The national standard requires the instruction of the manufacturer's manual.
Q:What tower cranes are used on the 30 storey house?
but if the building steel structure more parts or building the number of square meters more than 60 thousand square meters, you need to consider QTZ80 or more of the tower crane, because the type of large lifting capacity is big, the work efficiency is high. Hope to be of help to you!
Q:The role of slewing limiter in tower cranes is limited
The function of the rotary limiter is to restrict the large arm to stop at a certain setting. Protect from turning to dangerous range so as to avoid collision and other dangerous accidents!The function of the amplitude limiter is to restrict the car to come out or return somewhere to stop and protect the car from or within certain dangerous range.The hook safety device is to prevent the wire rope from falling out of the big hook, so as to avoid falling and other dangerous events!
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:How to fix the cable on the tower of QTZ125 type tower crane?
segments can be fixed after solving this problem, usually with plastic copper (with insulating layer) and insulator is fixed on the tower body section,
Q:How about the installation and disassembly of the tower cranes?
Authorized by the national security inspection department, the local special operations training school or the technical quality supervision bureau, after the study, assessment, qualification and graduation permit, will give you special operations installation, removal operation certificate.
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:Protective earthing resistance of tower crane
Q:Operation points of tower crane (tower crane)?
Safe use requires the use of tower crane, issued by the state competent authorities shall abide by the rules and regulations, but also comply with the relevant provisions in the manual: the crane working environment temperature is -20~40 degrees Celsius, the maximum working pressure is 205N/m2, when should stop using the winds of more than 6 level; the same construction site to install more than two sets of tower crane when should pay attention to the location of each tower, take the elevation of different operations, in order to avoid the tower crane jib, balance arm collision accidents; safety device of tower crane, luffing and slewing height, mass and moment limiter, the last two more important, if the two is not detected qualified, will be regarded as the unqualified, because it plays a role to ensure the safety and prevent the tilting of the tower crane. As a construction site, the tower crane torque limiter failure or to replace the operating personnel mistakenly believe that daily only hanging 800-1000kg materials, not what the risk, the results in a process of lifting materials, because of the construction site is narrow, hanging by the operator sight blocked, hanging objects hanging on building the steel frame, caused by tower crane shaking, was the occurrence of major accidents, thanks to the ground work riggers promptly notify the operator immediately stop to avoid rollover accident of tower crane appeared.
