What does crane mean
Crane is a heavy machinery and equipment widely used in construction, logistics, rescue and other fields, and is mainly used to carry heavy objects vertically or horizontally. With the recent changes in social hot topics, topics related to cranes have frequently appeared in the public eye. This article will analyze the definition, classification and application scenarios of cranes based on popular topics across the network for the past 10 days, and display its social attention through structured data.
1. Definition and core functions of cranes
Crane is an engineering equipment that lifts and moves heavy objects through hydraulic or mechanical transmission systems. It is usually composed of a chassis, boom, lifting mechanism, etc. Its core functions include:
| Function Type | Specific description |
|---|---|
| Vertical lifting | Vertical lifting and lowering of heavy objects through wire ropes and pulley sets |
| Move horizontally | Position transfer is completed by rotating the chassis or track system |
| Precisely placed | Equipped with a micro-movement control system to achieve millimeter-level positioning |
2. Crane application in recent hot events
According to the network-wide data monitoring, crane-related hot spots have been mainly concentrated in the following areas in the past 10 days:
| date | Hot events | Associated crane type |
|---|---|---|
| 2023-11-15 | Fire rescue in a city | Ladder fire truck |
| 2023-11-18 | Steel box girder hoisting of cross-sea bridge | Floating crane |
| 2023-11-20 | New energy wind turbine installation | All-ground crane |
3. Main classification and technical parameters of cranes
Currently, mainstream cranes can be divided into the following five categories, and their technical characteristics are significantly compared:
| type | Maximum lifting capacity | Typical application scenarios | Recent hot search index |
|---|---|---|---|
| Car crane | 20-1200 tons | Urban infrastructure | 85,000 |
| Tower crane | 1-100 tons | High-rise buildings | 62,000 |
| Track crane | 50-4000 tons | Heavy Industry | 58,000 |
| Gantry crane | 5-50 tons | Port logistics | 34,000 |
4. Analysis of social attention data
Data collected by the public opinion monitoring system for the past 10 days shows that the public's focus on cranes is as follows:
| Focus on dimensions | Discussion percentage | Year-on-year changes |
|---|---|---|
| Safety accidents | 42% | +15% |
| Technological innovation | 28% | +7% |
| Vocational Training | 18% | -3% |
| Environmental protection standards | 12% | +22% |
5. Development trend of the crane industry
Based on recent hot topics, it can be seen that crane technology is developing towards intelligence and greenness. A brand's latest pure electric crane has received more than 100,000 reposts on social media, and its zero emission characteristics have sparked widespread discussion. At the same time, the application of IoT technology has made remote monitoring, automatic collision prevention and other new standards in the industry.
It is worth noting that the crane overturning accident occurred in a certain place on November 19 once again attracted public attention to operating specifications. Experts suggest that operator training and assessment should be strengthened, and the application of safety devices such as intelligent limiting systems should be promoted.
The data statistics cycle of this article is from November 15 to November 25, 2023, and the data sources include mainstream social media platforms, news websites and professional forums. Through analysis, it can be seen that as a key equipment for modern engineering construction, cranes have always maintained a high correlation with social security.
