Q:What are the requirements for jack up and plus section of jack up tower crane?
When lifting, a standard section is hoisted on the imported beam or introduced platform. Then open the pins or bolts connecting the standard section with the slewing support. Start the oil pump, so that the cage in the standard section of the outward sliding, until the release of a standard section position, and then imported beam or imported platform on the standard section into the connection. This completes a process.
Q:Do self lifting tower cranes allow a small swing of the boom in jacking operation?
The upper working structure of the attached tower crane is connected with the jacking sleeve frame, and a jack jack is mounted on the top lifting jacket frame. The upper crossbeam of the jack is connected with the jacking frame, and the lower cross beam is provided with a movable claw, and the lower supporting point can fall on the step of the standard section of the tower body. During lifting, first trim jib and balance arm, unlock the top are connected with a lifting sleeve frame with the standard section, start lifting system, lifting jack will superstructure.
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 construction cranes? 50
The most common are tower cranes, elevators, and freight lifts. The big construction enterprise also has the track type tower crane
Q:Emergency treatment of interrupted electricity during lifting of tower crane
It is very dangerous to stop the electricity during the lifting of tower crane. Because the slewing brake is missing, the tower crane is very dangerous because the wind rotates.
Q:What kind of equipment must be installed on luffing trolley of horizontal luffing tower crane?
It must be installed:To prevent the trolley cable broken car slip away;
Q:Does tower crane belong to special equipment?
Tower crane is a high-altitude operation, the type of work belongs to special types of work, equipment belongs to special equipment.
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 characteristics of a tower crane?
Classification and characteristics of tower cranesAccording to whether or not there is a walking mechanism, it can be divided into movable tower crane and fixed crane.Mobile tower cranes can be divided into four types: track type, tyre type, automobile type and caterpillar type according to the difference of walking device.The track type tower crane tower body is fixed on the walking underframe, and can be operated on the specially designed track. The utility model has good stability, can walk with load, and has high work efficiency, so the utility model is widely used in construction and installation engineering.The wheel type, the automobile type and the crawler type tower crane have no track device, and they are easy to move, but can not walk with load and have poor stability.The fixed tower crane can be divided into two types: the attached self lifting type and the internal climbing type according to the different installed positions:The attached tower crane can rise as the building rises. It can be applied to the high-rise building. The structure of the crane can only bear the horizontal load from the crane, but it is easy to use, but it occupies more steel structure;The internal climbing crane in the interior of the building (elevator, staircase), up through a set of system and improve the lifting bracket, is complicated, but occupy steel less, do not need to be installed, all the weight and load by building bear.
Q:Are there any special requirements for the installation of wall fittings of tower cranes?
The angle of the two member of the wall shall not be less than 60 degrees and shall not exceed 90 degrees;
