Overview
The container spreader is a key device used to lift containers. Its main function is to lift from the four corner fittings on the top of the container. The structure of the spreader usually includes a metal structure frame, a twist lock device, a guide claw device, etc. According to different needs, spreaders are divided into many types, such as fixed spreaders, telescopic spreaders and rotating spreaders. Fixed spreaders are mainly for containers of specific sizes, while telescopic spreaders can adapt to containers of different sizes by adjusting the length, such as 20-foot, 40-foot and 45-foot containers. In addition, the rotating spreader can rotate the container during the lifting process, making it easier to place it in a specific direction or in a small space.

The working principle of container spreader mainly relies on its internal mechanical or hydraulic mechanism. For example, the telescopic spreader realizes the telescopic action through the reduction motor drive chain transmission. When the telescopic beam reaches the specified position, the limit switch cuts off the power supply to stop the movement. The rotating spreader completes the rotation by driving the pinion of the reduction motor to drive the slewing bearing. These designs not only improve the flexibility and adaptability of the spreader, but also enhance its operation ability in complex environments.
Features
As the core equipment of modern logistics and port loading and unloading, container spreaders have significant advantages in the field of container handling due to their high efficiency, safety and intelligent design. The following is a detailed description of their main advantages:
High strength and durability
The frame of the spreader is usually made of high-strength steel to ensure that it can withstand and safely handle containers weighing tens of tons. The choice of materials and structural design ensure the stability and durability of the spreader in long-term use.
Precise locking device
This is one of the most core parts of the spreader, responsible for firmly grasping the four corners of the container during the lifting process. The locking device of modern spreaders is precisely designed to remain highly reliable under different environmental conditions and can adapt to different specifications of container sizes to ensure the safety and efficiency of the loading and unloading process.
Intelligent control system
With advanced intelligent control systems, it can achieve precise control of the spreader operation, including automatic identification of container weight, center position and other information. Some high-end models also support remote control and automated operation, greatly improving work efficiency and safety.
Guidance and positioning function
In order to improve operational accuracy and reduce errors, spreaders are usually equipped with guiding devices. These devices help to quickly and accurately align the position of the container, which is particularly important in high-density container yards.
Strong adaptability
Not only limited to standard-sized containers (such as 20 feet and 40 feet), many spreaders can also adapt to special specifications or non-standard-sized containers by adjusting the locking device, increasing the flexibility and scope of application.
Reduce operating costs and achieve high long-term benefits
Optimize hydraulic/electric systems, reduce energy consumption, and reduce long-term use costs. High-efficiency operations can quickly recover investment costs.

Application
Container spreaders are widely used in various fields of modern logistics and cargo handling, mainly including port terminals, railway freight, logistics warehousing, ship transportation, manufacturing and special industries. At port terminals, spreaders cooperate with quay cranes, yard cranes and other equipment to achieve efficient container loading and unloading between ships and yards; in railway freight, they are used for rapid transfer between trains and trucks to improve multimodal transport efficiency; in the logistics warehousing field, automated spreaders are used to optimize container storage and sorting; in ship transportation, corrosion-resistant spreaders are needed to adapt to the marine environment.
