The slag extractor is the main equipment used for mechanical slag discharge in thermal power plants. It is located at the bottom of large boilers, and the ash discharged from the boiler is discharged through the end of the slag extractor, and then transported by a conveyor to efficiently complete the discharge of boiler waste. The main components of the slag scraper include the scraper chain assembly, the guide wheel system assembly, the drive system, the electronic control system, and the slag scraper body assembly.

Due to long-term operation, the slag conveyor is inevitably prone to internal malfunctions. When the chain of the slag conveyor derails, maintenance technicians will use the Guanhang chain hoist to assist in the installation of the chain.

The specific application process is as follows: first, lower the tensioning device, then hang the chain on the hook of the chain hoist. After starting the slag conveyor, cut and replace the parts of the chain that are stretched or severely worn, and accurately measure the length of the chains on both sides. Then adjust them to make the total length of the chains on both sides basically the same.

In the emergency repair work for the derailment of the slag conveyor chain in the factory, the chain hoist played its unique lifting advantage. The manual pulling of the chain not only solved the lifting problem, but also ensured the accuracy of chain installation and adjustment.
