Q:Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
This standard applies to tower cranes defined in GB/T 6974.3.This standard does not apply to mobile cranes equipped with tower cranes. This standard compares with the 5 standards such as GB/T 9462-1999, the main change is as follows:- redefining the type identification principle of tower cranes and eliminating the parameter series in JG/T 5037-1993;
Q:Why are there extra placards attached to the tower crane tower?
Because the span of the base is short, the tower is efficient, and the billboard is easy to cause the tower to overturn or bend.
Q:What is the insulation resistance of tower crane?
Two. Safety regulations for tower cranes GB 5144 - 20068.1.3 tower crane metal structure, track, all electrical equipment metal shell, metal line pipe, safety lighting transformer, low voltage side should be reliable grounding, grounding resistance is not more than 4 ohms. Repeated earthing resistance is not greater than l0. The selection and installation of the earthing device shall comply with the relevant requirements of the electrical safety.The insulation resistance of the 8.1.7 main circuit and control circuit shall not be less than 0.5M ohm.
Q:What does "automatic tower crane" mean less than 100 tons per metre?
When you are working on this crane, the weight between the weight and the weight to the horizontal distance of the crane Center shall not be greater than 100 tons.For example, if the weight and crane center level distance is 10 meters, the maximum weight is 10 tons; if it is 20 meters, the maximum lifting weight is 5 tons; if it is 40 meters, the maximum lifting weight is 2.5 tons.
Q:Which is the main basis for the disassembly and assembly process planning of tower cranes?
.0.11 tower cranes should be prepared before the installation of special construction program, and should include the following contents:1 project overview;2 installation location, plane and elevation;3 types of tower cranes and technical parameters of performance;4 basic and attachment device settings;5, climbing conditions and adhesion nodes detail;6 installation sequence and safety quality requirements;7 weight and suspension position of main mounting parts;8 installation of auxiliary equipment type, performance and layout;9 power settings;10 construction personnel allocation;11 rigging and special tools;
Q:What kind of tower cranes are available? How about the scope of all kinds of tower cranes?
Tower crane is divided into fixed tower crane, mobile tower crane, jack up tower craneThe mobile tower crane is divided into track type, tire type and automobile typeThe jack up tower crane is divided into two parts: internal climbing type and attached typeUsage: loading and unloading concrete by hanging tank for general construction and installation
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:What are the parts of a tower crane? What are their main functions?
The tower crane is mainly composed of a tower body, door frame, tower, tower cap, boom, arm and other metal structure and balance hoisting, luffing, slewing mechanism operation, composition and electrical system and safety device etc.!
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:In the case of tower crane operation, the operation should be stopped
In case of six or more gales, heavy rain, heavy fog, heavy snow or tower crane, you should stop working
