Q:What are the requirements for jack up and plus section of jack up tower crane?
Shall conform to:1, tower crane has not reached the standard free height or attachment, not to the standard suspension height;2. The standard section of tower crane jacking must be the size of the original production;3, tower crane jacking work must be carried out by the professional installation team;4 tower crane jacking up, the wind must be less than four.Answer the 1 floor:The height of the self elevating tower crane is built up by other cranes like building blocks.
Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
1. Tower crane consists of three parts: metal structure, working mechanism and electrical system. The three main technical parameters are lifting moment, lifting weight and working speed. Lifting moment refers to the boom as the basic arm length maximum amplitude corresponding to the rated lifting weight of product, product or maximum weight with the corresponding inflection point.
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:When the tower crane is installed in the fertilizer tank,

First of all, it is certainly impossible to install the elevator, because the tower and elevator certificate is not the same
Q:What is the difference between a tower crane QTZ31.5 and a QTZ40?
Lifting moment, arm length, elevation is not the same ah! Specifically, the maximum lifting weight of QTZ315 is 3 tons, the length of the arm is from 38-42 meters, the elevation is 27-28 meters; the maximum QTZ40 is 4 tons; the length of the arm is 42-48 meters; the elevation is 29-32 meters.
Q:What role does the tower crane torque limiter play?
The overload protection of tower crane is protected by two equipment, lifting load limiter and torque limiter. The latter generally in the big arm root 4-5 meters to the front of the large arm, overloading (Chao Liju) work, it is more important, basically, the scope of work is torque limiter plays a protective role. While the former is the weight limiter function in the arm root within 4-5 meters, because the tower crane is a jib type crane, each allowing weight lifting position corresponding to the different (CAB load curve). For example, such as 63KN.M, the big arm root 2 meters lifting, the theory is 23 tons, while the torque limiter is not over, but in fact, the tower crane at early crouched down, so the weight limiter in this work.
