The crane is a crane with automatic, clean and explosion-proof functions that meets the new production process. The operating environment is a semiconductor material workshop, with a dust-free design, and the air cleanliness level is level 4 (national standard level 7) (that is, no more than 10,000 particles with a size of 0.1 μm per cubic meter). At the same time, there are flammable and explosive gases in the workshop, and the explosion-proof level of the crane is dIICT4. The crane is automatically controlled by the computer in the central control room, and can automatically run the reduction furnace and silicon rod tools from the reduction furnace platform, cleaning platform, transfer platform, rod removal tool and other positions according to the set working route.
