Descriptions of our tower crane:

Our Tower Crane is characterized by horizontal jib frame, trolley travel, slewing self-climbing, novel structure and reliable running. All accessories are adopted from home famous brands and electrical components from international famous brands. “Quality First” is not just a slogan, which has already deeply rooted in our soul, besides we will also make all your purchases in unlimited satisfaction with our star-rated after-sales service.

Advantage of our tower crane:

1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.

2, suitable for the group of tower cross homework.

3, boom stability is good, combination amplitude range.

4, suitable for height have special requirements occasions construction.

5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

Q:Who is responsible for the construction of the pile foundation of the tower crane?
In fact, in the long run, in a word, what the construction site is finally all party a pay, just clearing the count.
Q:How high the tower crane needs to be installed with the wall pole. How is it stipulated in the national standard?
Beyond the maximum independent height of the tower crane design, a wall attaching rod shall be installed
Q:What kind of personnel should be installed for the tower crane installation and disassembly?
2, with special construction operation qualification certificate of construction, lifting machinery, installation, demolition workers, lifting signal workers, lifting drivers, cable operators and other special operations personnel.And an electrician.
Q:What is the difference between a jack up tower crane and a fixed tower crane?
The fixed tower crane means lifting the foundation of the tower body on the foundation or structure through the connecting piece.
Q:How to distinguish self lifting tower crane with counterweight and lifting tower crane without counterweight
2 the tower crane without counterweight is mainly the city fast loading tower crane. It is characterized by the absence of balance arm, and it is impossible to have counterweightThe layman can not tell the can see the appearance, there are long steel structure before and after the weight of the tower body, and no weight of the tower body with only one steel structure (i.e. jib crane, structure)
Q:What are the main parameters of a tower crane?
The main parameters of tower crane are:1, rated lifting torque. Lifting torque is the most comprehensive reflection of tower crane performance because the lifting torque itself is the product of the two parameters of magnitude and weight. The lifting moment is the product of the lifting and the amplitude.2, lifting range. The lifting range is also referred to as the radius of gyration or the radius of work. It refers to the horizontal distance from the center of the tower crane to the center line of the hook. The range contains two parameters of maximum amplitude and minimum amplitude.3. Rated lifting capacity. Rated lifting capacity refers to the weight of a crane under different working conditions. In general, the lifting capacity and the maximum lifting weight are marked in the main performance parameters, and the rated weights of other states are determined by their characteristic curves.4, maximum lifting height. For boom type tower cranes, the maximum lifting height according to the boom of the elevation and the tower height is different.
Q:What are the safety devices in a tower crane?
(1) lift height limit position limiterFor cranes with variable boom angles, the lifting motion must be stopped immediately when the top of the lifting device rises 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 lift limiter;When the 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.(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.(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.
Q:How much more than m of tower crane jib winch point height should be equipped with anemometer
According to the regulations of JGJ196-2010 for the safety and safety of installation, use and disassembly of tower cranes for construction purposes:
Q:What does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
Q:What type of tower crane does not include tower crane in variable amplitude mode?
Mobile tower crane: a tower crane with running device and can walk.
