A clean and explosion-proof fully automatic crane developed and produced for the semiconductor grade polycrystalline silicon project of Jiangsu Xinhua Semiconductor Materials Technology Co., Ltd. To meet the production process requirements, the crane can automatically operate the reduction furnace and silicon rod tools from the reduction furnace platform, cleaning platform, transfer platform, rod dismantling tool and other positions according to the set work route, and accurately locate them. Equipped with the following advanced technologies: adopting a highly sealed explosion-proof driving mechanism and maintenance free self-lubricating bearings. A compact design that integrates motor, reducer, brake, and electrical monitoring. 1. Clean dust removal utilizes high-pressure anti-static spraying technology and structural sealing welding technology to ensure that the entire machine has the characteristics of non stick dust and non dust production. Dust particles and lubricating oil stains are automatically cleaned through permanent magnet machinery, explosion-proof electric dust collectors, mechanical oil collection trays, and other devices. Experience an ultra-low noise environment. 2. On the premise of cleanliness and intelligence, the safety and explosion-proof function adds another highlight to it. The action in any space is in an explosion-proof state, making the operation of the crane safer and more reliable. 3. Intelligent operation has functions such as fully automatic unmanned operation, anti swing automatic precise positioning, automatic hook and unload, etc. The positioning accuracy can reach units below millimeters. 4. The unmanned function is equipped with humanized functions such as automatic fault alarm, automatic detection of fault causes, and component life setting alarm.
