Product Description:

QTZ80(5513) 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:Tower crane 4 how to change the rate of 2 magnification, how to change, say detailed points
At this point, the rope will be turned into 2 fold!Some manufacturers produce pulley, also need to be in the car, and then the magnification pulley with pin shaft fixed in the car!
Q:About tower crane torque limiter with 4 limit switches, each play a role, thank you
The maximum amplitude control: when the weight exceeds or prohibit increase load rate of more than 105% or greater than the maximum amplitude (amplitude limit) output control, allowing the car to be near range by car distance to increase amplitude is prohibited.Minimum range control: when the amplitude is less than the minimum amplitude (amplitude lower limit), the output control allows the car to move to a distant range, i.e., to increase
Q:Tower crane body standard section connection bolt screw upward or downward, why?.
Usually it is worn from top to bottom, so that the nut is loose and the bolt will not fall directly
Q:What is the standard weight of a tower crane for 1.6*1.6*3 and 1.6*1.6*5m? Kg?
The standard weight of tower cranes for 1.6*1.6*3 and 1.6*1.6*5m is 500KG
Q:Can the tower crane personnel install the construction elevator?
Although it belongs to the construction of special operations, but the operation of different categories, tower crane demolition workers according to the requirements can not install the elevator!
Q:Is it difficult to test tower cranes?
A tower crane installation scheme, 1, compilation basis, project overview, working environment, 2 workers and 3 endurance calculation and installation equipment for 4, installation procedures, methods and requirements for 5, commissioning record 6, two safety technical measures, safety technical disclosure, three installation foundation concrete test report of four, the tower crane installation and acceptance of table five, safety supervision station issued a permit for six, seven, demolition demolition project safety technical clarificaiton tower crane installation scheme project name: preparation: position (title): Approval: job (title): the construction unit: tower crane installation demolition project, the preparatory work before construction: 1. The tower crane installation position, according to the effective range of the construction requirements, site conditions and the role of tower crane, convenient installation and disassembly, the tower crane configuration in 17 axis to 18 Between the axis, away from the outer wall of 5 meters, with 11 standard section. 2, the basis of the principle, the use of concrete foundation, strictly according to random basis drawing. 3, the examination of concrete pressure report, tower foundation has been completed by design and construction, the safety group acceptance, the basic test block delivery, after the test pressure qualified, must be installed. 4. The installation site is level and the channel is repaired. 5, transport parts admission

Q:Is tower crane a tower crane?
It is tower crane, tower crane, commonly known as tower crane, tower crane --- tower crane. Ha ha, hope to adopt.
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:What windproof devices should be set up for crane work?
2. torque limiterTorque limiter is an integrated safety protection device for jib cranes.We know that an arm crane represents the load condition from the moment of gravity. The load moment value is made up of product weight, amplitude decision, amplitude value is determined by the product, the boom of the crane arm length and angle cosine so that the crane is overloaded, in fact are the weight, arm length and arm angle limit, while also considering the working conditions and other parameters as well as constraints effect of control is more complex.At present, the widely used microcomputer controlled torque limiter can synthesize various situations and solve this problem better. The torque limiter consists of a load detector, an arm length detector, an angle detector, a work condition selector, and a microcomputer. When the crane to enter the working state, the computer will detect the signal input parameters of the actual working state, after operation, amplifying and processing, and advance into the rated load moment value, and at the same time in the display to display the corresponding actual values. When the actual value reaches the rated value of 90%, it will issue a warning signal when the actual value exceeds the rated load when the alarm signal, at the same time the crane to stop dangerous direction (lifting, boom, arm and rotary movements continue to drop).
