Q:Type and specification of tower crane,
Big Han tower QTZ63 series mainly produces 5010, 5013 and 55105010 arm length 50 meters, arm tip bearing 1 tons, the basic height of 30 meters, standard section specifications: 16*2.5, 5013 arm long 50 meters, arm tip bearing 1.3 tons, basic
Q:Construction tower crane operator certificate expires, how to verify?
Chongqing "construction crane operator qualification certificate", the need for training after the exam this year, Yubei District has organized a meeting, other areas will organize can ask the competent department, the Department in charge of the Certification Committee is.The following is a notice of the Yubei District organizing examination for your reference:Notice of Chongqing Yubei District construction post training center on training courses for construction lifting machinery operatorsAll construction enterprises, mechanized companies, tower crane leasing companies:In order to strengthen our district housing construction sites and municipal engineering site crane operations personnel management, improve personnel quality, prevent and reduce accidents, according to the State Quality Inspection Administration, the Ministry of construction and the Municipal Construction Committee of the spirit of the relevant documents and regulations. After the study, we decided to hold a training course for construction machinery operators, and hereby notify the relevant matters as follows:I. training objects and registration requirementsWhere the construction enterprises in our district and the relevant units engaged in or engaged in the work, at least 18 years of age, women are not more than 55 years of age, male, no more than 60 years of age, junior high school education, good health.
Q:[tower crane] and [tower crane] what is the difference between, how to distinguish?
There are many nicknames for tower cranesTower Crane Tower Crane Tower
Q:The earthing resistance of tower crane shall not be greater than that of the tower crane
Lightning protection grounding is less than 10, transformer grounding is less than 4, special equipment requirements is less than 1
Q:What are the lifting moment requirements for tower cranes?
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:Can the tower crane personnel install the construction elevator?
First of all, it is certainly impossible to install the elevator, because the tower and elevator certificate is not the same
Q:Brief introduction of ten no hanging criterion for tower crane operation
4, buried objects do not pull the crane; 5, cable-stayed holding objects not hanging 6, the slings and objects; rickety bundle does not meet the safety requirements to crane; 7, vehicle weight hanging directly processed when not hanging;
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.
Q:Operation points of tower crane (tower crane)?
Slewing bearing: tower crane is one of the most critical components, mainly to bear overturning moment and vertical load. After the failure, the demolition and replacement is extremely difficult, loss of large, so you have to check carefully to do maintenance, each 200H must be a senior grease lubrication from the rotary bearing surface, until now exudation. Slewing bearing adopts high strength bolt connection, if the pretension is not enough, or long-term operation, do not check, not fastening, will cause loose. If the individual bolts loose, will cause the remaining bolts overload, the consequences will be disastrous. The luffing mechanism only moves horizontally, the load is light and the line speed is not high, so it should be easy to master and operate. However, the amplitude involves the change of the lifting torque, and if there is no stopping in time, there will be the possibility of over torque. Therefore, the main requirement of variable amplitude operation is stationary parking and accurate positioning. The tower crane is of great height and the hanger is hung longer, so it is easy to swing the hanger when it is running. This is an objective phenomenon. What is called stabilization hook operation is how to make the swinging hook stop quickly, or how to make the hook move with the movement of the crane as soon as possible, and minimize the operation of the swing. The operation of stabilization hook is the skill that the driver should master.
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.
