What does tower crane QTZ mean?
In the construction industry, tower crane is a common type of heavy machinery equipment, and the abbreviation "QTZ" often appears in the model of the tower crane. Many people are confused by this abbreviation and don't know what it exactly means. This article will explain the meaning of "QTZ" in detail, and attach the hot topics and hot content on the Internet in the past 10 days to help readers better understand this term and its related background.
1. The meaning of QTZ
"QTZ" is a common abbreviation for tower crane models, and its specific meaning is as follows:
| letter | meaning |
|---|---|
| Q | The first letter of the pinyin of "lifting" represents the lifting function of the tower crane. |
| T | The first letter of the pinyin of "ta" represents the tower structure. |
| Z | The pinyin initials of "self-raising" represent the self-raising function of the tower crane. |
Therefore, "QTZ" as a whole means "self-elevating tower crane", which is one of the naming rules for Chinese tower crane models. This type of tower crane usually has a self-raising function and can rise on its own as the height of the building increases. It is widely used in the construction of high-rise buildings.
2. Common models of tower crane QTZ
The model number of the tower crane QTZ usually consists of letters and numbers. The number part indicates the maximum lifting capacity and arm length of the tower crane. The following are several common QTZ models and their parameters:
| model | Maximum lifting capacity (tons) | Arm length (meters) |
|---|---|---|
| QTZ40 | 4 | 40 |
| QTZ63 | 6 | 50 |
| QTZ80 | 8 | 56 |
These types of tower cranes are very common on construction sites, and their selection is usually based on the specific needs of the project.
