Q:National standards for tower cranes
Tower crane GB/T5031 - 2008 has been implemented since February 1, 2009. In accordance with the new standards promulgated, chief editor -- China Academy of Building Research Institute of building mechanization of Langfang, Beijing and Hebei respectively in Hangzhou, Nanning held the new standards xuanguan. Luo Wenlong, director of the standard editor and vice president of Li Shoulin, explained the new standards comprehensively. The new standards are quite different from the previous standards, adding a lot of security related content, mainly embodied in the following 3 aspects: 1) the principle of different. Previously considered issues mainly consider the domestic tower crane industry technology status, appropriately reflect the advanced nature, and now is the requirements and international benchmarking, consider safety. 2) different forms of organization. The standard used in scientific research institutes, universities, factory assistant; the preparation unit including Research Institute, and the host plant, supporting enterprises, universities, inspection unit, there are relatively large units on behalf of (rental business), etc..
Q:Tower crane installation, wind speed is greater than 12m/s, wind should stop operation,
This is not on the project department climbed to tower crane to measure wind speed, regardless of height, is listening to the local meteorological station forecast, more than five winds, should stop working.
Q:Tower crane and construction hoist service life? What are the norms and standards? How to detect?
The tower crane service, QTZ40 state (including 40) the following ten years, more than QTZ63, the age of fifteen years, the construction elevator used for ten years; but specific to various provinces and cities are different, such as Jiangsu Province, the 40 tower crane can be used 8-10 years, QTZ63 tower crane used for 15 years, 8 years of construction hoist. Of course, we should not blindly look at the provisions, tower cranes and the use of strength sometimes determines the life of it!
Q:What are the types of common tower cranes?
Tower crane, tower crane. Tower crane according to its different types, there are the following classification methods.(1) according to the structural typeThe fixed tower crane by connecting a fixed tower in the foundation or structure, tower crane lifting operation.Mobile tower crane: a tower crane with running device and can walk. According to the running device, it can be divided into rail type, tyre type and caterpillar type.
Q:When the tower crane is installed in the fertilizer tank,
Pouring foundation does not increase the foundation safety first
Q:How many meters is the tower crane installed on the edge of the deep foundation pit?
Tower crane foundation, if set up in the foundation pit, the foundation is to pile other, general tower crane is to support the wall.Therefore, how far away from the foundation pit is determined by the distance from the retaining wall.According to the industry standard "technical specification for concrete foundation of tower crane tower crane foundation installation" (JGJ/T187-2009), the installation of tower crane foundation concrete should reach more than 80% of design strength, the tower crane foundation concrete design strength should reach 100%.
Q:How many tons are tower cranes QTZ125?
Nominal lifting torque KN • m 1250Rated lifting torque KN • m 1300Maximum lifting weight T 8Operating range M 3~60Maximum rated lifting weight t 1.5Maximum lifting speed m/min 80The lowest steady decline speed of m/min is less than or equal to 7Lifting performance two rate lifting speed m/min 80405.6Lifting weight t 248Four magnification lifting speed m/min 40202.8Lifting weight t 488Variable speed m/min 52/26/8Slew speed r/min 0.63Lifting height independent type M 50Attached m 170Design weight t 42.7 (stand height)Counterweight t 21.2The working environment temperature is Co -20 to +40Maximum working wind speed is m/s 20The maximum wind speed at ceiling is m/s 13
Q:Can the attached arm of the tower crane be welded?
The attached arm of a tower crane can not be welded and can only be bolted.Adhesion calculation of tower craneTower crane attachment (anchor) device structure, internal force and installation requirements in the use of narrative instructions so in the tower crane installation and use, the use of units can be executed according to the requirements, do not need to calculate, only when the tower crane installation position to the building from the over manual provisions, to increase attached rod (Zhi Chenggan) two, spacing or attached rod connected with a building when changing to attached calculation.
Q:About tower crane torque limiter with 4 limit switches, each play a role, thank you
Hook top point control: when the hook to the high limit, limit action, do not continue to hook!Overload control: when the weight exceeds the overload point or amplitude exceeds the maximum amplitude or the loading rate is more than 105% when the output control, prohibit the hook lifting action and prohibit car distance to allow the car to increase the amplitude, amplitude can be damped near.
Q:When the tower crane foundation is found, what should be discontinued?
The settlement, inclination and cracking of tower crane foundation can affect the stability of tower crane and should be stopped
