What is a dock crane
Dock cranes are an indispensable and important equipment in port loading and unloading operations, and are mainly used for loading, unloading and handling of containers, bulk cargoes and other goods. With the rapid development of global trade, the technology and application of dock cranes are also constantly upgrading. This article will combine popular topics and hot content in the past 10 days to introduce the definition, classification, application and related data of dock cranes in detail.
1. Definition of dock crane
Pier crane, also known as port crane, is a large-scale lifting equipment specially used in port terminals. It unloads cargo from the ship to the dock or loads it from the dock to the ship through devices such as robotic arms, hooks or fixtures. The dock crane has the characteristics of high efficiency, stability and safety, and is one of the core equipment of modern port logistics.
2. Classification of dock cranes
Depending on the structure and function, dock cranes can be divided into the following categories:
| type | Features | Application scenarios |
|---|---|---|
| Bridge crane | Steel structure bridge across the wharf, with hooks movable along the bridge | Container terminals, bulk terminals |
| Door crane | Fixed to the dock ground, rotatable and variable width | Bulk loading and unloading, grocery terminal |
| Tire crane | Strong mobility and flexibly mobile | Temporary loading and unloading, small terminals |
| Coast and bridge crane | Designed for containers, high efficiency | Large container terminal |
III. Application of dock crane
Dock cranes are widely used in major ports around the world, especially in container transportation. The following are application cases related to dock cranes in the past 10 days:
1.Automated dock construction: Recently, the fourth phase of Shanghai Yangshan Port automated terminal has become a hot spot. The automated shore and bridge crane it uses has achieved unmanned operation, greatly improving loading and unloading efficiency.
2.Green energy applications: Some ports have begun to try to change the dock crane to electric drive to reduce carbon emissions. For example, Ningbo Port recently announced that it will gradually replace traditional diesel-driven cranes.
3.Intelligent monitoring system: Through the Internet of Things technology, the operating status of the dock crane can be monitored in real time to prevent failures. This technology has been applied in the latest project in Singapore Port.
4. Related data of dock crane
The following are the data related to dock cranes mentioned in the hot topics in the past 10 days:
| Data Items | Value | source |
|---|---|---|
| Global terminal crane market size | About $15 billion | International Port Association |
| Automated shore bridge crane efficiency | 40-50 boxes per hour | Shanghai Yangshan Port |
| Emission reduction effect of electric terminal crane | Reduce carbon emissions by more than 30% | Ningbo Port Report |
| Accuracy of fault warning of intelligent monitoring system | More than 90% | Singapore Port Technical Documentation |
5. Summary
As the core equipment of modern port logistics, the technology and application of dock cranes are constantly innovating. From automation to green energy to intelligent monitoring, the development trend of dock cranes is closely linked to global trade and environmental protection needs. In the future, with further technological breakthroughs, dock cranes will achieve greater improvements in efficiency, safety and environmental protection.
Through the introduction of this article, I believe everyone has a more comprehensive understanding of dock cranes. If you are interested in a certain aspect of dock cranes, you can further pay attention to relevant industry trends and technological progress.
