Question

Accepted Answer

The interviewer asked about handling of batching plant, concrete pump, loader, double horn shovels, TM rear engine, mixer, engine overhauling, motor burnout prevention, and difference between s valve and rock valve of concrete pump.

Handled batching plant with a capacity of 60 cubic meters per hour
Managed a concrete pump with a maximum output of 120 cubic meters per hour
Operated a loader with a bucket capacity of 2.5 cubic meters
Double horn shovels have a life of approximately 500 hours
Chemical composition of double horn shovels is typically made of high carbon steel
TM rear engine to drum mechanism uses a hydraulic pump to transfer power from the engine to the drum
Dry volume of mixer is the volume of the drum, while concrete volume is the volume of the mixture inside the drum
Engine overhauling should be done after every 10,000 hours of operation
To prevent motor burnout, ensure proper lubrication, avoid overloading, and maintain proper voltage and current levels
S valve and rock valve are both types of concrete pump valves, with s valve being more commonly used due to its higher efficiency
