The container spreader refers to a special spreader for loading and unloading containers. It is connected with the top corner fittings of the container through the twist locks at the four corners of the end beam. The driver controls the opening and closing of the twist locks to carry out container loading and unloading operations.
The telescopic spreader drives the telescopic chain or cylinder through hydraulic transmission, so that the spreader can automatically expand and contract to change the length of the spreader, so as to adapt to the loading and unloading of containers of different specifications. Although the telescopic spreader has a large weight, it is easy to adjust the length, flexible operation, strong versatility, and high production efficiency. The electro-hydraulic telescopic spreader is a new type of telescopic container spreader, which can lift various containers such as ISO20’40’45’. The electric translation mechanism can be installed according to the user’s needs, which can realize the translation operation in the direction of the cart and enhance the operability of the spreader.

The telescopic spreader consists of two parts: a fixed frame and a telescopic beam. The telescopic beam is telescopically driven by a telescopic drive mechanism, which can adapt to containers of different specifications. The rotation of the spreader and spreader is generally driven by hydraulic pressure (now a small number of spreaders are driven by pure electric motors), which is controlled by the driver in the crane’s cab. Since multiple sensors are installed on the spreader and the interlocking device of the crane is lifted, the safety of lifting containers can be greatly improved, and various types of risks can be reduced. In order to improve efficiency and meet the lifting requirements of different cranes, manufacturers have installed various mechanisms, such as hydraulic guides, tilting devices, rotating mechanisms, etc. This makes telescopic spreaders more and more complex and more functions.
Telescopic spreaders are suitable for professional container terminals, storage yards and other occasions where various types of containers are often hoisted. Therefore, telescopic spreaders are currently the most widely used spreaders in large-scale port container terminals. This type of spreader has a complicated structure and a relatively large weight, about 8-10t; maintenance is also more complicated, and generally requires professionals to perform maintenance, and the maintenance cycle is also very long.
