Q: What is the difference between cable stayed bridge and suspension bridge?: 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: Where should I pay attention to the formwork?: When the welded steel bar and the formwork are installed together, the following requirements shall be met:The formwork must be fixed on the joint of the load-bearing welded steel frame;When installing the reinforcing steel formwork assembly, the sling shall be tied up according to the hanging point designed by the template.

Q: Is rope sling good business and high profit?: The atmospheric environment should be optimized by the manganese phosphating coating steel wire rope, and the heavy corrosion environment should be preferably galvanized - phosphating double coated steel wire rope.

Q: Do cranes have the same wire ropes, slings, slings and cables?: To be exact, different things are very relevantThe cable belongs to the sling and belongs to the spreaderA wire rope can be made into a wire rope rigging

Q: What is the name of the wire above the train?: 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: Requirements and matters needing attention in hoisting: We often encounter equipment installation, transport and installation work, whether the derrick is lifting or hoisting machinery should pay attention to the following points: (1) the indigenous construction equipment for handling mobile rolling method, the rolling rod thickness should be consistent, should buetow annual row width is 50cm long, no gloves in rollers. While loading and unloading piping shall not be greater than 20 degrees slope, raceway erection should be smooth, solid, joints staggered, the rolling speed is not too fast, when necessary to use ropes.(2) in the course of installation, if problems are found, measures should be taken in time, and then continue to be hoisted after treatment.(3) large tower equipment for hoisting derrick, hoists joint operation, the hoist hoisting speed must be roughly the same, to ensure that the tower body of each suspension force roughly uniform, avoid the tower stress uneven deformation.

Q: Why do not different kinds or different sizes of slings and slings are used together?: Choose proper slings and slings according to the specific conditions of the heavy loads; no heavy weights are allowed to be attached directly with the hooks, and no different kinds are allowed

Q: What's the catch?: Slings are ropes made of wire or synthetic fiber, used for hoisting.

Q: Ceiling installation does not allow the use of air nails?: (1) construction materials: common materials are as follows.Wood (different specifications of water, wood, water board), aluminum alloy (plate, profile), steel (steel, flat steel, steel plate), mainly as supporting components.Plastic, plexiglass plate, glass partition plate, outer decorative veneer and heat dissipating plate, copper plate and electrochemical aluminium plate as decorative component.Other accessories such as screws, nails, rivets, finished lamps, adhesives and so on.(2) construction tools: pliers, screwdrivers, hammers, saws, electric hammer, hand according to the curve, a ruler, paint etc..

Q: What are the selection principles for lifting cranes?: It can adapt to the conditions of road, hoisting, plane layout and equipment, machines and tools, and give full play to its technical performance.
