Product Description Semi-automatic spreaders rely on a mechanical structure and a small amount of electrical control to complete the lifting task. The main mode of operation is to grasp the object automatically by the gripping device (e.g. hook, clip, fork, etc.) at the lower end of the spreader, and the position or angle can be adjusted automatically during the lifting process. When the gripping device comes into contact with the object, the spreader is automatically locked by gravity or leverage to ensure that the object will not fall off during the lifting process. After completing the lifting, the operator can release the locking manually or mechanically in order to unload the object.A semi-automatic spreader consists of several key components to ensure its effectiveness in various application scenarios. Firstly, there is the main frame, which is usually made of high-strength steel and has a very high load-bearing capacity to support the spreader under heavy-duty conditions. Next is the gripping device, which is the core part of the spreader. Depending on the work requirements, the gripping device can be designed as a hook, a clamp or a fork-type structure. For example, an auto-locking hook can automatically lock the object when it is lifted to prevent it from slipping, while an adjustable clamp is suitable for objects of different shapes and sizes. Next comes the transmission system. Some semi-automatic spreaders are equipped with a mechanical or hydraulic transmission system to enhance the operational flexibility of the gripping device and to ensure precision in the gripping and releasing operations. Finally, the spreader's control system usually relies on simple mechanical triggers or limit switches to mechanically control the gripping and releasing action, further simplifying operation.Semi-automatic spreaders are widely used in a variety of industries and operating environments, mainly in situations where heavy loads need to be handled and lifted frequently. In ports and harbours, semi-automatic spreaders are often used to handle large cargoes such as containers, steel and ores. Its auto-locking function reduces manual operation and significantly improves operational efficiency while reducing labour intensity. In the warehousing and logistics industry, semi-automatic spreaders are widely used for handling large cargoes, which improves operational efficiency and reduces physical exertion of workers. In the manufacturing industry, semi-automatic spreaders are frequently used in workshops, especially for repetitive tasks such as handling large equipment, raw materials and machine parts. Its efficient operation makes it an important tool in industrial production, helping enterprises to achieve more efficient logistics management in the production process.Semi-automatic spreaders have many significant advantages over traditional manual spreaders. Firstly, its ease of operation is one of its best features. The automatic locking and releasing function reduces the complexity of manual operation, so that workers do not need to spend too much energy on the tedious details of operation. Secondly, the semi-automatic spreader excels in safety. The automatic locking mechanism ensures that heavy loads are not accidentally dislodged during lifting and movement, thus greatly reducing operational risks. Thirdly, the semi-automatic spreader is highly adaptable, with a variety of gripping devices designed to accommodate objects of different shapes and sizes, allowing it to be used flexibly in a variety of scenarios. Finally, semi-automatic spreaders significantly improve work efficiency by reducing unnecessary manual intervention, especially in work environments that require high-frequency operations.Our Services1. 12 months warranty after installation and commissioning in addition to the human damage factors.2. 2 years spare-parts provided for better maintenances.3.
