- 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:20 tons sling rope, steel wire or chain?
- The main - phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope and coated steel wire rope wire rope varieties, for reference only
- 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:How do you tie the wire rope?
- A variety of commonly used wire rope phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment optimization of hot galvanized wire rope double - phosphating coating.
- Q:What are the installation steps for crane beams?
- Crane operation is relatively dangerous, the installation of crane beam should be standardized to ensure the safety of crane operation. How many points should I pay attention to when installing the crane?:(1) the actual elevation of the corbel should be measured before the installation of the steel crane beam, so that the construction error of the elevation can be adjusted when the crane beam is installed, so as to prevent the error accumulation.The installation sequence of crane beam is as follows: installing crane beam, installing auxiliary truss and installing brake beam.(2) crane shall be used by slings, lashing or reliable clamps. The binding point shall be determined according to the weight and length of the crane beam. Generally, the angle of the sling shall be greater than 45 degrees at the ends of the center of gravity of the crane beam.(3) should be placed after the crane beam, the connecting plate is connected with the fixed edge plate and column crane girder structure, to prevent the crane hook loose after crane girder longitudinal and lateral movement of dumping.(4) crane beam correction should be performed in all bolts after installation, to prevent the installation of bolts when the crane beam shift change; prohibited welding in the crane girder under the flange and web on suspension and fixture.(5) adjust the elevation of the crane beam, correct the center line and span after titanium.
- Q:How to choose the right sling?
- The selection of rigging should be adapted to the kind of articles, environmental conditions and specific requirements.The sling to carry out strict inspection, in accordance with safety color to use, if found damaged sling can not be reused, need for scrap processing.The slings used for lifting operations must be of the same length.The sling shall not exceed its rated lifting capacity, and the sling shall not exceed its maximum safe working load.
- 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:How much is the crane arm of the tower from the residential building recently?
- No aluminum conductor or steel shall be used as grounding or ground wire for the installation of tower cranes. A bolted wire must have an end. Grounding is mainly made up of the following three ways:1. the grounding body adopts a regular grounding pile, or a 33*4.5 long 1.5m steel tube, or a 70*70 long 1.5m angle steel.2. the floor is made of steel plates or other metal plates with an area of 1 square meters. The ground is deep from the ground 1.5m.3. a copper conductor with a cross-section of not less than 28 mm or a steel conductor with a cross section of not less than 50 mm is buried in the slot and its embedment length is determined by the grounding resistance.In the above three ways, the grounding body leads the copper conductor, the sectional area shall be no less than 25, if the soil is not conductive, the sodium chloride (salt) can be embedded in the soil. Then irrigation. For walking crane, each rail must be grounded, and the two tracks are connected by wires. Electrical connections should also be made between the two rails, with a resistance of no more than 4.
- Q:Why do not different kinds or different sizes of slings and slings are used together?
- Or different specifications of slings and slings are used together; the carrying capacity of the sling shall not exceed the rated lifting capacity; the sling shall not exceed the safety load; the lifting crane shall check whether the connection point is firm and reliable
- Q:Why are the suspension bridges a main cable, even a n multi sling, not a bridge directly from the tower?
- 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
