The following is a structured article about the composition of cranes based on the compilation of hot topics on the Internet in the past 10 days and combined with user needs.
What does a crane consist of?
As an important piece of equipment in construction machinery, the crane has a complex structure and diverse functions. This article will analyze the core components of the crane in detail based on the recent hot spots in the field of construction machinery (such as intelligent upgrades, new energy power and other trends).
1. Main structural modules of the crane
| module name | Function description | Technology Development Trends (2024) |
|---|---|---|
| Lifting mechanism | Including hooks, wire ropes, pulleys, etc., responsible for lifting and lowering goods | Intelligent anti-sway system has become a hot topic |
| slewing mechanism | Achieve horizontal rotation of the boom | Increased popularity of electric swing motors |
| luffing mechanism | Control the change of boom elevation angle | Electro-hydraulic proportional control technology upgrade |
| Outrigger system | Ensure operational stability | Automatic leveling system attracts attention |
2. Comparison of power system composition
| Power type | Market share (2024) | Advantages | Representative models |
|---|---|---|---|
| diesel engine | 65% | Powerful and suitable for complex working conditions | Sany STC500 |
| Electric system | 28% | Zero emissions, the first choice for urban construction | Zoomlion ZTC250NE |
| hybrid | 7% | Taking into account environmental protection and battery life | XCMG XCT25PHEV |
3. Recent industry hot technologies
1.Intelligent security system: Many manufacturers have launched AI anti-collision systems to monitor the operating radius in real time through millimeter wave radar.
2.Lightweight design: Using high-strength steel to reduce the crane's dead weight by 15% has become a hot topic at the exhibition.
3.remote control: The application of 5G technology enables some models to achieve precise control from a thousand meters away, and related demonstration videos have recently become popular on social media.
4. Dynamics of key component suppliers
| Parts | Head supplier | technological breakthrough |
|---|---|---|
| Hydraulic system | Rexroth/Hengli Hydraulic | Launched integrated intelligent valve group |
| control panel | B&R/Holisee | Touch screen ratio increased to 80% |
| wire rope | giant rigging | New composite material increases service life by 3 times |
5. Purchasing suggestions (combined with recent user discussion hot spots)
1. FollowLatest announcement from the Ministry of Industry and Information TechnologyModels that meet the National IV emission standards in China
2. It is recommended to choose new energy vehicles for urban construction. Recently, many places have introduced subsidy policies for electric construction machinery.
3. Second-hand market data shows that models equipped with intelligent systems have a 15-20% higher value retention rate.
To sum up, modern cranes are developing in the direction of intelligence and electrification. Its composition not only includes traditional mechanical structure, but also integrates a large number of electronic control systems. It is recommended that users make a choice based on the latest technology trends and their own working conditions when purchasing.
