Preparation before installation
Inspect components: Ensure that the slewing chain and its related components, such as sprockets, chains, tensioners, etc., are not damaged, deformed or worn, and the surface should be smooth without burrs and flaws.
Clean the work area: Clean the debris, dust and oil stains in the escalator shaft and installation location to ensure a clean and tidy installation environment.
Prepare tools: Prepare the required installation tools, such as wrenches, screwdrivers, vernier calipers, dynamometers, etc.

Debugging and testing after installation
Manual turning: Before power-on operation, manually turn the drive wheel of the escalator to make the slewing chain drive the steps or pedals of the escalator to move slowly, and check whether the chain runs smoothly and whether there is any jamming, abnormal noise or abnormal resistance.
No-load test run: Turn on the power and let the escalator run a no-load test run. During the test run, closely observe the operation of the slewing chain, including the tension of the chain, the rotation of the sprocket, the working state of the guide device, etc. At the same time, check whether the running speed of the escalator is stable and whether there is any abnormal vibration or noise.
Load test: After the no-load test run is normal, perform a load test. Gradually increase the load of the escalator and observe the operation of the slewing chain under different load conditions. Pay attention to check whether the tension of the chain changes, whether the meshing of the sprocket and the chain is good, and whether the operation of the escalator is still stable and reliable.
