How to diagnose the blockage in the inlet of concrete pump?

Answer:

If it doesn't work, you'll have to clean it up manually and rule it out.
Make the pump reverse running to destroy the caking, return the concrete to the hopper, stir it again, and then pump it forward
The feed port is blocked and the pump operation and hydraulic system are normal, with no abnormal sound and vibration. The hopper has larger aggregate or agglomerates and is stuck or arched at the feed port
