The design concept of stage chain hoist: a perfect combination of safety and practicality

　　1、 Safety first

　　The use environment of stage chain hoists is usually in densely populated stage areas, so safety is the primary consideration in design. In the design process, it is necessary to ensure that the structure of the chain hoist is firm and stable, able to withstand various weights of stage equipment, and that no unexpected situations occur during use.

　　(1) High strength material

　　Use high-strength alloy steel materials to make the main components of the chain hoist, such as chains, hooks, gears, etc. These materials have high strength and wear resistance, and can withstand large tensile and weight forces, ensuring the safety and reliability of the chain hoist.

　　(2) Precision manufacturing process

　　Adopting precise manufacturing processes to ensure high fitting accuracy and smooth operation between various components of the chain hoist. For example, the pitch and diameter of the chain must be precisely controlled to ensure that the chain does not experience jamming or jumping during operation.

　　(3) Safety protection device

　　Equipped with various safety protection devices, such as overload protection, limit protection, braking device, etc. The overload protection device can automatically stop working when the tension borne by the chain hoist exceeds the rated value, avoiding chain breakage or damage to other components; The limit protection device can limit the lifting height of the chain hoist, preventing accidents caused by excessive lifting of stage equipment; The braking device can quickly lock the chain when the chain hoist stops working, preventing the stage equipment from descending due to gravity.

　　2、 Easy to operate

　　The frequency of using stage chain hoists is usually high, so ease of operation is also an important consideration in design. In the design process, it is necessary to ensure that the operation of the chain hoist is simple and convenient, and it can quickly complete the lifting and moving tasks of the stage equipment.

　　(1) Humanized design

　　Adopting a humanized design concept, the operation of the chain hoist is more in line with ergonomic principles. For example, the shape and size of the handle must be suitable for human grip, making it more comfortable and effortless to operate; The length and diameter of the chain must be moderate, meeting the lifting height requirements of the stage equipment without being too heavy or difficult to operate.

　　(2) Lightweight and flexible

　　Design a lightweight and flexible chain hoist for easy carrying and transportation. For example, lightweight materials such as aluminum alloy can be used to make the shell of the chain hoist, reducing the overall weight; Meanwhile, a foldable handle and chain are designed for easy storage and storage.

　　(3) Quick installation and disassembly

　　Design a chain hoist for quick installation and disassembly, capable of completing stage equipment installation and disassembly tasks in a short period of time. For example, a quick connection device can be used to quickly connect and disconnect the hook and chain of the chain hoist from the stage equipment; At the same time, the design of the shell is easy to install and disassemble, making it convenient for the manual hoist to be maintained and serviced
