Introduction

Since its inception in the mid-20th century, container transportation has rapidly become the core of modern logistics systems due to its advantages of standardization, high efficiency, and low cost. As a bridge connecting containers and transportation vehicles, the performance and quality of container spreader and loading and unloading equipment directly affect the efficiency and safety of the entire logistics chain. With the continuous advancement of technology, these devices have not only become more complex and precise in structure, but have also made significant progress in intelligence and automation.

Classification and characteristics of container spreader

Container spreader is a specialized device used for lifting and transporting containers. Depending on its structure and purpose, it can be divided into various types:

• Universal container spreader: This is the most common type of spreader, suitable for lifting operations on 20 foot and 40 foot standard containers. Its design is simple and its operation is flexible, making it the main lifting tool for ports, docks, and logistics parks.
• Double box spreader: capable of lifting two containers simultaneously, significantly improving loading and unloading efficiency. Suitable for ports and logistics centers with high container throughput, especially in the trend of large-scale container ships, the use of double box spreader is becoming increasingly widespread.
• Rotating lifting appliance: It has the function of rotating, and can adjust the direction of the container during the lifting process. It is suitable for the situation where the site is narrow and the container arrangement is complex, which improves the flexibility and efficiency of the operation.
• Automated spreader: Combined with an automated control system, remote control and intelligent scheduling can be achieved, reducing manual intervention and improving operational accuracy and safety. This is an important direction for the future development of container spreader.

Principles for selecting container spreader

Choosing appropriate container spreader is of great significance for improving operational efficiency, reducing operating costs, and ensuring operational safety. When selecting, the following aspects should be considered:

• Operational requirements: the choice of suitable spreader type and size is based on the volume of work, type of containers, site conditions and other factors. For example, for large ports, double container spreaders or automated spreaders may be more appropriate.
• Technical performance: Pay attention to the technical parameters such as the load-bearing capacity, working speed, and rotation angle of the spreader to ensure that it meets the operational requirements. At the same time, considering the reliability and durability of the spreader, reducing the failure rate and maintenance costs.
• Safety: Safety is the primary condition for selecting spreader. Spreader that meets international standards and has passed safety certification should be selected, and necessary safety devices such as anti decoupling devices and overload protection devices should be equipped.
• Maintenance cost: Consider the maintenance cost of spreader, including parts replacement, regular inspections, repair costs, etc. Choosing a spreader brand that is easy to maintain and has sufficient supply of accessories can reduce long-term operating costs.
• Intelligent level: With the development of automation and intelligent technology, spreader with remote monitoring, fault diagnosis and other functions will be more competitive.

Maintenance of container spreader

Maintenance of container spreader is the key to ensure its long-term stable operation and prolong its service life. The following are common maintenance methods:

• Daily inspection: before and after each operation, the spreader should be fully inspected, including the wear and tear of the wire rope, hook, pulley, bearing and other parts, as well as the operation status of the electrical system and hydraulic system.
• Regular maintenance: according to the use of the spreader, make a detailed maintenance plan, including the replacement of wear parts, cleaning and lubrication, adjusting the gap and so on. Regular professional maintenance is carried out to ensure that the spreader is in the best working condition.
• Troubleshooting: Once the spreader is found to be malfunctioning or abnormal, stop using it immediately and ask professional personnel to diagnose and repair it. Avoid working with disease and prevent the failure from expanding.
• Record management: Establish a perfect maintenance record to record each inspection, maintenance and repair, so as to track the history of the spreader’s use and health condition.
• Training and education: Provide professional training to operators to make them familiar with the structure, performance, operation procedures and emergency disposal methods of spreaders. Improve operators’ safety awareness and operating skills to minimize failures and accidents caused by human factors.

The latest development trend and application practice of loading and unloading equipment

With the continuous progress of logistics technology, container loading and unloading equipment is developing in the direction of automation, intelligence and greening. The following is the latest development trend and application practice of current loading and unloading equipment:

• Automated loading and unloading system: Automated loading and unloading system has become an important means for ports and logistics centers to improve efficiency and reduce costs. Through the integration of automated spreaders, driverless vehicles, intelligent scheduling systems, etc., the unmanned and intelligent loading and unloading operations are realized. For example, the Port of Rotterdam, Shanghai Port and other world-renowned ports have applied automated loading and unloading systems on a large scale, significantly improving operational efficiency.
• Digital management platform: With the help of Internet of Things, big data, cloud computing and other technologies, a digital management platform is established to realize the functions of remote monitoring, data analysis and failure warning of loading and unloading equipment. Through data analysis, it optimizes the operation process and improves the efficiency of resource utilization.
• Green energy-saving technology: In the face of the global energy crisis and environmental protection pressure, green energy-saving technology has become an important direction for the development of loading and unloading equipment. Adoption of energy efficient drive system, application of renewable energy, implementation of carbon emission management and other measures to reduce the energy consumption and emissions of the equipment.
• Multi-functional integration technology: With the diversification of logistics needs, loading and unloading equipment is developing in the direction of multi-functionality and integration. For example, multi-functional loading and unloading equipment integrating lifting, carrying and stacking can flexibly cope with different operational scenarios and improve the utilization rate and operational efficiency of the equipment.
• Human-computer interaction technology: In order to improve the safety and convenience of operation, human-computer interaction technology has been widely used. Through the touch screen, voice control and other means, it realizes the convenient interaction between operators and equipment, and improves the operation precision and efficiency.
