Electric multiple units, driven by electricity and designed with distributed power, have many significant advantages compared to centralized railway vehicles. Its acceleration and deceleration performance is better, and the weight distribution is more even, which not only makes the train run more smoothly, but also effectively reduces the loss of tracks.
In the assembly process of electric multiple units, every link is crucial. From the installation of equipment under the train, such as derailleurs, deflectors, auxiliary converters, waste exhaust ducts, etc., to the assembly of equipment inside the train, including cold resistant materials, floor wood bones, side wall panels, car windows, luggage racks, seats, kitchen facilities, etc., to the installation of equipment in the driver's cab and the assembly of equipment on the roof, such as roof equipment covers, pantographs, etc., every step requires precise operation to ensure the quality and performance of the high-speed train.
In order to accelerate the assembly process of electric multiple units, the electric chain hoist has played an important role. Ring chain electric hoist is a device that combines the deceleration mechanism and braking mechanism of the lifting chain. It drives the sprocket that meshes with the lifting chain to rotate at a reduced speed through an electric motor, thereby achieving the lifting and lowering of goods. When assembling high-speed trains, for some heavier components such as large equipment modules, under car suspension parts, etc., using a chain electric hoist for lifting operations can quickly and accurately lift them to designated positions for installation. Compared to manual handling, it greatly improves work efficiency and shortens assembly time.
The loop chain electric hoist can also be combined with a lateral displacement device, which is extremely advantageous for lifting operations that require precise positioning, further ensuring the accuracy and quality of assembly, helping electric multiple units to complete assembly efficiently and with high quality, and providing reliable equipment support for modern railway transportation.
