As crucial hubs for international trade, ports and terminals rely on advanced lifting equipment for efficient and safe loading and unloading operations. From traditional fixed lifting gear and electric telescopic lifting gear to modern cranes and stackers, and innovative electro-permanent magnetic lifters, each type of lifting gear plays an irreplaceable role in its respective field. Today, we will review the commonly used types of lifting gear in ports and terminals, with a special focus on Qianhao Magnetic's electro-permanent magnetic lifters and their wide application in handling heavy materials such as steel plates, pipes, and coils at various terminals.

　　 Fixed Lifting Gear: A Classic Choice, Stable and Reliable

　　Fixed lifting gear is one of the most common types of lifting gear in ports and terminals. Its simple structure and affordable price make it a preferred choice for many port lifting accessories. Fixed lifting gear is mainly divided into 20-foot and 40-foot sizes, as well as semi-automatic and fully manual types. Semi-automatic lifting gear relies on its own weight and spring potential energy to rotate the intermediate shaft, driving the pin to lock the container, while fully manual lifting gear requires manual rotation of the pin to open and lock the container. The maintenance of fixed lifting gear is relatively simple, requiring only regular inspection of the wire ropes, making it a classic choice for many ports and terminals.

　　 Electric Telescopic Lifting Gear: Flexible and Efficient, Highly Adaptable

　　Electric telescopic lifting gear is another commonly used port lifting gear. It integrates the functions of various sizes of lifting gear, adapting to different container models through the telescopic movement of the main beam. The power source of electric telescopic lifting gear is mainly electric and electro-hydraulic, with electro-hydraulic being more stable in harsh seaside environments. To improve work efficiency, this type of lifting gear is also equipped with various optional additional functions, such as hydraulic guide plates, tilting devices, rotating mechanisms, and central adjustment mechanisms. Multiple sensors are installed on the electric telescopic lifting gear, linked to the lifting of the crane, improving safety and reducing risks. Although the price and maintenance costs are slightly higher, its multi-functionality and flexibility make it widely used in many high-end ports and terminals.

　　 Cranes and Stackers: Diverse Applications, Meeting Various Needs

　　Cranes are indispensable loading and unloading equipment in ports and terminals. According to their structure and transmission methods, they can be divided into various types, such as bridge cranes, gantry cranes, tower cranes, and telescopic boom cranes. They are mainly used for loading and unloading goods in ports, moving goods from one location to another. Stackers, on the other hand, are mainly used for handling and stacking goods within the yard. Their structure usually consists of a cab, chassis, lifting mechanism, and hydraulic transmission system. Container cranes and gantry cranes are the leaders among port lifting equipment, used for unloading or loading containers from ships and for handling larger and heavier goods.

　　 Electro-Permanent Magnetic Lifters: Innovation Leading the Way, Efficient and Energy-Saving

　　Among numerous lifting gears, electro-permanent magnetic lifters stand out for their efficiency, stability, and energy saving. Utilizing the principle of electro-permanent magnets, electro-permanent magnetic lifters can flexibly handle various lifting needs, easily coping with steel plates of various thicknesses and complex stacking positions. This type of lifting gear not only improves work efficiency and safety but also significantly reduces energy consumption and operating costs.

　　As a leading brand of electro-permanent magnetic lifters, Qianhao Magnetic's products have significant advantages in the port and terminal field. Qianhao electro-permanent magnetic lifters adopt advanced electro-controlled permanent magnet technology, quickly reaching saturation in the magnetized state to provide stable and reliable support for lifting operations. Compared with traditional electromagnetic lifters, electro-permanent magnetic lifters retain their magnetism when the power is off, avoiding safety accidents caused by power outages. This feature ensures that even in unexpected situations, the lifted heavy objects will not suddenly fall, greatly improving operational safety.

　　In addition, Qianhao electro-permanent magnetic lifters are highly energy-efficient. They only consume electricity during the moments of magnetization and demagnetization, and consume almost no electricity during normal operation. This design makes the energy consumption of electro-permanent magnetic lifters far lower than that of traditional electromagnetic lifters. Statistics show that their energy-saving effect can reach over 90%. For enterprises, this not only means a significant reduction in energy costs but also reduces the heat generated by continuous power supply, lowering the working environment temperature and further improving operational efficiency.

　　When loading and unloading steel plates, pipes, and coils at various terminals, Qianhao electro-permanent magnetic lifters demonstrate excellent performance. Their powerful magnetic force can easily adsorb various heavy goods, and the magnetic force is adjustable to meet the lifting needs of goods of different weights and sizes. At the same time, Qianhao electro-permanent magnetic lifters are easy to operate, equipped with wired or wireless remote controllers, allowing workers to remotely control the movement, lifting, and magnetization/demagnetization of the lifting gear, greatly reducing labor intensity.

　　In summary, there are many types of lifting gear in ports and terminals, each with its unique advantages and applicable scenarios. Qianhao Magnetic's electro-permanent magnetic lifters, with their innovative technology and excellent performance, are gradually changing the lifting gear landscape of ports and terminals, becoming an important direction for future lifting gear development. With continuous technological advancements and market expansion, Qianhao Magnetic's electro-permanent magnetic lifters are expected to play an even more important role in the port and terminal field, providing strong support for the smooth operation of international trade.
