Product Description:

QTZ125 tower crane is hoisting and conveying machinery which is designed by Shandong Fuyou Co., Ltd. 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 and has excellent performance.

The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the effective amplitude of 50m and the maximum lifting moment of 438kN•m. The tower crane has the lifting height of 29m and the adhesion lifting height of 120m (2 magnification) during independent use.

All the speed indexes of the crane meet or surpass national standards.
The crane has the total installed capacity of 24.9kW, 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 medium-small 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:What are the safety devices for the horizontal arm self lifting tower cranes?
(1) the lift height limit position limiter must be able to stop lifting motion immediately when the lifting device is raised to the 8OOmm at the lower end of the boom. For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately. (2) lifting moment limiter and maximum weight limiter; when lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped. If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value. When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.
Q:Tower crane 10-5-20 is 6T, and 10-5-21 is 8T. What do you mean by tons?
6T/8T refers to the maximum lifting capacity of a tower crane. It doesn't matter what 10-5-20 has to do with it. Maybe your list of numbers is serial number.
Q:How often should the crane be inspected regularly?
Lifting machines are inspected regularly every two years, and explosion-proof lifting machines shall be inspected regularly every year. Must have the corresponding inspection qualification inspection.
Q:How many tons of tower crane QTZ80A lifting?
Lifting torque = mass * radius of gyration (amplitude). That is to say, the bigger the weight is small.
Q:What tower cranes are used on the 30 storey house?
The 30 storey building on the height of about 100 meters to 120 meters, plus 2 to 3 layers of basement, the tower crane must set the height of 110 meters to 140 meters, if the single building is less than 60 thousand square meters of building square meters, as the total number of square meters, using a two QTZ63 type tower crane is enough,
Q:What are the safety devices for tower cranes?
(3) the lifting height limiter, lifting height limiter is used to restrict access to the hook jib head or trolley before, or is dropped to the lowest point (ground or below ground Ruoganmi) before the lifting mechanism of automatic power-off and stop working, to avoid lifting hook over hoisting device touch the boom and the bad.(4) the amplitude limiting device is used to limit the boom does not exceed the limit position in the pitch. An alarm is sounded when the lifting pitch reaches a certain limit, and the power is automatically cut off when the limit position is reached.(5) stroke limiter of car stroke limiter: a trolley type jib head and root, to cut off the circuit car traction mechanism, prevent car offside. Cart travel limiter: used to prevent the crane from derailing.
Q:When the tower crane is installed in the fertilizer tank,
There is no standard in the tower crane foundation and building foundation, there is no such provisions.In fact, you can do whatever you can. The only factor that can be said is the Design Institute, to see if they agree.Design Institute to consider this problem, generally disagree, you let the two based on the surface flat, because there is a stress concentration problems. It's like a pebble under your mattress. So, in general they will demand based on the surface in the construction of tower crane foundation floor, the middle 30-50cm gap with soil pad.Of course, no matter which of these two methods you have to use the back belt to enclose the tower crane foundation.
Q:What kind of bodies are tower cranes made of?
Tower crane is composed of three parts: working mechanism, metal structure and power unit, and control system. The composition and function of the three parts are outlined below.
Q:What is the scope of the installation and disassembly of self lifting tower cranes and the applicable range of the cost and the off-site transportation cost?
The installation and disassembly of the existing self rated tower crane, the first cost and the off-site transportation cost quota are divided by the lifting moment 1000kNm and 2000kNm of the jack up tower crane.
Q:Where can I get the tower crane manufacturing permit?
Zhengzhou China enterprise management consulting company, oh, my uncle company for tower crane manufacturing license is to find them, they are not only a team of professional, and service is very thoughtful, efficient.
