What crane to use for lifting steel: Analysis of hot topics on the Internet and equipment selection guide
Recently, the safety and equipment selection of steel hoisting operations have become hot topics in the engineering field. This article combines the hot content of the entire network in the past 10 days to provide you with a detailed analysis of the key points of crane selection for lifting steel, and attaches a structured data comparison.
1. Recent hot topics in the steel hoisting industry
| topic | heat index | Main discussion points |
|---|---|---|
| Ultra-high strength steel hoisting accident | 8.5/10 | Safety regulations and equipment load limits |
| New energy crane applications | 7.2/10 | Environmental performance of electric cranes |
| Intelligent lifting system | 6.8/10 | Application of Internet of Things Technology in Hoisting |
| Steel terminal loading and unloading efficiency | 6.5/10 | Port special crane selection |
2. Comparison of commonly used crane types for steel hoisting
| Device type | Applicable scenarios | Maximum lifting capacity | Advantages | limitations |
|---|---|---|---|---|
| truck crane | Short distance transfer at construction site | 300 tons | Maneuverable and flexible | Working radius is limited |
| tower crane | high-rise building construction | 60 tons | Wide coverage | Long installation period |
| Gantry crane | Steel warehousing operations | 1000 tons | Strong load-bearing capacity | Use in fixed places |
| crawler crane | Heavy steel structure installation | 4000 tons | Super stability | Transfer speed is slow |
3. Key factors in selecting steel hoisting equipment
1.Steel properties: Different specifications of steel have special requirements for lifting. For example, H-shaped steel requires special lifting beams, and steel plates require electromagnetic chucks.
2.working environment: Consider height restrictions for indoor operations, and pay attention to the impact of wind load outdoors. Recent hot cases show that a lifting accident occurred at a construction site due to neglect of wind speed.
3.economic efficiency: Choose to purchase or lease according to the project cycle. Although the initial cost of new energy equipment is high, it is more environmentally friendly and energy-saving in the long term.
4. Latest industry standards for safe operation
| Canonical items | Specific requirements | Update date |
|---|---|---|
| GB/T 3811-2023 | Rated lifting capacity dynamic test standard | 2023.12 |
| JGJ 276-2019 | Safety Technical Regulations for Steel Structure Hoisting | 2019.11 |
| ISO 12480-1:2022 | Crane operation and management specifications | 2022.06 |
5. Future technology development trends
1.Intelligent lifting system: Real-time monitoring of the steel center of gravity position through sensors and automatic adjustment of the lifting angle.
2.Lightweight design: Crane arms made of carbon fiber materials can increase operating efficiency by 20% and have become a hot topic at recent industry exhibitions.
3.Remote control technology: Remote precise control supported by 5G network, especially suitable for operations in hazardous environments.
Summary: Selecting steel lifting equipment requires comprehensive consideration of weight specifications, operating environment and economic benefits. It is recommended to give priority to equipment that meets the latest safety standards and has intelligent monitoring functions, and pay attention to the application progress of new energy technology in the field of hoisting.
