable earthing devices, and the grounding resistance shall not be greater than 4 ohms, and lightning protection devices shall be set up.Fourth. Pole arrangement, each attachment device attached to the wall and spaced distance should be in accordance with the provisions of the original factory, homemade bar design calculations should be.
