Anonymous users2024-02-10Tower crane QTZ: stands for self-elevating tower crane.
50 indicates the length of the boom, 50 meters;
5013 indicates that the maximum lifting capacity at 50 meters is tons.
There are two main parameters expressed by the tower crane model: one is the rated lifting moment, and the other is the maximum arm length and arm end lifting weight. Introduction to the typical compilation method: the standard stipulates the numbering method.
According to ZBJO4008, China's tower crane model composition is: class code + form + characteristic code + main parameter code.
Class: Q - (from).
Group: t – (tower).
Type: upper ** ascending Z - (self).
Fixed G - (solid).
Crawling p - (climbing).
The next ** ascending type S (liter).
The main parameter is the nominal lifting moment.
Examples of tags are as follows:
Nominal lifting moment 600knm fixed tower crane: QTG600
Weighing lifting moment 1000knm self-elevating tower crane: QTZ1000
Some tower cranes still take TM as the unit of measurement of crane torque, then the above three tower crane models are expressed as QTG60 and QTZ100 respectively.
The safety distance between the rear arm of the tower crane and the adjacent building is not less than 50cm. The safety distance between the tower crane and the power transmission line meets the requirements.

Anonymous users2024-02-08It is the customary name of the tower crane industry to distinguish the size of the tower crane according to the lifting moment, which refers to the tower crane with a lifting moment of 40 tons, 63 tons and 80 tons.

Anonymous users2024-02-07The general category of specifications and models is collectively referred to as children, young people, and old people.
The tower of QTZ40 refers to the tower crane with the original configuration boom greater than 40m and less than 50m; QTZ63 means that the boom is greater than 50m and less than 60m, QTZ80 is greater than 60m and less than 70m, and so on.

Anonymous users2024-02-05What does tower crane TQ60 80 mean.
Dear, hello, I am glad to answer for you, what does tower crane TQ60 80 mean Answer: The main technical performance of the tower crane TQ60 80 type is a rail walking, slewing, variable tower height (non-self-elevating) tower crane. The tower crane model TQ60 80 refers to the ultimate working radius of the tower crane is meters.
The tower crane is a 60-meter 80-meter boom reinforced all-round crane. Q means all-round and Y is hydraulic. QY is a model of the truck crane series**.
QAY is an all-terrain crane series. QUY is a crawler crane series. 25b, 25 tons of second-generation products.
25k, which is a leading product. 25e, which is an economical product. The latter word is actually only an X generation product.
But some small Wu Ran manufacturers are blind. Like the brocade weight F-type, the noisy imitation code is that the arm stem has 60 meters, 80 is 80 meters, and the arm stem 80 tower crane is a cavity collision virtual tower.

5w represents the low-temperature fluidity of the oil, the lower the value, the better the flow, 40 indicates the viscosity of the oil after the normal operation of the engine, and the higher the value, the higher the viscosity. >>>More
The opening and closing parts of the ZA40H gate valve are the gate plate, the direction of movement of the gate plate is perpendicular to the fluid direction, and the gate valve can only be fully opened and closed, and can not be adjusted and throttled. The ram has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces forming a wedge, and the wedge angle varies with the valve parameters, usually 50, and 2°52 when the medium temperature is not high. The gate plate of the wedge gate valve can be made into a whole, which is called a rigid gate; It can also be made into a ram that can produce a slight amount of deformation to improve its manufacturability and make up for the deviation of the sealing surface angle in the processing process, which is called the elastic ram.
