Q:How did the tower crane rise on the construction site? Fifteen
It's not a cable, it's a steel bar! Scaffolding
Q:What special operators should be equipped for the installation and disassembly of tower cranes?
According to the requirements of the 2.0.3 specification: tower crane tower crane installation and disassembly operation should be equipped with the following: 1, hold a qualified safety assessment certificate of the project and responsible for the safety of people and machinery management personnel; 2, with construction qualification certificates for special operations of the construction hoisting machinery installation and disassembly, lifting work, special operation signal heavy drivers, riggers and other operations personnel. And an electrician.
Q:What does the lifting mechanism mean in a tower crane?
Magnification, in simple terms, refers to several ropes through the hookIf it is one in and out of two wire rope, that is two magnificationSimilarly, two into two out is four magnification
Q:Why do tower cranes need to be fabricated?
The crane wire rope commonly used varieties of phosphating coating steel wire rope, galvanized steel wire, stainless 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.Phosphating coating of steel wire rope production technology patent, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just add the last bonderizing process, steel wire for rope wear resistance and corrosion resistance is greatly improved, the use of direct phosphating steel wire twisting steel wire rope.
Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
1. Tower crane consists of three parts: metal structure, working mechanism and electrical system. The three main technical parameters are lifting moment, lifting weight and working speed. Lifting moment refers to the boom as the basic arm length maximum amplitude corresponding to the rated lifting weight of product, product or maximum weight with the corresponding inflection point.
Q:Climbing process of an internal climbing tower crane
There are two kinds of climbing mechanisms: hydraulic and mechanical. The hydraulic climbing mechanism consists of a ladder ladder, a hydraulic cylinder, a climbing beam and a support leg. The climbing ladder is composed of an upper and a lower bearing beams, separated by two stories, which are fixed on the wall or side beam of the cylindrical structure when the work is used, and both sides of the ladder stand are provided with steps. The load bearing beam corresponds to the four main limbs of the crane tower, and is equipped with 8 guide rollers, which plays a guiding role when climbing.
Q:What is the brand of ZOOMLION tower crane?
This is not very good answer, the United States originally used Tianshui 213, and then used the Japanese MITSUBISHI, used Schneider, LG, star power, Eaton.How big is the lift? It depends on the size of the motor you use. 24KW motor, the choice is about 100A. 30KW uses 125-150A, 55KW, and 150-180A;Generally 40A contactor is used for turningCar selection of 25A on it.
Q:Operation points of tower crane (tower crane)?
Safe use requires the use of tower crane, issued by the state competent authorities shall abide by the rules and regulations, but also comply with the relevant provisions in the manual: the crane working environment temperature is -20~40 degrees Celsius, the maximum working pressure is 205N/m2, when should stop using the winds of more than 6 level; the same construction site to install more than two sets of tower crane when should pay attention to the location of each tower, take the elevation of different operations, in order to avoid the tower crane jib, balance arm collision accidents; safety device of tower crane, luffing and slewing height, mass and moment limiter, the last two more important, if the two is not detected qualified, will be regarded as the unqualified, because it plays a role to ensure the safety and prevent the tilting of the tower crane. As a construction site, the tower crane torque limiter failure or to replace the operating personnel mistakenly believe that daily only hanging 800-1000kg materials, not what the risk, the results in a process of lifting materials, because of the construction site is narrow, hanging by the operator sight blocked, hanging objects hanging on building the steel frame, caused by tower crane shaking, was the occurrence of major accidents, thanks to the ground work riggers promptly notify the operator immediately stop to avoid rollover accident of tower crane appeared. It is obvious that all safety devices on the tower crane are essential and must be checked regularly to ensure that all the safety devices are in good condition, sensitive and reliable.
Q:What are the climbing claws on the tower crane?
You mean the set section? Used to be rubber, and later found that when the top of the friction is too large, not too good, plus plus the festival, but also always remove the standard section paint, and now basically the pulley
Q:What is the rental price of a tower crane? General site rental more, but also buy more? Ask the industry for an answer?
The rental price of tower crane consists of the cost of advance and retreat yard and the monthly rent of tower crane. The cost of the advance and retreat yard includes the loading and unloading costs, transportation costs, installation costs and monitoring expenses of the tower crane. The rent of the tower crane includes the cost of tower cranes, the cost of tower crane maintenance and the wages of the crane drivers. At present, many sites are using lease way to use tower cranes, so that the occupation of the site will be less rent, investment will be relatively small.
