Product Description:

QTZ80(5513AS) tower crane tower crane is novel hoisting and conveying machinery which is designed by fully utilizing the group technology, the combinational design technology and the finite element analysis technology and taking the tower crane microcomputer design platform as a tool.
The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the maximum working amplitude of 56m, the independent lifting height of 40m, the adhesion lifting height of 150m, the rated lifting moment of 710kN•m and the maximum lifting moment of 853.2kN•m. All the performance parameters and technical indexes of the crane meet or surpass national standards.
The crane features advanced parameters, excellent and reliable properties, attractive appearance, high quality, simple and practical structures, advanced safety devices, convenient maintenance, safe usage and reasonable prices, and is ideal construction machinery for many construction enterprises.

The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

Q:When the tower crane top height is more than meters
Three, lifting and installation, demolition works(1) lifting projects with unconventional lifting equipment and methods with single lifting weights of 100kN and above.
Q:Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
the requirement for selecting the steel quality group based on the results of brittle fracture evaluation of steel is increased;Environmental requirements and nondestructive testing requirements for welds are increased;- increased the number of institutional requirements;- increased the type and requirements of some of the units;- - increased technical data requirements that manufacturers should provide;- added some information labeling requirements;- mounting and climbing requirements are increased;The inspection requirements of tower crane are described in detail.
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:Emergency treatment of interrupted electricity during lifting of tower crane
The rotating gear shall be immediately inserted into the screw or wood, while the power supply shall be checked rapidly to remove the trouble.
Q:How often should the crane be inspected regularly?
Crane safety supervision regulations twenty-fourth in lifting machinery safety regular supervision and inspection cycle for two years, elevator and manned elevator safety regular supervision, inspection cycle for a year.Eighteenth lifting machines should check the lifting machines regularly, including annual inspection, monthly inspection and daily inspection:I. at least one full inspection shall be carried out annually on the lifting machinery used.The load test can be carried out by lifting the heavy load which is equivalent to the lifting weight, and checking the safety performance of the mechanism such as lifting, running, turning and amplitude according to the rated speed.Lifting machines which have not been used for more than one year should be examined comprehensively before use.Crane in case of four or more earthquakes or major equipment accidents, outdoor work crane after more than nine winds, should be used before a comprehensive inspection.
Q:What are the necessary safety devices on a tower crane?
(6) lightning protection and anti electromagnetic wave induction device;For the crane whose hinge height is over 50m, the lightning arrester shall be installed according to the actual situation and the electromagnetic interference shall be taken.(7) tower crane shall install limit torque coupling in order to prevent slewing overload(8) anti stripping device prevents the rope from working position(9) the device prevents the rope from breaking and the trolley is free to slide(10) the car prevents the broken axle device, prevents the trolley wheel to fall off the axle, then falls(11) each part of the brake is a working device and a safety device
Q:Equipment safety of tower crane
Some use units over profit, not pay attention to safety, small horse cart, overloading seriously, tower crane accident is one of the main source of high incidence. Some manufacturers in order to meet the construction requirements of the enterprise, expand sales, to occupy the market, will be independent of height increase, the boom will be lengthened to increase the tower coverage, this is bound to reduce the stability of tower crane, reduce the rated lifting weight, increased insecurity. There are some private and unauthorized modification of the tower crane tower crane in the assembly, this part of the tower crane for a long time in the second-hand purchase price is cheap, not willing to invest in maintenance, and frequent failure, which should arouse our attention, we should seek truth from facts, according to local conditions, to solicit the views of all parties on the basis of the introduction of relevant the supporting policies to solve this problem. By strengthening the safety management of several aspects of tower crane, it can effectively prevent all kinds of accidents in the process of tower crane use, and play a preventive role. Practice shows that as long as the construction enterprises, factories, construction administrative departments, in accordance with the tower crane detection institutions can each link to do, to strengthen the safety management of the tower crane, can effectively control the incidence of major accident of crane.
Q:Tower crane railing height is greater than or equal to meters
1500cm underground enclosure shall not be less than 100com. Thank you
Q:What is the scrap standard of tower crane hook?
The hook shall be scrapped at any time in the following circumstances:Crackle;The wear of the dangerous section is 10% of the original size;The opening ratio is increased by 10% than the original size;The twist of the hook is over 10 degrees;The dangerous section of the hook or the neck of the hook produces plastic deformation;The hook thread is corroded;When the hook bushing is worn at 50% of the original size, the bushing shall be replaced;The mandrel shall be replaced when the hook mandrel is worn at 5% of the original size.
Q:Tower crane four limit, two insurance, two insurance what is that?
Refers to the air switch and the electric leakage protector in the electric tray.
