What is the best tonnage of Yangtze River crane? Hot topics and data analysis across the entire network
Recently, the topic of the selection of tonnage of Yangtze River cranes has sparked widespread discussion in the field of engineering machinery. In combination with the hot content of the entire network for the past 10 days, we have compiled relevant data and industry perspectives to help users scientifically choose crane tonnage suitable for operations in the Yangtze River Basin.
1. Analysis of crane operation environment in the Yangtze River Basin
According to the latest data from the Ministry of Water Resources, there are significant differences in navigation conditions and operating requirements in different sections of the main stream of the Yangtze River:
| Section | Average water depth | Bridge height limit | Common Project Types |
|---|---|---|---|
| Upstream (Yichang and above) | 4-8 meters | 15-25 meters | Hydropower station maintenance |
| Middle Tour (Yichang-Hukou) | 6-10 meters | 20-30 meters | Bridge construction |
| Downstream (below Hukou) | 10-15 meters | 30-50 meters | Port construction |
2. Comparison of performance of mainstream tonnage cranes
By analyzing the data of the project bidding platform, it was found that the three most commonly used tonnage cranes for projects along the Yangtze River:
| tonnage | Typical Model | Maximum arm length | Monthly rent (10,000 yuan) | Applicable scenarios |
|---|---|---|---|---|
| 200 tons | XCA200 | 78 meters | 12-15 | Medium-sized bridge repair |
| 400 tons | QAY400 | 96 meters | 25-30 | Port equipment installation |
| 800 tons | ZTC800 | 120 meters | 45-60 | Construction of large hydropower stations |
3. Golden Rules for Choosing Tonnage
Combined with interviews from multiple industry experts, the three major principles for selecting Yangtze River cranes are summarized:
1.The operating radius determines the tonnage: Calculate the maximum lifting radius based on the engineering drawings, and usually choose a tonnage margin of 20% higher than the theoretical requirement.
2.Economic balance: The 200-ton equipment has the highest utilization rate (accounting for 62% of statistical projects), but the use of 800-ton equipment can shorten the construction period by 30%.
3.Passing requirements: Special attention should be paid to the height limit of bridges in each section of the Yangtze River. Some 800-ton equipment needs to be disassembled and transported and assembled on site.
4. References to popular engineering cases in 2023
| Project name | Where is the river section | Tonnage | Work difficulties |
|---|---|---|---|
| Baihetan Power Transmission and Transformation Project | Upstream | 650 tons | Canyon Wind Field Impact |
| Wuhan Yangtze River Second Bridge Repair | Middle Tour | 400 tons x 2 units | Navigation coordination |
| Nantong Port Container Terminal | Downstream | 800 tons | Tide job window |
5. Industry trend forecast
According to Baidu Index, the search volume of "Yangtze River Crane" has increased by 37% in the past 10 days, reflecting three major trends:
1.Modular design is popular: The number of consulting equipment for 600-800 tons that can be transported separately increased by 50% year-on-year
2.Green power rises: New energy cranes have reached 18% of the market share in the Jiang section with strict environmental protection requirements
3.Intelligent hoisting system: The rental premium for models equipped with GPS positioning and automatic balancing systems is 15-20%
Overall, the best tonnage selection of Yangtze River cranes needs to be combined with specific engineering needs, budget restrictions and environmental characteristics. It is recommended to give priority to 400-ton all-pave cranes as a general solution, which has the best adaptability to most Yangtze River engineering projects.
